Incorrect or no sound output selected
I have Windows 7 Ultimate x64 and an AMD graphics card with HDMI connection for sound and graphics.
HDMI is connected to my Marantz amplifier, just as my tv decoder and my BD player. A single HDMI cable is connected to my TV, so my amp decides which source is displayed on the TV.
Since a while, when I switch on my PC, the audio output is automatically set to the onboard Realtek audio output. However, this is audio only, so I need the AMD Audio on the video board, to which the HDMI is connected. Windows Sounds in the Control Panel indicates that the AMD output is not connected. When I unplug and plug the HDMI cable it selects the correct output. This happens every time I switch on the PC. I already updated the drivers and Catalyst, no luck.
I disabled the Realtek audio outputs, and all analog outputs. Now when I switch on the PC, no output is selected. When I unplug and plug the cable it detects the correct HDMI connection.
A friend of mine uses the onboard HDMI connection with Intel Display Audio driver, and has exactly the same problem.
