Bug Description

[Impact]
After upgrading the audio device firmware and doing more testing, we found some new audio issue on Lenovo P620:
1) Rear mic doesn't work.
2) Front and rear mic/line-in don't use hardware gain to control capture volume.

[Fix]
For 1), add proper PCM stream assignment to the rear microphone.
For 2), add MixerElem to let alsa-lib and PulseAudio to pick correct mixer to change HW gain.

[Test]
With the new UCM applied, rear mic starts to work, and PulseAudio can control the hardware gain.

[Regression Potential]
The system hasn't hit the market so there's no chance to regression any system in the wild.

Hello Kai-Heng, or anyone else affected,

Accepted alsa-ucm-conf into focal-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/alsa-ucm-conf/1.2.2-1ubuntu0.4 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, what testing has been performed on the package and change the tag from verification-needed-focal to verification-done-focal. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-focal. In either case, without details of your testing we will not be able to proceed.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance for helping!

N.B. The updated package will be released to -updates after the bug(s) fixed by this package have been verified and the package has been in -proposed for a minimum of 7 days.

I'd confirmed it with package from -proposed and it works as expected.

Seeing how regression-prone the changes to the audio stack are, I'm starting to think that maybe we should put additional requirements to the SRU test cases. Maybe we should always check all the possible input combinations for such SRUs? I'll have to think about it a bit.
