p For non-PnP cards, add the following lines in
a /boot/device.hints . .Cd hint.gusc.0.at="isa" .Cd hint.gusc.0.port="0x220" .Cd hint.gusc.0.irq="5" .Cd hint.gusc.0.drq="1" .Cd hint.gusc.0.flags="0x13" .Sh DESCRIPTION The .Nm bridge driver allows the generic audio drivers including .Xr pcm 4 to attach to the following ISA sound cards: l -bullet -width 2m t Gravis UltraSound PnP t Gravis UltraSound MAX .El
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 DIAGNOSTICS l -diag t xxx: gus pcm not attached, out of memory There are not enough memory to drive the device. .El .Sh HISTORY The .Nm device driver first appeared in .Fx 4.0 . .Sh SEE ALSO .Xr pcm 4 .Sh AUTHORS .An Ville-Pertti Keinonen Aq will@iki.fi .An Seigo Tanimura Aq tanimura@r.dl.itc.u-tokyo.ac.jp .Sh BUGS Recording pcm sound data is not supported yet.
