Hello, I recently bought a Sapphire hd4890 and was briefly able to use the card's built in audio function via an hdmi cable to my television. I stopped for roughly a week and when I next tried to use the sound again, it didn't work. Within that period of time, I installed some Realtek drivers for my audio so I could have that cool function where when a new device is plugged in, it is detected and a menu comes up. This shouldn't pose any problem with my previous setup explained though, should it? When I right click the volume function in the Quick Launch area, and go to "Playback Devices", I am able to see my ATI High Definition Audio Device (with a picture of my television) but it says below, that it is not plugged in (im running windows 7 if that offers any help). Thanks to anyone who can lend a helpful tip in my strange predicament.
