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.

[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.
