Sound on Laptop and Desktop Randomly Stops Working and Working

I fixed this (2 days without sound issue now). The trick is to completely remove flash, and reinstall it. Instruction on how to do that, are here: Uninstall Flash Player | Windows

I have the same problem here. i tried completely removing Flash and reinstalling as you said, joshowar, but I'm still having the same problem.

Any help guys??

I tried fixing it by removal, just as described in the link you provided Joshowar, and the problem still exists.

I reinstalled a clean windows 7 and still having the same issue even before installing flash\

I am starting to think it is something else

So what are the things in common here? anyone have the same parts? programs? or anything at all that may cause the problem? I have recently upgraded my pc with a motherboard and cpu. After that i got this problem and i am desperate to find a solution. I am a tech head so i have alot of things on my computer (mostly games and programs for rendering and sculpting) Ihave not found anything on my computer that can cause this. can it be a hardware issue? Just tossing ideas out there so someone might figure it out. I joined just for this issue. it is identical to mine and it messes up alot of my day when it happens.

Wanted to post this here since this was one of the top hits while googling this issue myself. Made this account to post.

I had this issue on my brand-new gaming laptop, seeming out of nowhere. Randomly the sound would stop working entirely, and if I loaded up a video on Youtube, it went about 1/4 speed. A reboot would fix this but that is not a very convenient thing.

I noticed that at one point my sound was working fine and, 30 minutes later, it stopped (while I was at my desk). The only thing that really happened of significance was that the screen had timed out and turned itself off (power saving setting). As a test, I set my laptop to never turn off the screen while plugged in.

Since I made that change, I've not had this issue occur even once again. I have no idea why it worked, or why the screen shutting off was screwing with the sound and video playback, but this is what worked for me.
