I'm having a truly annoying issue. I swapped the 5850 in my htpc for a 6950... Uninstalled the old drivers before installing the newer card, all the usual stuff you try to do cleanly when you upgrade. With the 5850, everything was perfect. With the 6950, the speaker configuration lights that come up on the Yamaha display keep blinking, sometimes producing a slight clicking noise. That's if I'm just browsing the net, sitting on desktop, or otherwise not playing music/video/games. If I have a movie or a game on, the sound is right as rain. Also, windows seems to be forgetting the speaker configuration between system restarts. Has anyone heard of a similar issue or a way to fix it?
