HD graphics card killed my audio.
Just upgraded to an ATI Sapphire HD 4670 512MB vid card, from an ATI Sapphire X1550 256MB.
I installed the card and the drivers from the provided disc. I plugged everything in an booted up, everything worked. Except sound.
Now my sound icon in the system tray has a red X on it and Windows troubleshoots it when I click it, to no avail. There are now no sound devices detected, except HDMI HD Audio Device, which reads as unplugged. I'm not using the HDMI on my graphics card at the moment, or for a while to come. No matter what is plugged in, the HDMI device is the only detected device. I still have my NVidea Realtek HD Audio drivers installed. I tried uninstalling and reinstalling, uninstalling the ATI software, and still the HDMI audio device is the only one detected. Even plugging into the headphones jack gives me nothing.
Halp plx.
