sound distortion after sleep/standby


Honorable Member
When I bring my Windows 7 Home Premium desktop out of sleep or hibernation, all the normal system sounds play in a distorted manner. If I reboot, then the sounds play normally. I have an on board 5.1 HD 6 channel audio codec and have removed the driver, then got Win 7 to find the latest driver (Microsoft) but that makes no difference.
On my purchase order details I find:
Microsoft UAA Function Driver for High Definition Audio Adi 1986. If I try to play anything in my media folder all I get is a distorted hiss, I can't detect any 'music' at all.
I don't have a spare PCI slot to fit a sound card so I would like to find the reason for this on board audio problem but not sure what to do next!
any pointers would be great.

I had this problem recently and found (somewhere) a workaround of stopping then re-starting the AudioEndpointBuilder service.
I made this four-line batch file which does the job

net stop audioSrv
net stop AudioEndpointBuilder
net start audioSrv
net start AudioEndpointBuilder

Hopefully useful to others, even years after the original post.

Thank you so much for updating your post with the answer, even after all these years. I am having the exact same problem and your solution works perfectly!
