Fixing the channel maps would be good, but I don't think pulseaudio cares much about them, at least if the override-map options are set for the elements. As I said in my previous mail, pulseaudio doesn't recognize these new element names, but the necessary configuration can be added pretty easily. /usr/share/pulseaudio/alsa-mixer/paths/analog- output.conf.common contains the "PCM" element definition, so these new elements should be specified in the same file. You can see in analog- output-lineout.conf how we configure the override-map options for the "Front", "Rear", "Center" and "LFE" elements, and you should be able to simply copy those to the new "PCM Front", "PCM Rear" etc. elements. -- Tanu https://www.patreon.com/tanuk
