Commented Unassigned: Occasional AccessViolation in WDMAUD.DRV [16396]

Under load, I am getting an occasional AccessViolation in WDMAUD.DRV, and my application is crashing.

Comments: I haven't got a 'stand alone' piece of code that reproduces this issue yet - Still working on producing a smaller test harness that produces the same result. However, the stack trace from exception is as follows: 0:000> !pe Exception object: 00f8dbd4 Exception type: System.AccessViolationException Message: Attempted to read or write protected memory. This is often an indication that other memory is corrupt.
