I got the amber update for my Lumia 720 and it was working fine for a day. Suddenly the mic stops working. I did not realize it until I found that there is no audio for the videos shot. Did multiple soft resets and the problem persisted. After much googling, found a reply to a suggestion in this link:

Enabled the TTY to full and the mic started working (check immediately by voice command - long press windows key) Disabled the TTY and the mic still works. Glad that it was only a software issue.
Update: The issue worsened over time and the above solution did not work many times. Took it to the service center and they replaced the mic/USB unit under warranty.

Hello guys! To solve headset and microphone issues after upgrading to WP 8, just deactivate all TTY/TDD features from Accessibility options in settings menu.
