The headphone/headset should be able to output sound automatically after plugging in the audio jack. [Test Case] * On Tiger Lake platform Reproduce step: 1. plug headphone/headset 2. open g-c-c sound to check Expect result: The output device should switch to headphone or headset, since headphone's priority is higher in ucm2 config. Actual result: The output device is still internal speaker. [Regression Potential] * The change insert the ucm device by its priority, the potential regression is low, since if the change is not working properly, the side effect is that the order of ucm devices are wrong, and it won't switch to the correct output device as expect, but user can still config it manually. [Other] * This bug originates from an OEM private bug #1875597, then ubuntu users reported 2 public bugs #1871329 and #1881659. The 2nd issue of #1871329 and the 1st issue of #1881659 have the same root cause as #1875597 * 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.
