1 2 Advanced Linux Sound Architecture - Driver 3 ========================================== 4 Configuration guide 5 6 7Kernel Configuration 8==================== 9 10To enable ALSA support you need at least to build the kernel with 11primary sound card support (CONFIG_SOUND). Since ALSA can emulate OSS, 12you don't have to choose any of the OSS modules. 13 14Enable "OSS API emulation" (CONFIG_SND_OSSEMUL) and both OSS mixer and 15PCM supports if you want to run OSS applications with ALSA. 16 17If you want to support the WaveTable functionality on cards such as 18SB Live! then you need to enable "Sequencer support" 19(CONFIG_SND_SEQUENCER). 20 21To make ALSA debug messages more verbose, enable the "Verbose printk" 22and "Debug" options. To check for memory leaks, turn on "Debug memory" 23too. "Debug detection" will add checks for the detection of cards. 24 25Please note that all the ALSA ISA drivers support the Linux isapnp API 26(if the card supports ISA PnP). You don't need to configure the cards 27using isapnptools. 28 29 30Creating ALSA devices 31===================== 32 33This depends on your distribution, but normally you use the /dev/MAKEDEV 34script to create the necessary device nodes. On some systems you use a 35script named 'snddevices'. 36 37 38Module parameters 39================= 40 41The user can load modules with options. If the module supports more than 42one card and you have more than one card of the same type then you can 43specify multiple values for the option separated by commas. 44 45Prior to version 0.9.0rc4 options had a 'snd_' prefix. This was removed. 46 47 Module snd 48 ---------- 49 50 The core ALSA module. It is used by all ALSA card drivers. 51 It takes the following options which have global effects. 52 53 major - major number for sound driver 54 - Default: 116 55 cards_limit 56 - limiting card index for auto-loading (1-8) 57 - Default: 1 58 - For auto-loading more than one card, specify this 59 option together with snd-card-X aliases. 60 slots - Reserve the slot index for the given driver. 61 This option takes multiple strings. 62 See "Module Autoloading Support" section for details. 63 debug - Specifies the debug message level 64 (0 = disable debug prints, 1 = normal debug messages, 65 2 = verbose debug messages) 66 This option appears only when CONFIG_SND_DEBUG=y. 67 This option can be dynamically changed via sysfs 68 /sys/modules/snd/parameters/debug file. 69 70 Module snd-pcm-oss 71 ------------------ 72 73 The PCM OSS emulation module. 74 This module takes options which change the mapping of devices. 75 76 dsp_map - PCM device number maps assigned to the 1st OSS device. 77 - Default: 0 78 adsp_map - PCM device number maps assigned to the 2st OSS device. 79 - Default: 1 80 nonblock_open 81 - Don't block opening busy PCM devices. Default: 1 82 83 For example, when dsp_map=2, /dev/dsp will be mapped to PCM #2 of 84 the card #0. Similarly, when adsp_map=0, /dev/adsp will be mapped 85 to PCM #0 of the card #0. 86 For changing the second or later card, specify the option with 87 commas, such like "dsp_map=0,1". 88 89 nonblock_open option is used to change the behavior of the PCM 90 regarding opening the device. When this option is non-zero, 91 opening a busy OSS PCM device won't be blocked but return 92 immediately with EAGAIN (just like O_NONBLOCK flag). 93 94 Module snd-rawmidi 95 ------------------ 96 97 This module takes options which change the mapping of devices. 98 similar to those of the snd-pcm-oss module. 99 100 midi_map - MIDI device number maps assigned to the 1st OSS device. 101 - Default: 0 102 amidi_map - MIDI device number maps assigned to the 2st OSS device. 103 - Default: 1 104 105 Common parameters for top sound card modules 106 -------------------------------------------- 107 108 Each of top level sound card module takes the following options. 109 110 index - index (slot #) of sound card 111 - Values: 0 through 31 or negative 112 - If nonnegative, assign that index number 113 - if negative, interpret as a bitmask of permissible 114 indices; the first free permitted index is assigned 115 - Default: -1 116 id - card ID (identifier or name) 117 - Can be up to 15 characters long 118 - Default: the card type 119 - A directory by this name is created under /proc/asound/ 120 containing information about the card 121 - This ID can be used instead of the index number in 122 identifying the card 123 enable - enable card 124 - Default: enabled, for PCI and ISA PnP cards 125 126 Module snd-adlib 127 ---------------- 128 129 Module for AdLib FM cards. 130 131 port - port # for OPL chip 132 133 This module supports multiple cards. It does not support autoprobe, so 134 the port must be specified. For actual AdLib FM cards it will be 0x388. 135 Note that this card does not have PCM support and no mixer; only FM 136 synthesis. 137 138 Make sure you have "sbiload" from the alsa-tools package available and, 139 after loading the module, find out the assigned ALSA sequencer port 140 number through "sbiload -l". Example output: 141 142 Port Client name Port name 143 64:0 OPL2 FM synth OPL2 FM Port 144 145 Load the std.sb and drums.sb patches also supplied by sbiload: 146 147 sbiload -p 64:0 std.sb drums.sb 148 149 If you use this driver to drive an OPL3, you can use std.o3 and drums.o3 150 instead. To have the card produce sound, use aplaymidi from alsa-utils: 151 152 aplaymidi -p 64:0 foo.mid 153 154 Module snd-ad1816a 155 ------------------ 156 157 Module for sound cards based on Analog Devices AD1816A/AD1815 ISA chips. 158 159 clockfreq - Clock frequency for AD1816A chip (default = 0, 33000Hz) 160 161 This module supports multiple cards, autoprobe and PnP. 162 163 Module snd-ad1848 164 ----------------- 165 166 Module for sound cards based on AD1848/AD1847/CS4248 ISA chips. 167 168 port - port # for AD1848 chip 169 irq - IRQ # for AD1848 chip 170 dma1 - DMA # for AD1848 chip (0,1,3) 171 172 This module supports multiple cards.

force the model name 795 position_fix - Fix DMA pointer (0 = auto, 1 = use LPIB, 2 = POSBUF) 796 probe_mask - Bitmask to probe codecs (default = -1, meaning all slots) 797 When the bit 8 (0x100) is set, the lower 8 bits are used 798 as the "fixed" codec slots; i.e. the driver probes the 799 slots regardless what hardware reports back 800 probe_only - Only probing and no codec initialization (default=off); 801 Useful to check the initial codec status for debugging 802 bdl_pos_adj - Specifies the DMA IRQ timing delay in samples. 803 Passing -1 will make the driver to choose the appropriate 804 value based on the controller chip. 805 patch - Specifies the early "patch" files to modify the HD-audio 806 setup before initializing the codecs. This option is 807 available only when CONFIG_SND_HDA_PATCH_LOADER=y is set. 808 See HD-Audio.txt for details. 809 beep_mode - Selects the beep registration mode (0=off, 1=on, 2= 810 dynamic registration via mute switch on/off); the default 811 value is set via CONFIG_SND_HDA_INPUT_BEEP_MODE kconfig. 812 813 [Single (global) options] 814 single_cmd - Use single immediate commands to communicate with 815 codecs (for debugging only) 816 enable_msi - Enable Message Signaled Interrupt (MSI) (default = off) 817 power_save - Automatic power-saving timeout (in second, 0 = 818 disable) 819 power_save_controller - Reset HD-audio controller in power-saving mode 820 (default = on) 821 822 This module supports multiple cards and autoprobe. 823 824 See Documentation/sound/alsa/HD-Audio.txt for more details about 825 HD-audio driver. 826 827 Each codec may have a model table for different configurations. 828 If your machine isn't listed there, the default (usually minimal) 829 configuration is set up. You can pass "model=<name>" option to 830 specify a certain model in such a case. There are different 831 models depending on the codec chip. The list of available models 832 is found in HD-Audio-Models.txt 833 834 The model name "genric" is treated as a special case. When this 835 model is given, the driver uses the generic codec parser without 836 "codec-patch". It's sometimes good for testing and debugging. 837 838 If the default configuration doesn't work and one of the above 839 matches with your device, report it together with alsa-info.sh 840 output (with --no-upload option) to kernel bugzilla or alsa-devel 841 ML (see the section "Links and Addresses"). 842 843 power_save and power_save_controller options are for power-saving 844 mode. See powersave.txt for details. 845 846 Note 2: If you get click noises on output, try the module option 847 position_fix=1 or 2. position_fix=1 will use the SD_LPIB 848 register value without FIFO size correction as the current 849 DMA pointer. position_fix=2 will make the driver to use 850 the position buffer instead of reading SD_LPIB register. 851 (Usually SD_LPIB register is more accurate than the 852 position buffer.) 853 854 NB: If you get many "azx_get_response timeout" messages at 855 loading, it's likely a problem of interrupts (e.g. ACPI irq 856 routing). Try to boot with options like "pci=noacpi". Also, you 857 can try "single_cmd=1" module option. This will switch the 858 communication method between HDA controller and codecs to the 859 single immediate commands instead of CORB/RIRB. Basically, the 860 single command mode is provided only for BIOS, and you won't get 861 unsolicited events, too. But, at least, this works independently 862 from the irq. Remember this is a last resort, and should be 863 avoided as much as possible... 864 865 MORE NOTES ON "azx_get_response timeout" PROBLEMS: 866 On some hardwares, you may need to add a proper probe_mask option 867 to avoid the "azx_get_response timeout" problem above, instead. 868 This occurs when the access to non-existing or non-working codec slot 869 (likely a modem one) causes a stall of the communication via HD-audio 870 bus. You can see which codec slots are probed by enabling 871 CONFIG_SND_DEBUG_VERBOSE, or simply from the file name of the codec 872 proc files. Then limit the slots to probe by probe_mask option. 873 For example, probe_mask=1 means to probe only the first slot, and 874 probe_mask=4 means only the third slot. 875 876 The power-management is supported. 877 878 Module snd-hdsp 879 --------------- 880 881 Module for RME Hammerfall DSP audio interface(s) 882 883 This module supports multiple cards. 884 885 Note: The firmware data can be automatically loaded via hotplug 886 when CONFIG_FW_LOADER is set. Otherwise, you need to load 887 the firmware via hdsploader utility included in alsa-tools 888 package. 889 The firmware data is found in alsa-firmware package. 890 891 Note: snd-page-alloc module does the job which snd-hammerfall-mem 892 module did formerly. It will allocate the buffers in advance 893 when any HDSP cards are found. To make the buffer 894 allocation sure, load snd-page-alloc module in the early 895 stage of boot sequence. See "Early Buffer Allocation" 896 section. 897 898 Module snd-hdspm 899 ---------------- 900 901 Module for RME HDSP MADI board. 902 903 precise_ptr - Enable precise pointer, or disable. 904 line_outs_monitor - Send playback streams to analog outs by default. 905 enable_monitor - Enable Analog Out on Channel 63/64 by default. 906 907 See hdspm.txt for details. 908 909 Module snd-hifier 910 ----------------- 911 912 Module for the MediaTek/TempoTec HiFier Fantasia sound card. 913 914 This module supports autoprobe and multiple cards. 915 916 Module snd-ice1712 917 ------------------ 918 919 Module for Envy24 (ICE1712) based PCI sound cards. 920 * MidiMan M Audio Delta 1010 921 * MidiMan M Audio Delta 1010LT 922 * MidiMan M Audio Delta DiO 2496 923 * MidiMan M Audio Delta 66 924 * MidiMan M Audio Delta 44 925 * MidiMan M Audio Delta 410 926 * MidiMan M Audio Audiophile 2496 927 * TerraTec EWS 88MT 928 * TerraTec EWS 88D 929 * TerraTec EWX 24/96 930 * TerraTec DMX 6Fire 931 * TerraTec Phase 88 932 * Hoontech SoundTrack DSP 24 933 * Hoontech SoundTrack DSP 24 Value 934 * Hoontech SoundTrack DSP 24 Media 7.1 935 * Event Electronics, EZ8 936 * Digigram VX442 937 * Lionstracs, Mediastaton 938 * Terrasoniq TS 88 939 940 model - Use the given board model, one of the following: 941 delta1010, dio2496, delta66, delta44, audiophile, delta410, 942 delta1010lt, vx442, ewx2496, ews88mt, ews88mt_new, ews88d, 943 dmx6fire, dsp24, dsp24_value, dsp24_71, ez8, 944 phase88, mediastation 945 omni - Omni I/O support for MidiMan M-Audio Delta44/66 946 cs8427_timeout - reset timeout for the CS8427 chip (S/PDIF transceiver) 947 in msec resolution, default value is 500 (0.5 sec) 948 949 This module supports multiple cards and autoprobe.

Note that it has been discontinued, but the 1286 Voyetra Turtle Beach knowledge base entry for it is still available 1287 at 1288 http://www.turtlebeach.com 1289 1290 Module snd-msnd-pinnacle 1291 ------------------------ 1292 1293 Module for Turtle Beach MultiSound Pinnacle/Fiji soundcards. 1294 1295 io - Port # for pinnacle/fiji card 1296 irq - IRQ # for pinnalce/fiji card 1297 mem - Memory address (0xb0000, 0xc8000, 0xd0000, 0xd8000, 1298 0xe0000 or 0xe8000) 1299 write_ndelay - enable write ndelay (default = 1) 1300 calibrate_signal - calibrate signal (default = 0) 1301 isapnp - ISA PnP detection - 0 = disable, 1 = enable (default) 1302 1303 The driver requires firmware files "turtlebeach/pndspini.bin" and 1304 "turtlebeach/pndsperm.bin" in the proper firmware directory. 1305 1306 Module snd-mtpav 1307 ---------------- 1308 1309 Module for MOTU MidiTimePiece AV multiport MIDI (on the parallel 1310 port). 1311 1312 port - I/O port # for MTPAV (0x378,0x278, default=0x378) 1313 irq - IRQ # for MTPAV (7,5, default=7) 1314 hwports - number of supported hardware ports, default=8. 1315 1316 Module supports only 1 card. This module has no enable option. 1317 1318 Module snd-mts64 1319 ---------------- 1320 1321 Module for Ego Systems (ESI) Miditerminal 4140 1322 1323 This module supports multiple devices. 1324 Requires parport (CONFIG_PARPORT). 1325 1326 Module snd-nm256 1327 ---------------- 1328 1329 Module for NeoMagic NM256AV/ZX chips 1330 1331 playback_bufsize - max playback frame size in kB (4-128kB) 1332 capture_bufsize - max capture frame size in kB (4-128kB) 1333 force_ac97 - 0 or 1 (disabled by default) 1334 buffer_top - specify buffer top address 1335 use_cache - 0 or 1 (disabled by default) 1336 vaio_hack - alias buffer_top=0x25a800 1337 reset_workaround - enable AC97 RESET workaround for some laptops 1338 reset_workaround2 - enable extended AC97 RESET workaround for some 1339 other laptops 1340 1341 This module supports one chip and autoprobe. 1342 1343 The power-management is supported. 1344 1345 Note: on some notebooks the buffer address cannot be detected 1346 automatically, or causes hang-up during initialization. 1347 In such a case, specify the buffer top address explicitly via 1348 the buffer_top option. 1349 For example, 1350 Sony F250: buffer_top=0x25a800 1351 Sony F270: buffer_top=0x272800 1352 The driver supports only ac97 codec. It's possible to force 1353 to initialize/use ac97 although it's not detected. In such a 1354 case, use force_ac97=1 option - but *NO* guarantee whether it 1355 works! 1356 1357 Note: The NM256 chip can be linked internally with non-AC97 1358 codecs. This driver supports only the AC97 codec, and won't work 1359 with machines with other (most likely CS423x or OPL3SAx) chips, 1360 even though the device is detected in lspci. In such a case, try 1361 other drivers, e.g. snd-cs4232 or snd-opl3sa2. Some has ISA-PnP 1362 but some doesn't have ISA PnP. You'll need to specify isapnp=0 1363 and proper hardware parameters in the case without ISA PnP. 1364 1365 Note: some laptops need a workaround for AC97 RESET. For the 1366 known hardware like Dell Latitude LS and Sony PCG-F305, this 1367 workaround is enabled automatically. For other laptops with a 1368 hard freeze, you can try reset_workaround=1 option. 1369 1370 Note: Dell Latitude CSx laptops have another problem regarding 1371 AC97 RESET. On these laptops, reset_workaround2 option is 1372 turned on as default. This option is worth to try if the 1373 previous reset_workaround option doesn't help. 1374 1375 Note: This driver is really crappy. It's a porting from the 1376 OSS driver, which is a result of black-magic reverse engineering. 1377 The detection of codec will fail if the driver is loaded *after* 1378 X-server as described above. You might be able to force to load 1379 the module, but it may result in hang-up. Hence, make sure that 1380 you load this module *before* X if you encounter this kind of 1381 problem. 1382 1383 Module snd-opl3sa2 1384 ------------------ 1385 1386 Module for Yamaha OPL3-SA2/SA3 sound cards. 1387 1388 isapnp - ISA PnP detection - 0 = disable, 1 = enable (default) 1389 1390 with isapnp=0, the following options are available: 1391 1392 port - control port # for OPL3-SA chip (0x370) 1393 sb_port - SB port # for OPL3-SA chip (0x220,0x240) 1394 wss_port - WSS port # for OPL3-SA chip (0x530,0xe80,0xf40,0x604) 1395 midi_port - port # for MPU-401 UART (0x300,0x330), -1 = disable 1396 fm_port - FM port # for OPL3-SA chip (0x388), -1 = disable 1397 irq - IRQ # for OPL3-SA chip (5,7,9,10) 1398 dma1 - first DMA # for Yamaha OPL3-SA chip (0,1,3) 1399 dma2 - second DMA # for Yamaha OPL3-SA chip (0,1,3), -1 = disable 1400 1401 This module supports multiple cards and ISA PnP. It does not support 1402 autoprobe (if ISA PnP is not used) thus all ports must be specified!!! 1403 1404 The power-management is supported. 1405 1406 Module snd-opti92x-ad1848 1407 ------------------------- 1408 1409 Module for sound cards based on OPTi 82c92x and Analog Devices AD1848 chips. 1410 Module works with OAK Mozart cards as well. 1411 1412 isapnp - ISA PnP detection - 0 = disable, 1 = enable (default) 1413 1414 with isapnp=0, the following options are available: 1415 1416 port - port # for WSS chip (0x530,0xe80,0xf40,0x604) 1417 mpu_port - port # for MPU-401 UART (0x300,0x310,0x320,0x330) 1418 fm_port - port # for OPL3 device (0x388) 1419 irq - IRQ # for WSS chip (5,7,9,10,11) 1420 mpu_irq - IRQ # for MPU-401 UART (5,7,9,10) 1421 dma1 - first DMA # for WSS chip (0,1,3) 1422 1423 This module supports only one card, autoprobe and PnP. 1424 1425 Module snd-opti92x-cs4231 1426 ------------------------- 1427 1428 Module for sound cards based on OPTi 82c92x and Crystal CS4231 chips. 1429 1430 isapnp - ISA PnP detection - 0 = disable, 1 = enable (default) 1431 1432 with isapnp=0, the following options are available: 1433 1434 port - port # for WSS chip (0x530,0xe80,0xf40,0x604) 1435 mpu_port - port # for MPU-401 UART (0x300,0x310,0x320,0x330) 1436 fm_port - port # for OPL3 device (0x388) 1437 irq - IRQ # for WSS chip (5,7,9,10,11) 1438 mpu_irq - IRQ # for MPU-401 UART (5,7,9,10) 1439 dma1 - first DMA # for WSS chip (0,1,3) 1440 dma2 - second DMA # for WSS chip (0,1,3) 1441 1442 This module supports only one card, autoprobe and PnP. 1443 1444 Module snd-opti93x 1445 ------------------ 1446 1447 Module for sound cards based on OPTi 82c93x chips. 1448 1449 isapnp - ISA PnP detection - 0 = disable, 1 = enable (default) 1450 1451 with isapnp=0, the following options are available: 1452 1453 port - port # for WSS chip (0x530,0xe80,0xf40,0x604) 1454 mpu_port - port # for MPU-401 UART (0x300,0x310,0x320,0x330) 1455 fm_port - port # for OPL3 device (0x388) 1456 irq - IRQ # for WSS chip (5,7,9,10,11) 1457 mpu_irq - IRQ # for MPU-401 UART (5,7,9,10) 1458 dma1 - first DMA # for WSS chip (0,1,3) 1459 dma2 - second DMA # for WSS chip (0,1,3) 1460 1461 This module supports only one card, autoprobe and PnP. 1462 1463 Module snd-oxygen 1464 ----------------- 1465 1466 Module for sound cards based on the C-Media CMI8788 chip: 1467 * Asound A-8788 1468 * AuzenTech X-Meridian 1469 * Bgears b-Enspirer 1470 * Club3D Theatron DTS 1471 * HT-Omega Claro (plus) 1472 * HT-Omega Claro halo (XT) 1473 * Razer Barracuda AC-1 1474 * Sondigo Inferno 1475 1476 This module supports autoprobe and multiple cards. 1477 1478 Module snd-pcsp 1479 ----------------- 1480 1481 Module for internal PC-Speaker. 1482 1483 nopcm - Disable PC-Speaker PCM sound.

Assume that we need to boot the OS (default:no) 1719 If yes, then during driver loading, the state of the board is 1720 ignored, and we reset the board and load the firmware anyway. 1721 fx_raw - Assume that the FX process needs help (default:yes) 1722 If false, we'll leave the FX processor in whatever state it is 1723 when the driver is loaded. The default is to download the 1724 microprogram and associated coefficients to set it up for 1725 "default" operation, whatever that means. 1726 debug_default - Debug parameters for card initialization 1727 wait_usecs - How long to wait without sleeping, usecs 1728 (default:150) 1729 This magic number seems to give pretty optimal throughput 1730 based on my limited experimentation. 1731 If you want to play around with it and find a better value, be 1732 my guest. Remember, the idea is to get a number that causes us 1733 to just busy wait for as many WaveFront commands as possible, 1734 without coming up with a number so large that we hog the whole 1735 CPU. 1736 Specifically, with this number, out of about 134,000 status 1737 waits, only about 250 result in a sleep. 1738 sleep_interval - How long to sleep when waiting for reply 1739 (default: 100) 1740 sleep_tries - How many times to try sleeping during a wait 1741 (default: 50) 1742 ospath - Pathname to processed ICS2115 OS firmware 1743 (default:wavefront.os) 1744 The path name of the ISC2115 OS firmware. In the recent 1745 version, it's handled via firmware loader framework, so it 1746 must be installed in the proper path, typically, 1747 /lib/firmware. 1748 reset_time - How long to wait for a reset to take effect 1749 (default:2) 1750 ramcheck_time - How many seconds to wait for the RAM test 1751 (default:20) 1752 osrun_time - How many seconds to wait for the ICS2115 OS 1753 (default:10) 1754 1755 This module supports multiple cards and ISA PnP. 1756 1757 Note: the firmware file "wavefront.os" was located in the earlier 1758 version in /etc. Now it's loaded via firmware loader, and 1759 must be in the proper firmware path, such as /lib/firmware. 1760 Copy (or symlink) the file appropriately if you get an error 1761 regarding firmware downloading after upgrading the kernel. 1762 1763 Module snd-sonicvibes 1764 --------------------- 1765 1766 Module for S3 SonicVibes PCI sound cards. 1767 * PINE Schubert 32 PCI 1768 1769 reverb - Reverb Enable - 1 = enable, 0 = disable (default) 1770 - SoundCard must have onboard SRAM for this. 1771 mge - Mic Gain Enable - 1 = enable, 0 = disable (default) 1772 1773 This module supports multiple cards and autoprobe. 1774 1775 Module snd-serial-u16550 1776 ------------------------ 1777 1778 Module for UART16550A serial MIDI ports. 1779 1780 port - port # for UART16550A chip 1781 irq - IRQ # for UART16550A chip, -1 = poll mode 1782 speed - speed in bauds (9600,19200,38400,57600,115200) 1783 38400 = default 1784 base - base for divisor in bauds (57600,115200,230400,460800) 1785 115200 = default 1786 outs - number of MIDI ports in a serial port (1-4) 1787 1 = default 1788 adaptor - Type of adaptor. 1789 0 = Soundcanvas, 1 = MS-124T, 2 = MS-124W S/A, 1790 3 = MS-124W M/B, 4 = Generic 1791 1792 This module supports multiple cards. This module does not support autoprobe 1793 thus the main port must be specified!!! Other options are optional. 1794 1795 Module snd-trident 1796 ------------------ 1797 1798 Module for Trident 4DWave DX/NX sound cards. 1799 * Best Union Miss Melody 4DWave PCI 1800 * HIS 4DWave PCI 1801 * Warpspeed ONSpeed 4DWave PCI 1802 * AzTech PCI 64-Q3D 1803 * Addonics SV 750 1804 * CHIC True Sound 4Dwave 1805 * Shark Predator4D-PCI 1806 * Jaton SonicWave 4D 1807 * SiS SI7018 PCI Audio 1808 * Hoontech SoundTrack Digital 4DWave NX 1809 1810 pcm_channels - max channels (voices) reserved for PCM 1811 wavetable_size - max wavetable size in kB (4-?kb) 1812 1813 This module supports multiple cards and autoprobe. 1814 1815 The power-management is supported. 1816 1817 Module snd-ua101 1818 ---------------- 1819 1820 Module for the Edirol UA-101/UA-1000 audio/MIDI interfaces. 1821 1822 This module supports multiple devices, autoprobe and hotplugging. 1823 1824 Module snd-usb-audio 1825 -------------------- 1826 1827 Module for USB audio and USB MIDI devices. 1828 1829 vid - Vendor ID for the device (optional) 1830 pid - Product ID for the device (optional) 1831 nrpacks - Max. number of packets per URB (default: 8) 1832 async_unlink - Use async unlink mode (default: yes) 1833 device_setup - Device specific magic number (optional) 1834 - Influence depends on the device 1835 - Default: 0x0000 1836 ignore_ctl_error - Ignore any USB-controller regarding mixer 1837 interface (default: no) 1838 1839 This module supports multiple devices, autoprobe and hotplugging. 1840 1841 NB: nrpacks parameter can be modified dynamically via sysfs. 1842 Don't put the value over 20. Changing via sysfs has no sanity 1843 check. 1844 NB: async_unlink=0 would cause Oops. It remains just for 1845 debugging purpose (if any). 1846 NB: ignore_ctl_error=1 may help when you get an error at accessing 1847 the mixer element such as URB error -22. This happens on some 1848 buggy USB device or the controller. 1849 1850 Module snd-usb-caiaq 1851 -------------------- 1852 1853 Module for caiaq UB audio interfaces, 1854 * Native Instruments RigKontrol2 1855 * Native Instruments Kore Controller 1856 * Native Instruments Audio Kontrol 1 1857 * Native Instruments Audio 8 DJ 1858 1859 This module supports multiple devices, autoprobe and hotplugging. 1860 1861 Module snd-usb-usx2y 1862 -------------------- 1863 1864 Module for Tascam USB US-122, US-224 and US-428 devices. 1865 1866 This module supports multiple devices, autoprobe and hotplugging. 1867 1868 Note: you need to load the firmware via usx2yloader utility included 1869 in alsa-tools and alsa-firmware packages. 1870 1871 Module snd-via82xx 1872 ------------------ 1873 1874 Module for AC'97 motherboards based on VIA 82C686A/686B, 8233, 1875 8233A, 8233C, 8235, 8237 (south) bridge. 1876 1877 mpu_port - 0x300,0x310,0x320,0x330, otherwise obtain BIOS setup 1878 [VIA686A/686B only] 1879 joystick - Enable joystick (default off) [VIA686A/686B only] 1880 ac97_clock - AC'97 codec clock base (default 48000Hz) 1881 dxs_support - support DXS channels, 1882 0 = auto (default), 1 = enable, 2 = disable, 1883 3 = 48k only, 4 = no VRA, 5 = enable any sample 1884 rate and different sample rates on different 1885 channels 1886 [VIA8233/C, 8235, 8237 only] 1887 ac97_quirk - AC'97 workaround for strange hardware 1888 See "AC97 Quirk Option" section below. 1889 1890 This module supports one chip and autoprobe. 1891 1892 Note: on some SMP motherboards like MSI 694D the interrupts might 1893 not be generated properly. In such a case, please try to 1894 set the SMP (or MPS) version on BIOS to 1.1 instead of 1895 default value 1.4. Then the interrupt number will be 1896 assigned under 15. You might also upgrade your BIOS. 1897 1898 Note: VIA8233/5/7 (not VIA8233A) can support DXS (direct sound) 1899 channels as the first PCM. On these channels, up to 4 1900 streams can be played at the same time, and the controller 1901 can perform sample rate conversion with separate rates for 1902 each channel. 1903 As default (dxs_support = 0), 48k fixed rate is chosen 1904 except for the known devices since the output is often 1905 noisy except for 48k on some mother boards due to the 1906 bug of BIOS. 1907 Please try once dxs_support=5 and if it works on other 1908 sample rates (e.g. 44.1kHz of mp3 playback), please let us 1909 know the PCI subsystem vendor/device id's (output of 1910 "lspci -nv"). 1911 If dxs_support=5 does not work, try dxs_support=4; if it 1912 doesn't work too, try dxs_support=1. (dxs_support=1 is 1913 usually for old motherboards. The correct implemented 1914 board should work with 4 or 5.) If it still doesn't 1915 work and the default setting is ok, dxs_support=3 is the 1916 right choice. If the default setting doesn't work at all, 1917 try dxs_support=2 to disable the DXS channels. 1918 In any cases, please let us know the result and the 1919 subsystem vendor/device ids. See "Links and Addresses" 1920 below. 1921 1922 Note: for the MPU401 on VIA823x, use snd-mpu401 driver 1923 additionally. The mpu_port option is for VIA686 chips only. 1924 1925 The power-management is supported. 1926 1927 Module snd-via82xx-modem 1928 ------------------------ 1929 1930 Module for VIA82xx AC97 modem 1931 1932 ac97_clock - AC'97 codec clock base (default 48000Hz) 1933 1934 This module supports one card and autoprobe. 1935 1936 Note: The default index value of this module is -2, i.e. the first 1937 slot is excluded. 1938 1939 The power-management is supported. 1940 1941 Module snd-virmidi 1942 ------------------ 1943 1944 Module for virtual rawmidi devices. 1945 This module creates virtual rawmidi devices which communicate 1946 to the corresponding ALSA sequencer ports. 1947 1948 midi_devs - MIDI devices # (1-4, default=4) 1949 1950 This module supports multiple cards. 1951 1952 Module snd-virtuoso 1953 ------------------- 1954 1955 Module for sound cards based on the Asus AV100/AV200 chips, 1956 i.e., Xonar D1, DX, D2, D2X, DS, HDAV1.3 (Deluxe), Essence ST 1957 (Deluxe) and Essence STX. 1958 1959 This module supports autoprobe and multiple cards. 1960 1961 Module snd-vx222 1962 ---------------- 1963 1964 Module for Digigram VX-Pocket VX222, V222 v2 and Mic cards. 1965 1966 mic - Enable Microphone on V222 Mic (NYI) 1967 ibl - Capture IBL size. (default = 0, minimum size) 1968 1969 This module supports multiple cards. 1970 1971 When the driver is compiled as a module and the hotplug firmware 1972 is supported, the firmware data is loaded via hotplug automatically. 1973 Install the necessary firmware files in alsa-firmware package. 1974 When no hotplug fw loader is available, you need to load the 1975 firmware via vxloader utility in alsa-tools package. To invoke 1976 vxloader automatically, add the following to /etc/modprobe.conf 1977 1978 install snd-vx222 /sbin/modprobe --first-time -i snd-vx222 && /usr/bin/vxloader 1979 1980 (for 2.2/2.4 kernels, add "post-install /usr/bin/vxloader" to 1981 /etc/modules.conf, instead.) 1982 IBL size defines the interrupts period for PCM. The smaller size 1983 gives smaller latency but leads to more CPU consumption, too. 1984 The size is usually aligned to 126. As default (=0), the smallest 1985 size is chosen. The possible IBL values can be found in 1986 /proc/asound/cardX/vx-status proc file. 1987 1988 The power-management is supported. 1989 1990 Module snd-vxpocket 1991 ------------------- 1992 1993 Module for Digigram VX-Pocket VX2 and 440 PCMCIA cards. 1994 1995 ibl - Capture IBL size. (default = 0, minimum size) 1996 1997 This module supports multiple cards. The module is compiled only when 1998 PCMCIA is supported on kernel. 1999 2000 With the older 2.6.x kernel, to activate the driver via the card 2001 manager, you'll need to set up /etc/pcmcia/vxpocket.conf. See the 2002 sound/pcmcia/vx/vxpocket.c. 2.6.13 or later kernel requires no 2003 longer require a config file. 2004 2005 When the driver is compiled as a module and the hotplug firmware 2006 is supported, the firmware data is loaded via hotplug automatically. 2007 Install the necessary firmware files in alsa-firmware package. 2008 When no hotplug fw loader is available, you need to load the 2009 firmware via vxloader utility in alsa-tools package. 2010 2011 About capture IBL, see the description of snd-vx222 module. 2012 2013 Note: snd-vxp440 driver is merged to snd-vxpocket driver since 2014 ALSA 1.0.10. 2015 2016 The power-management is supported. 2017 2018 Module snd-ymfpci 2019 ----------------- 2020 2021 Module for Yamaha PCI chips (YMF72x, YMF74x & YMF75x). 2022 2023 mpu_port - 0x300,0x330,0x332,0x334, 0 (disable) by default, 2024 1 (auto-detect for YMF744/754 only) 2025 fm_port - 0x388,0x398,0x3a0,0x3a8, 0 (disable) by default 2026 1 (auto-detect for YMF744/754 only) 2027 joystick_port - 0x201,0x202,0x204,0x205, 0 (disable) by default, 2028 1 (auto-detect) 2029 rear_switch - enable shared rear/line-in switch (bool) 2030 2031 This module supports autoprobe and multiple chips. 2032 2033 The power-management is supported. 2034 2035 Module snd-pdaudiocf 2036 -------------------- 2037 2038 Module for Sound Core PDAudioCF sound card. 2039 2040 The power-management is supported. 2041 2042 2043AC97 Quirk Option 2044================= 2045 2046The ac97_quirk option is used to enable/override the workaround for 2047specific devices on drivers for on-board AC'97 controllers like 2048snd-intel8x0. Some hardware have swapped output pins between Master 2049and Headphone, or Surround (thanks to confusion of AC'97 2050specifications from version to version :-) 2051 2052The driver provides the auto-detection of known problematic devices, 2053but some might be unknown or wrongly detected. In such a case, pass 2054the proper value with this option. 2055 2056The following strings are accepted: 2057 - default Don't override the default setting 2058 - none Disable the quirk 2059 - hp_only Bind Master and Headphone controls as a single control 2060 - swap_hp Swap headphone and master controls 2061 - swap_surround Swap master and surround controls 2062 - ad_sharing For AD1985, turn on OMS bit and use headphone 2063 - alc_jack For ALC65x, turn on the jack sense mode 2064 - inv_eapd Inverted EAPD implementation 2065 - mute_led Bind EAPD bit for turning on/off mute LED 2066 2067For backward compatibility, the corresponding integer value -1, 0, 2068... are accepted, too. 2069 2070For example, if "Master" volume control has no effect on your device 2071but only "Headphone" does, pass ac97_quirk=hp_only module option. 2072 2073 2074Configuring Non-ISAPNP Cards 2075============================ 2076 2077When the kernel is configured with ISA-PnP support, the modules 2078supporting the isapnp cards will have module options "isapnp". 2079If this option is set, *only* the ISA-PnP devices will be probed. 2080For probing the non ISA-PnP cards, you have to pass "isapnp=0" option 2081together with the proper i/o and irq configuration. 2082 2083When the kernel is configured without ISA-PnP support, isapnp option 2084will be not built in. 2085 2086 2087Module Autoloading Support 2088========================== 2089 2090The ALSA drivers can be loaded automatically on demand by defining 2091module aliases. The string 'snd-card-%1' is requested for ALSA native 2092devices where %i is sound card number from zero to seven. 2093 2094To auto-load an ALSA driver for OSS services, define the string 2095'sound-slot-%i' where %i means the slot number for OSS, which 2096corresponds to the card index of ALSA. Usually, define this 2097as the same card module. 2098 2099An example configuration for a single emu10k1 card is like below: 2100----- /etc/modprobe.conf 2101alias snd-card-0 snd-emu10k1 2102alias sound-slot-0 snd-emu10k1 2103----- /etc/modprobe.conf 2104 2105The available number of auto-loaded sound cards depends on the module 2106option "cards_limit" of snd module. As default it's set to 1. 2107To enable the auto-loading of multiple cards, specify the number of 2108sound cards in that option. 2109 2110When multiple cards are available, it'd better to specify the index 2111number for each card via module option, too, so that the order of 2112cards is kept consistent. 2113 2114An example configuration for two sound cards is like below: 2115 2116----- /etc/modprobe.conf 2117# ALSA portion 2118options snd cards_limit=2 2119alias snd-card-0 snd-interwave 2120alias snd-card-1 snd-ens1371 2121options snd-interwave index=0 2122options snd-ens1371 index=1 2123# OSS/Free portion 2124alias sound-slot-0 snd-interwave 2125alias sound-slot-1 snd-ens1371 2126----- /etc/modprobe.conf 2127 2128In this example, the interwave card is always loaded as the first card 2129(index 0) and ens1371 as the second (index 1). 2130 2131Alternative (and new) way to fixate the slot assignment is to use 2132"slots" option of snd module. In the case above, specify like the 2133following: 2134 2135options snd slots=snd-interwave,snd-ens1371 2136 2137Then, the first slot (#0) is reserved for snd-interwave driver, and 2138the second (#1) for snd-ens1371. You can omit index option in each 2139driver if slots option is used (although you can still have them at 2140the same time as long as they don't conflict). 2141 2142The slots option is especially useful for avoiding the possible 2143hot-plugging and the resultant slot conflict. For example, in the 2144case above again, the first two slots are already reserved. If any 2145other driver (e.g. snd-usb-audio) is loaded before snd-interwave or 2146snd-ens1371, it will be assigned to the third or later slot. 2147 2148When a module name is given with '!', the slot will be given for any 2149modules but that name. For example, "slots=!snd-pcsp" will reserve 2150the first slot for any modules but snd-pcsp. 2151 2152 2153ALSA PCM devices to OSS devices mapping 2154======================================= 2155 2156/dev/snd/pcmC0D0[c|p] -> /dev/audio0 (/dev/audio) -> minor 4 2157/dev/snd/pcmC0D0[c|p] -> /dev/dsp0 (/dev/dsp) -> minor 3 2158/dev/snd/pcmC0D1[c|p] -> /dev/adsp0 (/dev/adsp) -> minor 12 2159/dev/snd/pcmC1D0[c|p] -> /dev/audio1 -> minor 4+16 = 20 2160/dev/snd/pcmC1D0[c|p] -> /dev/dsp1 -> minor 3+16 = 19 2161/dev/snd/pcmC1D1[c|p] -> /dev/adsp1 -> minor 12+16 = 28 2162/dev/snd/pcmC2D0[c|p] -> /dev/audio2 -> minor 4+32 = 36 2163/dev/snd/pcmC2D0[c|p] -> /dev/dsp2 -> minor 3+32 = 39 2164/dev/snd/pcmC2D1[c|p] -> /dev/adsp2 -> minor 12+32 = 44 2165 2166The first number from /dev/snd/pcmC{X}D{Y}[c|p] expression means 2167sound card number and second means device number. The ALSA devices 2168have either 'c' or 'p' suffix indicating the direction, capture and 2169playback, respectively. 2170 2171Please note that the device mapping above may be varied via the module 2172options of snd-pcm-oss module. 2173 2174 2175Proc interfaces (/proc/asound) 2176============================== 2177 2178/proc/asound/card#/pcm#[cp]/oss 2179------------------------------- 2180 String "erase" - erase all additional informations about OSS applications 2181 String "<app_name> <fragments> <fragment_size> [<options>]" 2182 2183 <app_name> - name of application with (higher priority) or without path 2184 <fragments> - number of fragments or zero if auto 2185 <fragment_size> - size of fragment in bytes or zero if auto 2186 <options> - optional parameters 2187 - disable the application tries to open a pcm device for 2188 this channel but does not want to use it. 2189 (Cause a bug or mmap needs) 2190 It's good for Quake etc... 2191 - direct don't use plugins 2192 - block force block mode (rvplayer) 2193 - non-block force non-block mode 2194 - whole-frag write only whole fragments (optimization affecting 2195 playback only) 2196 - no-silence do not fill silence ahead to avoid clicks 2197 - buggy-ptr Returns the whitespace blocks in GETOPTR ioctl 2198 instead of filled blocks 2199 2200 Example: echo "x11amp 128 16384" > /proc/asound/card0/pcm0p/oss 2201 echo "squake 0 0 disable" > /proc/asound/card0/pcm0c/oss 2202 echo "rvplayer 0 0 block" > /proc/asound/card0/pcm0p/oss 2203 2204 2205Early Buffer Allocation 2206======================= 2207 2208Some drivers (e.g. hdsp) require the large contiguous buffers, and 2209sometimes it's too late to find such spaces when the driver module is 2210actually loaded due to memory fragmentation. You can pre-allocate the 2211PCM buffers by loading snd-page-alloc module and write commands to its 2212proc file in prior, for example, in the early boot stage like 2213/etc/init.d/*.local scripts. 2214 2215Reading the proc file /proc/drivers/snd-page-alloc shows the current 2216usage of page allocation. In writing, you can send the following 2217commands to the snd-page-alloc driver: 2218 2219 - add VENDOR DEVICE MASK SIZE BUFFERS 2220 2221 VENDOR and DEVICE are PCI vendor and device IDs. They take 2222 integer numbers (0x prefix is needed for the hex). 2223 MASK is the PCI DMA mask. Pass 0 if not restricted. 2224 SIZE is the size of each buffer to allocate. You can pass 2225 k and m suffix for KB and MB. The max number is 16MB. 2226 BUFFERS is the number of buffers to allocate. It must be greater 2227 than 0. The max number is 4. 2228 2229 - erase 2230 2231 This will erase the all pre-allocated buffers which are not in 2232 use. 2233 2234 2235Links and Addresses 2236=================== 2237 2238 ALSA project homepage 2239 http://www.alsa-project.org 2240 2241 Kernel Bugzilla 2242 http://bugzilla.kernel.org/ 2243 2244 ALSA Developers ML 2245 mailto:alsa-devel@alsa-project.org 2246 2247 alsa-info.sh script 2248 http://www.alsa-project.org/alsa-info.sh 2249
