For example, when the Line-Out is plugged, the Mic won't work anymore. [Fix] Use upstream version of UCM to handle port priority correctly, instead of separate ports into different profiles. [Test] Once the UCM is in place, all three ports of rear panel work correctly. [Where problems could occur] UCM is not a static thing - it's actually interpreted differently at higher level. So any change in userspace daemons other than PulseAudio may not like the change and can interpret the UCM in another way. == Original Bug Report == After backporting following patches from PA and alsa-ucm-conf and then it works. https://gitlab.freedesktop.org/pulseaudio/pulseaudio/-/merge_requests/290 https://gitlab.freedesktop.org/pulseaudio/pulseaudio/-/merge_requests/354 https://gitlab.freedesktop.org/pulseaudio/pulseaudio/-/merge_requests/355 https://github.com/alsa-project/alsa-ucm-conf/tree/master/ucm2/USB- Audio [landed by aa74f4c12eefcc98582572d2fc48982cf7478b51] Here is the test PPA: https://launchpad.net/~os369510/+archive/ubuntu/oem-package-test Since the upstream not yet accepted those patches, the regression potential may quite high.
