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: .Pp .Bl -bullet -compact .It Gravis UltraSound MAX .It Gravis UltraSound PnP .El .Sh DIAGNOSTICS .Bl -diag .It xxx: gus pcm not attached, out of memory There are not enough memory to drive the device. .El .Sh SEE ALSO .Xr sound 4 .Sh HISTORY The .Nm device driver first appeared in .Fx 4.0 . .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.
