HP M7250N w/4G RAM, Corsair 450VX PS, Diamond Radeon HD4650 1024MB PCI-e. Windows XP Media Center

After replacing the Power Supply and Video Card (new componets specified above) there is no sound. I verified all settings specified in the trouble shooting table including volume muting, device properties, etc. I also changed the on board sound bios setting from 'auto' to 'enabled'.

The video card software added a new audio device 'ATI HD Audio rear output'. It appears to me that this new device is not being recognized. You assistance with this issue would be appreciated.

Disable and/or remove the ATI HD audio Rear output, it's for SPDIF over HDMI, you can get it back later if you need to. Milder way of action would be to try to find out where you could set your default audio device back to your onboard audio, instead of the ATI HD audio.

Here's a thread about the same issue, solved, should be helpful. http://www.tomshardware.co.uk/forum/...6101_15_0.html

Thank you for the prompt response. I was able to disable the 'ATI HD Audio rear output' and select 'Realtek HD Audio rear output'. Re-booted and now have sound! I appreciate the assistance.
