Only tested with snd-dummy with model=ice1712
I expect pulseaudio only use those multi channel profiles only when driver
's channel_min > 2 and channel_min equal to channel_max
So pulseaudio just playback and capture the hardware supported channels
instead of the first 4 channels
Do you mean that you want to play/capture stereo only to/from specified
jack with channel map ?
