** Description changed: - After backporting following patches from PA and alsa-ucm-conf and then - it works. + == SRU Justification == + [Impact] + On P620, only single port can work on rear panel. 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.
