--- Comment #6 from Andrey Zholos <aaz at q-fu.com> ---
ioctl SNDCTL_DSP_CHANNELS sets the number of channels in the
current stream. E.g. mplayer -ao oss -channels 6 does this.

For this to work either virtual channels have to be disabled
(sysctl dev.pcm.4.play.vchans=0) or their format set correctly
(sysctl dev.pcm.4.play.vchanformat=s16le:7.1).

Some applications support PulseAudio but not OSS - that's one important
benefit :)
