Solved Sound Randomly Stops Working

I'm using Vista, 32-Bit. Audio is Conexant High Definition SmartAudio 211, Version 4.36
HP Pavilion dv6700

When I updated my Conexant audio to 4.36, I had to reboot my laptop. The audio was working for a while, after then it randomly stopped working. I had this problem 1 month ago or so. The audio was not muted, it was enabled and it said it had no problems. I don't really know whats happening.

Any suggestions?

Roll back to the previous driver. Go to device manager,sound,conexant.Right click and go to properties. You will see the option there.

I tried that. But it doesn't work.

BTW, it randomly fixes by itself when it wants to (Started working now). I just wanted a solution for it whenever its failing.

Thanks.

Update: Now my sound says "No Audio Output Device is installed"

Update #2: I checked my Device manager on sounds, video and controllers, I don't see Conexant HD Audio. I used recovery manager, nothing happened. I uninstalled the driver, it didn't reinstalled. But when I did it before, it reinstalled and worked for 5 minutes. I basically did almost everything to fix it, I might have missed something, but please help me. I'm getting so annoyed by this.

Found the problem to my sound.

It was the Service Pack 2 that stopped my sound from working, I tried methods from the Windows/Microsoft site (Method 1-7) none work.

It was the Service Pack 2's problem.

Thanks for helping out guys!

(And tell me how to put this into the "Solved" thing)
Please and Thank you.
