5770 Audio Problems

[jpsteinmetz]

Hello everyone,

I just got a new XFX 5770 for my HTPC. I'm running Windows 7 Pro 32-bit and have installed the 10.1 drivers. I'm using the HDMI connector to my AVR having it set for 5.1 24/192 output.

Unfortunately when I run Media Center I get static from various speakers and then odd channel switching behavior where what was on the front left/right channels switches to the back and so on. Everything is fairly random. If that doesn't happen then I usually end up with a 2 second loop of whatever audio was first played in the file. Video playback is smooth at all times. Finally after several seconds I usually get the "Video Error: Please restart Media Center or your computer" message.

What's more odd is that if I play the same file in Windows Media Player I get perfect playback.

I have tried doing a complete uninstall and reinstall of the driver, i've used 9.12 drivers, and have even tried disabling all other onboard audio/video devices. This is an entirely fresh install of Windows.

Has anyone heard of or seen this issue before? Do I have a bad video card?

I had issues initially setting up my 5770 in my htpc. Took me a bit of research but I now have it working correctly.

Found my answer in installing the current ATI CCC (Catalyst Control Center suite) drivers witout the HDMI driver. Then I went to RealTek and installed their ATI specific version of the HDMI driver. After that I installed a custom EDID driver created by Tulli (a guy in that thread). I have no issues with my card at all anymore on my HTPC.

I was having serious handshake issues where my screen would flicker on and off and my audio would drop out and static.

Here is the thread that helped me:

Hope it helps you. Great card for the HTPC once you get functioning correctly.
