Windows 7: No Audio Output Device

04 Jul 2010   #1

Windows 7 64 Bit
No Audio Output Device

I have a Dell XPS M1330 with Intel Core Duo 2 and my OS is Windows 7 64 Bit. I have tried downloading drivers, windows updates, virus scans, browsed different forums for a solution, but none of them worked.. My sound just isn't working and I don't know what to do next. My SigmaTel High Definition Audio Codec is working fine, but my Intel(R) High Definition Audio HDMI is not. This is the message I get "Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source. (Code 52)"

If anyone can help I'd really appreciate it.

If thats a old computer model then there probably aren't any windows 7 drivers for it.

You could possibly search for customer drivers, or homemade drivers. However i have never used them so i wouldn't recommend it, but it could be a option.
