Re: Compaq Presario V6000 - No Sound Device Installed Error

Hi corbetta, welcome to the HP Forums. I have included 2 documents to help you resolve the issue. The first one seems more specific to the issue you are having, I recommend following all the steps from the top down (even though you are on SP2). Audio Stops Working After Installing Windows Vista Service Pack 1 (SP1)

If that fails, regardless of the title, these steps are perfect for the issue you are experiencing. Resolving No Sound or Audio Problems (Windows Vista)

Let me know if this helps.
