Hi Steve,

I'm not familiar with the problem that you are describing. Sorry! Here are a few resources that I hope are helpful:

Please let me know if the 2 resources above didn't help you resolve the issue, and I'll do some more digging for you.

I'm having the same exact issue. It tells me that the tv sound (AMD HDMI output) is unplugged. Tried everything you did, even a recovery, and nothing worked. Running a 6770 though.

EDIT: Fixed now. Kind of feel like an a55hat. Unplugged everything and replugged it, also used a different HDMI port on the tv.

EDIT #2: This was a temporary fix. It has to be redone every 12 hours or so because it bugs out again with the same issue.

I'm having the same issue. I only just got around to installing the update today and it killed my sound. I run a 6770 through the TV over HDMI, picture still works but sound is dead. I can see 'AMD HDMI Output' under my audio devices but windows 7 thinks it isn't plugged in.

When I got this computer I didn't have any sound and had to instal a generic Realtek driver to get it working, is this just a flaw with the AMD drivers when combined with something else that happens to be on my system?


That sound very frustrating.

Try contact AMD support either by email ( or by phone ( This appears to be an issue that AMD support can help you with.
