I'm having an issue with maintaining HDMI audio after cycling receiver/tv power. The PC thinks it has no HDMI audio connection and disables the device. I'll have video but no audio. If I open the sound properties the PC detects the HDMI connection and reactivates. I didn't used to have this problem. I believe an upgrade Catalyst driver introduced the problem.
I've tried 11.11, 11.10, 11.9 and now 11.8 and they all have the same issue (I use driver sweeper to clean between each install). Does anyone else experience this? What driver version is working for you?
My setup is:
I have the PC stay on 24/7. I've tried keeping the video card on and letting it go standby - both exhibit the issue.
