It didn’t take long to run into my first issue after I upgraded my Dell Latitude D620 to Windows Vista SP1 RC1. After the final reboot, my Sound Card quit working. When I noticed it, I tried to adjust my sound, but Vista told me “No Sound Device Present.”
Just for the sake of testing, I rebooted my notebook, but the problem didn’t resolve itself. Fortunately, the fix was groovy, and I didn’t even have to scrub the DELL site for new drivers.
1) Click the Windows Start Button and in the Start Search box, Type device and Press Enter Key
2) Click the Plus Sign next to the Sound, video, and game controllers category, Right Click the High Definition Audio Device and Click Uninstall
3) Click OK when confirmation box appears
4) Right Click Computer Name at the top of Device Manager and Click Scan for Hardware changes
The High Definition Audio Device should once again show your sound card, and everything should be work again.
