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.
