I get this error after installing new updates. This is the output of VLC:

I get similar errors from Gmusicbrowser as well. I tried the solution suggested here without avail. Reinstalled VLC, Alsa and Pulse Audio but again no help.
Reinstalled Ubuntu after spending so much times looking for a solution.
