# snd\_gusc(4)

Gravis UltraSound ISA bridge device driver

## NAME

**snd\_gusc** – Gravis UltraSound ISA bridge device driver

## SYNOPSIS

**device sound** **device snd\_gusc**

For non-PnP cards, add the following lines in */boot/device.hints*. **hint.gusc.0.at="isa"** **hint.gusc.0.port="0x220"** **hint.gusc.0.irq="5"** **hint.gusc.0.drq="1"** **hint.gusc.0.flags="0x13"**

## DESCRIPTION

The **snd\_gusc** bridge driver allows the generic audio drivers including [sound(4)](/sound/4.md) to attach to Gravis UltraSound sound cards.

## HARDWARE

The **snd\_gusc** driver supports the following sound cards:

- Gravis UltraSound MAX

- Gravis UltraSound PnP

## DIAGNOSTICS
