There's a view in the Scheduler dataset called Thread Priority variation on Time which shows changes in the priority assigned to processes. The older traces show quite a few changes to the audiodg.exe process throughout. The latest trace shows only 4. One at about the 7 second mark, another at second 22.5, another at second 24.5, and a big drop at second 26. Do you recall if that was more or less the pattern to the pops during the latest trace?
