Try to set
sysctl dev.pcm.5.play.vchanformat=s24le:4.0
sysctl dev.pcm.5.rec.vchanformat=s24le:2.0
to enable 24bit sound quality and 4 channel playback. Not many applications
support 4 channel playback though. You could use virtual_oss to split it into
two stereo pcm devices, if that's what you want.
