Vista audio crackle - just a note...
I have a D810 with Vista and there is no "crackle pop" audio problems.
I loaded a blank copy of vista with no drivers on my Studio 17 and loaded the wireless drivers and experienced the "crackle pop" audio problems.
So it must be something with newer laptops hardware since I basically had nothing but Vista loaded.
Studio 17 laptop:
I had a DVD Vista didn't like.
It locked up my PC.Windows Audio service had to be restarted.
Never seen that on XP.
Maybe someone can mess with placing the Windows Audio and the Windows Audio Endpoint Builder into it's own svchost process.
I tried but wasn't successful in getting the sound to work anymore, so I set the registry keys back (from a backed up .reg files)

Thanks for sharing that. Every bit of information helps.
A huge difference between the D810 and all of the models that have the noise problem is that the D810's motherboard followed Intel's AC97 audio protocol. I really think that the models with Sigmatel STAC 975X (AC97 compliant) had fewer problems than the newer ones. But 2-3 years ago the protocol was upgraded to the current HD (high definition) codec, and so all of the motherboards required audio chips with that specification. For the most part Dell uses the Sigmatel 92xxHD chips to meet the requirement. They have drivers with less functionality than the AC97 ones, but other than that seemed to work okay in XP. When Vista came out the posts here about the noise increased dramatically. Most of the problems seem to be on models with a combination of HD chips, Vista OS, wireless, and perhaps video drivers are involved.
