My PC sound can be off for 20 minutes but green bar is working - all of a sudden, sound comes back. Tried and checked all other settings based on on-line advice and they ok. No loose wires on pc speakers. Please help?
If it's a removable soundcard, try removing it then putting it back firmly.
If that changes nothing, or it's not removable (ie integrated), try updating the sound driver from PC manufacturer's website (if soundcard is integrated) or from soundcard manufacturer's website if it's a removable soundcard.
