Default [Q] Bottom mic stops working after a while

Hello,

I know this topic may sound similar to people around, although after long search I haven't found solution to my problem, which persists. Two weeks ago my bottom mic stopped working out of nothing and I have no idea why. I am currently running Cyanogenmod 11- M5 snapshot. Here is what I tried:

- Different ROM (Omni)
- hawkerscripts to full wipe
- take out / enlarge the hole of rubber covering the bottom mic inside
- amplify the gain through several applications
- disable noise reduction

Problem is it seems software related, because after a reflashing of cyanogen this evening, during first call the other side could hear me normally, but after a while of idleness (an hour) the mic stopped working again (e.g. I cant record sound in app or call). Only top speaker works which sucks.
Thank you for your advices
