I tried all the drivers I could find but gave up on trying to get the on board sound working properly on my P5B Deluxe. I was looking for S/PDIF out but the problems included the volume going up and down at random, missing bass and static noise similar to a $5 radio. Very disappointing but it overclocks like crazy so I threw in a sound card and saved my sanity for more important things.
I know AUTO for core voltage on the P5B is scary. AUTO is giving me 1.576 volts for the core at idle which is right at the Intel maximum of 1.55 volts under load.
Here's a beta version of CPUz that seems to finally support the correct display of core voltage.
