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 ? https://bugs.freedesktop.org/show_bug.cgi?id=89541 -------------- next part -------------- An HTML attachment was scrubbed...
