Onboard audio problems G1.Sniper.M5

Ok guys, this mobo has been running perfectly for a few months now. Just now though i was playing BF4, the sound went super high pitched and all the bass disappeared ended in a whining noise and then i shut down my computer. When it booted up again, i got an error "No Audio devices enabled". I've tried to re-install the drivers but they cant find "compatible hardware"... Did my audio die? Maybe it's the op-amp? Any suggestions until i can get a hold of gigabyte support during the week?

Maybe try to replace the replaceable op-amps on the motherboard? This motherboard comes with replaceable op-amps for occasions not like this, but still, give it a try.
