The test case seems very vague sadly, could we get it a bit better clarified. What I mean is: what are the preliminary requirements for the test case to be valid? Does it have to be performed on specific hardware? What kind of hardware should it be? The regression potential field also doesn't say much about the regression potential, e.g. where possible regressions could be seen. I would appreciate if someone could update it with some regression analysis: what else can this break? Can different devices stop working by this? Which code paths are being touched by this change?

The 2nd issue of #1871329 and the 1st issue of #1881659 have the same root cause as #1875597 [Impact] On the Dell machines with multi function audio jack, after installing the ubuntu 20.04 and if the audio driver is sof instead of legacy hda, the headphone/headset can't output sound automatically after users plug in a headphone/headset. This is different from ubuntu 18.04, on the 18.04, the headphone/headset could output sound automatically after plugging in the audio jack. [Fix] The root cause is the ucm2 conf defines 2 input devices: the Mic2 and Headset MIC, and the pulseaudio parse the input device Headset MIC first then Mic2, finally the audio jack is set to Mic2 mode, this make the audio jack can't output sound anymore. To fix it, let the audio jack set to Headset MIC mode by default (Headset MIC has higher priority than Mic2 in the ucm2 conf), to do so, let pulseaudio send the device event to module-switch-on-port-available by the order of priority in the umc2. [Test Case] applying the fix patch to pulseaudio, plug a headset/headphone to the multi function audio jack, play sound from headset/headphone, the sound could be heard from headset/headphone. [Regression Risk] Low, just do a small change to store the ucm devices by their priority. and upstream just merged this patch.
