[Bug 271559] [sound] [snd_uaudio] Creative Katana V2X garbled audio

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=271559

--- Comment #13 from Hans Petter Selasky <hselasky@FreeBSD.org> ---
It depends how your speakers are connected.

The virtual OSS needs 6 mix channels, or 8, if you want to use the "-M" option.

Also install the QT control panel for virtual_oss.

Then you can create one /dev/dsp for 2 channels only.
Then you can create one /dev/dspXXX for 6 channels. VLC can use this for video.

virtual_oss has a "-M o," option which can repeat a channel to another output
channel. You can also create virtual channels, that are not output, to have
multiple configurations. Like /dev/dsp sends to channel 5 an 6 (via -m 5,6)
(channels start at 0 currently). Then channel 5 and 6 are distributed to
channel 0..4, like this:

-M o,5,0,0,0,0 
-M o,6,1,0,0,0 

Did that make sense?
