After upgrading from 12.3 to 13.1, the headphone becomes silent while the speaker works fine. Tried several different solutions. Then found this solution.

I just found out how to make my headphone work, really simple, only two steps:
*ATTENTION* reboot won’t work. only boot after a shutdown can make it work. no matter if I reboot from Ubuntu or Windows 7, My Headphone never works. but if I shutdown from Ubuntu or WIndows 7, then boot into Ubuntu, my headphone will work perfectly.
Well, I really don’t know why. Anyone knows how this works, please send me an e-mail, I’ll be appreciate ^ ^ !
