Any idea on how to fix this?

Can you confirm the bug at bug #1063965? – Marcello Nuccio Oct 27 '12 at 11:10

remove the .pulse directory and the file called .pulse-cookie in your home folder; then you need to logout for the change to take effect.

that's the way that I use most of the time.

Good luck.

Instead of logout, you can run pkill pulse from the command line. – Marcello Nuccio Oct 27 '12 at 9:22

I used alsamixer and changed Auto-Mute Mode to Disabled

First try changing auto-mute mode to Disabled in alsamixer, if still that doesn't work, please look at a detailed solution to this at this link.
