All cards (32, 32/8, 32Pro) are working identical 27 * in this mode. Rec data and play data are using the same buffer therefore. At 28 * first you have got the playing bits in the buffer and then (after playing 29 * them) they were overwitten by the captured sound of the CS8412/14. Both 30 * modes (play/record) are running harmonically hand in hand in the same buffer 31 * and you have only one start bit plus one interrupt bit to control this 32 * paired action. 33 * This is opposite to the latter rme96 where playing and capturing is totally 34 * separated and so their full duplex mode is supported by alsa (using two 35 * start bits and two interrupts for two different buffers). 36 * But due to the wrong sequence of playing and capturing ALSA shows no solved 37 * full duplex support for the rme32 at the moment. That's bad, but I'm not 38 * able to solve it. Are you motivated enough to solve this problem now? Your 39 * patch would be welcome! 40 * 41 * **************************************************************************** 42 * 43 * "The story after the long seeking" -- tiwai 44 * 45 * Ok, the situation regarding the full duplex is now improved a bit. 46 * In the fullduplex mode (given by the module parameter), the hardware buffer 47 * is split to halves for read and write directions at the DMA pointer. 48 * That is, the half above the current DMA pointer is used for write, and 49 * the half below is used for read. To mangle this strange behavior, an 50 * software intermediate buffer is introduced. This is, of course, not good 51 * from the viewpoint of the data transfer efficiency. However, this allows 52 * you to use arbitrary buffer sizes, instead of the fixed I/O buffer size. 53 * 54 * **************************************************************************** 55 */ 56 57 58#include <linux/delay.h> 59#include <linux/gfp.h> 60#include <linux/init.h> 61#include <linux/interrupt.h> 62#include <linux/pci.h> 63#include <linux/module.h> 64#include <linux/io.h> 65 66#include <sound/core.h> 67#include <sound/info.h> 68#include <sound/control.h> 69#include <sound/pcm.h> 70#include <sound/pcm_params.h> 71#include <sound/pcm-indirect.h> 72#include <sound/asoundef.h> 73#include <sound/initval.h> 74 75static int index[SNDRV_CARDS] = SNDRV_DEFAULT_IDX; /* Index 0-MAX */ 76static char *id[SNDRV_CARDS] = SNDRV_DEFAULT_STR; /* ID for this card */ 77static bool enable[SNDRV_CARDS] = SNDRV_DEFAULT_ENABLE_PNP; /* Enable this card */ 78static bool fullduplex[SNDRV_CARDS]; // = {[0 ...
