Audio Stutters and Buzzing Caused by DPC Latency
So, I downloaded LatencyMon as stated in threads concerning people with my same problem. The closest I got to finding someone with my same problem was when they were having problems with usb.sys or something or other, can't recall the exact filename. What makes my predicament tricky, or so I think, is that the problem is being caused by what seems to be a binary file within System32\drivers named DDDriver64Dcsa.sys and another was ACPI.sys, the former having the highest DPC routine execution time (501188) and the latter having the highest ISR routine execution time. (82.5)
From what I'm reading, I'm interpreting it that DDDriver64Dcsa.sys is the cause of my problems. I've disabled ACPI.sys and it has had no effect on the audio stutters. The good thing is that I know what to try next, the bad thing is that I don't know what to do with this other file. It is a binary file within some other package. Systemexplorer.net has it that "This file belongs to product Dell Diags Device Driver and was developed by company Dell Computer Corporation. This file has description DDDriver.sys." I'm a bit scared to just up and delete it, as I'm not entirely sure what it does.
