I came across a HP DV6000 that was having an issue where the sound was not working. A re-install of the factory Vista operating system did not help and in fact the sound hardware was not even showing up in the device manager. This lead me to believe it must be a hardware problem and not a driver issue. I came across this YouTube video created by djjor3I and it was the answer I was looking for. It appears that the power ribbon also handles the sound and overtime it wears out from pushing the power button. In the video the ribbon in question is the one on the left. A new ribbon can be found cheaply on ebay, just search for “12 pin dv6000” or here on Amazon.com or if you don’t use the quick launch buttons (the ribbon on the right in the video), it is also a 12 pin ribbon and you can switch the two. Once the ribbon was replaced, the sound card was detected in device manager and once the drivers were installed, the sound worked great again!
