Inform userspace that one channel of the internal mic has reversed polarity, so it does not attempt to add both channels together and end up with silence.

Tested with both kernel 4.2.0-22-generic from official repos and 4.4.0-040400rc6-generic from Mainline Kernel repo. Alsa information: http://www.alsa- project.org/db/?f=3088f82a0cf977855f92af9db8ad406c04f71efa Internal microphone does not pick up sound by default. When I mute one channel, it works (this is not a good workaround since some application, such as Facebook Messenger, unmute both channels and set them to the same level automatically). Adding model=inv-dmic to snd-hda-intel module options does not change a thing. Hope that helps, tell me if you need more info.
