If I try to play a sound file or movie it wont play because I get a sound error (In windows media player I get this error: "Windows Media Player cannot play the file because there is a problem with your sound device. There might not be a sound device installed on your computer, it might be in use by another program, or it might not be functioning properly.").

When I run the diagnostics (before windows loads), it plays a song to test the system speakers. But thats before windows loads. The test tests the speakers without windows or drivers. If sound is heard, the sound card is okay and the speakers are okay. Thats how I know its a software issue and not a hardware issue. But once windows loads, I have no sound. No sound device. The only sound I get is a beep from the motherboards internal speaker.

When I goto control panel > sound and audio devices > hardware tab, it lists the Sigmatel device, but the device properties says:

Manufacturer: Sigmatel
Location: PCI Bus 0, device 31, function 5
Device status: This device vannot start (code 10)

Ive tried uninstalling the device, reinstalling drivers I just downloaded from dell.com, rebooting, system restore, and nothing works.

Still no sound. Any other ideas?
