I've got a big problem with my x51v: I've lost all the sounds (both system and multimedia ones)!
It's not the settings>sounds¬ifications, 'cause the boxes are all ticked, and with my earphones I hear everything...
I have just tried with a hard-reset, but... it's still mute!
Is there any setting for a "earphones out" to deactivate (even if I think the hard-reset should have solved this)? Any idea?
