Windows 7 RC 64 USB Audio Jitter/distort issue

Changing power settings worked for me.

Changing CPU throttling doesn't help me out one bit. My issue is with DPC spikes. The primary culprit is my Arteros AR94285 Wi-Fi card. They have some patched drivers that helped out a bit about half of the audio dropouts stop but its very noticeable still. The secondary culprit is the Windows battery polling service. Disabling these fix the bulk of the spikes but something else is still spiking. Windows 7 sure does do a lousy job of allocating which CPU core is handling DPC tasks. You can have 8 cores and it can't even play one audio stream. Errrrrrr!!!!!!!
