NAME

snd_gusc - Gravis UltraSound ISA bridge device driver

SYNOPSIS

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

device sound device snd_gusc

Alternatively, to load the driver as a module at boot time, place the following line in loader.conf5:

snd_gusc_load="YES"

Non-PnP cards require the following lines in device.hints5:

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 ifconfig bridge driver allows the generic audio driver sound(4) to attach to Gravis UltraSound sound 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.

HARDWARE

The ifconfig driver supports the following sound cards:

• Gravis UltraSound MAX
• Gravis UltraSound PnP

DIAGNOSTICS
