So I couldn't find anything specific to this in the forums so I'm writing to see if anyone can solve it.
As of last night, my computer headphone jack worked perfectly.
today I plugged the headphones (which work in other devices) and no sound. The computer recognises something being plugged into the jack but there's no sound coming out of it.
The volume is on, the inside speakers work, and there is the crackling from plugging the headphones into the jack... but there isn't any sound coming out it.
I tried reinstalling the driver, restarting the computer and nothing has changed...
