I'm not sure if this is the correct place to ask this but here goes. I have a HD 6870 card and have my normal monitor hooked up and then an HDMI cable running to my TV. Basically what I like doing is streaming Netflix off to my TV (or DvD's etc). When I extend my desktop to include the TV, the video is fine, but I have no sound. When I go to sound playback options the TV shows as "not plugged in" and sound obviously doesn't work. However after a reboot, all is fine and sound works. It's a pain having to reboot every time before I can stream off to my TV. Any ideas?
