DESCRIPTION

The snd_sbc bridge driver allows the generic audio drivers

including
sound(4) to attach to Creative Sound Blaster ISA 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.
