[Bug 1519304] [NEW] Microphone not working

 

You have been subscribed to a public bug:

Sound settings -> Input controls are grayed out.  Alsamixer's mic is
unmuted yet I can't record anything from Internal mic or using earphone
jack.

I tried upgrading kernel to 4.3 from http://kernel.ubuntu.com/~kernel-
ppa/mainline/ and it still doesn't work.

Willing to debug this.  Just need some pointers.
