Rear Mic on Lenovo P620 cannot record after S3, despite that there's no error and the other two functions of the USB audio, Line In and Line Out, work just fine.
The mic starts to work again after running userspace app like "alsactl store". Following the lead, the evidence shows that as soon as connector status is queried, the mic can work again.
So also check connector value on resume to "wake up" the USB audio to make it functional.
This can be device specific, however I think this generic approach may benefit more than one device.
Now the resume callback checks connector, and a new callback, reset_resume, to also restore switches and volumes.
