.Dd February 17, 2007 .Dt SND_SBC 4 .Os .Sh NAME .Nm snd_sbc , .Nm snd_sb16 , .Nm snd_sb8 .Nd Creative Sound Blaster ISA and compatible bridge device driver .Sh SYNOPSIS To compile this driver into the kernel, place the following lines in your kernel configuration file: d -ragged -offset indent .Cd "device sound" .Cd "device snd_sbc" .Cd "device snd_sb16" .Cd "device snd_sb8" .Ed
p Alternatively, to load the driver as a module at boot time, place the following lines in .Xr loader.conf 5 : d -literal -offset indent snd_sbc_load="YES" snd_sb16_load="YES" snd_sb8_load="YES" .Ed
p Non-PnP cards require the following lines in .Xr device.hints 5 : d -literal -offset indent hint.sbc.0.at="isa" hint.sbc.0.port="0x220" hint.sbc.0.irq="5" hint.sbc.0.drq="1" hint.sbc.0.flags="0x15" .Ed .Sh DESCRIPTION The .Nm bridge driver allows the generic audio driver .Xr sound 4 to attach to Creative Sound Blaster ISA (mostly SB16 or SB8, known as SoundBlaster Pro) compatible audio cards.
p The value of flags specifies the secondary DMA channel. If the secondary DMA channel is C, set the flags to (C | 0x10). For a sound card without the secondary DMA channel, the flags should be set to zero. .Sh HARDWARE The .Nm driver supports the following sound cards:
