NAME

snd_sbc, snd_sb16, snd_sb8 —

Creative Sound Blaster ISA and compatible bridge device driver

SYNOPSIS

To compile this driver into the kernel, place the following lines in your kernel configuration file:

device sound
device snd_sbc
device snd_sb16
device snd_sb8

Alternatively, to load the driver as a module at boot time, place the following lines in loader.conf(5):

snd_sbc_load="YES"
snd_sb16_load="YES"
snd_sb8_load="YES"

Non-PnP cards require the following lines in device.hints(5):

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"

DESCRIPTION

The snd_sbc bridge driver allows the generic audio driver sound(4) to attach to Creative Sound Blaster ISA (mostly SB16 or SB8, known as SoundBlaster Pro) compatible audio cards.

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.
