I just built a machine with the parts listed below.  Runs fine Blu-Ray looks
GREAT.  Problem is audio drop outs on Blu-Ray playback and when playing
lossless WMA across the wireless.

BIOS and all drivers are newest on the web.  I've tried disabling everything
in the device manager one at a time.  Removed memory and tried one stick at
time.  Ran dpclat.exe and it shows DPC latency average 1200 with spikes up to
2000.  Seems like if I do anything to cause HD activity it spikes.

Any ideas on what to try or a better place to ask?

Thanks
