I just tried that, but in the control panel there is only the default device of the ATI HD rear aduio output for under the heading sound playback. Did maybe installing this card completely over ride the other outputs/erase it?? Could it be something became unplugged on the inside as I installed the new graphics card? Any suggestions/help is greatly appreciated
Odd...the ATI cards have their own audio output, but they shouldn't cause any conflict with the existing sound drivers...
You could try re-installing your motherboards audio drivers again, then checking the control panel to see if the output is selectable. Also, check your BIOS to make sure that your onboard audio is enabled.
Power down your system and uninstall the graphics card. If your new graphics card replaced an older ATI card, reinstall that, or use on-board graphics. Power the system back up and check to see if the old sound devices show back up.
