Realtek HD Audio not working

[corcinn]

ok, here it is. Two days ago, I stated up my laptop from sleep mode and the sound was not working. The drivers say they are functioning, but seem to be in use and unavailable. I have had the laptop for five months and it has been working fine. I tried to check what might have taken place in the mean time between closing it and booting the system again. What I found was that there had been a restore point made shortly after I booted the system for an automatic update that didn't actually get installed. So I restored the system back before that, and tried several different points up to a month ago with no luck. I've downloaded newer drivers. Tried different driver versions, the official developer downloads and the Realtek downloads. I just installed SP1 as well, and then re-tried it again. I've tried to check for every mal-ware, virus, trojan, and anything else I could think of. I am at a complete loss for what to try.
Thanks in advance for any help I can get.

The sound controller imbedded on the motherboard might have gone bad

 

[corcinn]

And how would I go about testing that?

"And how would I go about testing that?"...

By replacing the laptops motherboard. A cheaper alternative might be to buy an external USB sound device

Please uninstall and reinstall your mobo / audio drivers. You should have sound again, I bet its greyed out in the audio properties as no sound detectied. Simply you can even install from MOBO cd, I recommend you do that... GL champ,

Possibly the Microsoft UAA driver is not installed correctly. If you go to system then select "show all devices" find the uaa driver and if it has a question mark, remove it and reboot . This should fix it if its your problem.
