DynamicD:
For your information, under Vista, I was able to have sound over HDMI with the Catalyst 8.2 already. However, after upgrading to Windows 7-32 bit with (i.e., included in Windows 7
drivers) ATI
drivers or ATI V9.11, I cannot get the same result. I uninstalled the new
drivers and re-installed the Catalyst 8.2
driver. It worked for 1 day and an intermittent problem cropped up. What I did was I reinstalled the ATI 8.2
driver with "custom mode" with only basic
driver with no System Tray ATI Catalyst or Steam software at all. It started to work again more reliably. *Yes, I am familiar with that icon indicating the device was not plugged in. Some folks have mentioned that you might right click to enable it. I am not sure. Note: I typically don't connect my PC over HDMI all the time. Only when I want to watch Blu Ray or some other online resources. I know I have to play around with the driver setting to get my Samsung LN40B610 40" TV to work with the ATI. The 8.2 driver always the one that works! Good luck!
