Comment 68 for bug 874535

My issue was due to a bad jack detection.

You should try the following:
Install alsa-tools 1.0.28-1 (1.0.28-2 if the previous is not working)
run hdajackretask
Tic Advanced override
Set Jack detection to Not Present for the jock you have the issue.
Clic Apply now
Clic Install boot override and reboot

I had to set headphone and front mic on my box
Hope this will help
