So, first of all, most of high CPU interrupt events cause the sound to spike ever so often. It seems mine doesn't, it just makes my computer run slower than usual. I've been reading this thread to figure out if any info would be of use, but came to think, my problem might lie somewhere else. I'll attach the xperf output file, the resource monitor screenshot and a dpc latency checker screenshot. Any ideas/help would be of great use. Res mon screenshot: Latency mon ss: DPC latency checker: And xperf interrupt summary table I would've uploaded the .etl file but it's kind of large . Any ideas ?
