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: the header is pinned in the constructor. See the following code: ``` hHeader = GCHandle.Alloc(header, GCHandleType.Pinned); ```
