AMD Publishes Catalyst 12.6 WHQL Driver
AMD has updated its Catalyst graphics driver suite to version 12.6.
The software includes the display driver 8.98, HydraVision for Windows Vista and Windows 7, the Southbridge/IXP driver, as well as the Catalyst Control center 8.98 and Vision Engine Control Center 8.98. The package is compatible with 5600-series desktop cards and up, 5100-series mobile chips (and up) as well as FireStream versions 9170 (and up).
According to the release notes the graphics driver has been updated "to provide enhanced level of power, performance, and reliability." APUs that are combined with discrete graphics cards receive new dual-graphics DX9 application profiles in Diablo 3, Elder Scrolls: Skyrim, StarCraft 2, Portal 2, Call of Duty Modern Warfare, and Call of Duty Black Ops.
Also included in the 12.6 release are 11 fixes that cover a "possible" video driver vulnerability issue, system crashes and hangs, as well as a video corruption problem. The driver can be downloaded from the AMD site.

I am so happy to hear someone else has a similar issue. If I had known this would happen I would not have sold my 6850 to my coworker and upgrade to a 7850. So annoying to unplug and plug back in the hdmi cable every time I turn the TV back on.
HDMI with AMD is a complete mess... Have to go DVI and a 3.5mm sound cord...
Well look at that, it is. Thanks for the call out.
Cancel that. Upon further digging into the release notes, it is NOT the official driver for HD7xxxM card, but the 12.7 beta driver is.
12.6 Release Notes
12.7 Beta Driver Notes
It also happens with Nvidia's GTX 580 it's not only an AMD problem.
Its a driver issue, not a GPU model issue. My HD5450 had the same issue on 12.4 drivers on my HTPC. try the 12.6 (which are supposed to fix it) and if not, I know the 12.3s didn't have the issue.
Oops, forgot to include the fact it was the sound issue haha
Talk about using old, unoptimized drivers.
I think got same problem.
Everytime i install 12.6, I always get an Error Report at the end of installation.
HDMI/DP Audio Driver Installation Fails.
I tried everything.. Driver Sweeper, uninstalled realtek audio driver and updated Windows 7. It's still like that. I thought it was my GPU.
Never had this problem back in 12.4 and i've tried 12.7 Beta, I never get a problem like that.
It's just the fkn driver.
Since i don't use HDMI port, I think it's ok to me but to others; i think No.
anyway this version has slight improvements,
but 12.7 =has got some reasonable improvements,
would like to get 12.7 in stable form
but the word "beta" worries me..
