I swapped my previous PSU since it had failed. I've been having this issue since then. I boot up the computer, start watching a video, after a few minutes the audio goes off completely and I start hearing that whizzing noise, though it's very quiet.
 
I've tried reinstalling the audio driver. Didn't help.
Updated GPU driver just in case, didn't help.
Tried other audio devices, didn't help.
I also made sure I was using the correct rear port.

I don't know what to do, I'm at a loss here. Any help would be appreciated. Thanks!
