For snd-hda-intel, LFE volume is slave of virtual master, do it mean that pulseaudio ignore virtual master playback volume control ? Since there is no way to distinguish virtual master playback volume from those AC97 Master Playback Volume , oxygen 's multi channels master playback volume It seem that pulseaudio ignore those analog xxx playback volume controls but treat the virtual master of CA0106 as left channel only https://bugs.freedesktop.org/show_bug.cgi?id=92690 -------------- next part -------------- An HTML attachment was scrubbed...
