# snd\_sbc(4)

Creative Sound Blaster ISA and compatible bridge device driver

## NAME

**snd\_sbc** – Creative Sound Blaster ISA and compatible bridge device driver

## SYNOPSIS

**device sound** **device snd\_sbc**

Non-PnP cards require the following lines in */boot/device.hints*: **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 drivers including [sound(4)](/sound/4.md) 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.

- Avance Asound 110
