.Dd December 15, 2005 .Dt SND_GUSC 4 .Os .Sh NAME .Nm snd_gusc .Nd Gravis UltraSound ISA bridge device driver .Sh SYNOPSIS To compile this driver into the kernel, place the following lines in your kernel configuration file: d -ragged -offset indent .Cd "device sound" .Cd "device snd_gusc" .Ed
p Alternatively, to load the driver as a module at boot time, place the following line in .Xr loader.conf 5 : d -literal -offset indent snd_gusc_load="YES" .Ed
p Non-PnP cards require the following lines in .Xr device.hints 5 : d -literal -offset indent 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" .Ed .Sh DESCRIPTION The .Nm bridge driver allows the generic audio drivers including .Xr sound 4 to attach to Gravis UltraSound sound cards.
p 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. .Sh HARDWARE The .Nm driver supports the following sound cards:
