Unfortunately, it is "available" if there is something plugged in and "mot available" if there is nothing plugged in. > Should changes in "channel mode" , "Headphone Mic jack mode" or "Mic Jack > Mode" trigger an event so that pulseaudio server probe the sound card again > ? Changes in "channel mode" do not trigger anything that pulseaudio -vvv considers loggable. Changes from 8ch to 6ch do not cause the 7.1 profiles to disappear. The device has no controls that contain "mic jack mode" as a substring and are controllable via alsamixer. -- Alexander E. Patrakov
