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.conf(5):

             snd_gusc_load="YES"

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

             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 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 snd_gusc driver supports the following sound cards:

       •   Gravis UltraSound MAX
       •   Gravis UltraSound PnP

DIAGNOSTICS
