No sound on Macbook Pro, it is locked, please help
Hello everyone,
My problem is that the sound is locked. The only way to change it or to hear something is to put my headphone on my MBP.
This morning it worked, than I putted my headphones out of my MBP and the sound is now locked.
I already restarted with cmd+alt+p+r 5 or 6 times in a row.
I already searched for the com.apple.soundpref file in library/preferences, but there is no such file...
Please help me I really need my sound on something else than headphones..
thank you in advance.
MacBook Pro (15-inch, Mid 2012), OS X Mountain Lion (10.8.2)
