Hi guys! It seems to be the only forum where members really helps to solve that kind of problem.
As many on this forum, i also have a audio glitch trouble. I see glitch in reports but cannot solve this.
Main trouble: Audio glitches occuring frequently when i started my virtual machines on my Windows 10 Hyper-V Host. When all VMs are stopped, i don't hear any glitches and so on.
Also, in all reports i see USBPORT.sys. Probably, it is linked with Hyper-V functions. But the main reason in Hyper-V drivers\buses etc. And i don't know how mitigate this.
I used xperf, Windows Performance Recorder (WindowsXRAY FULL TH Power Performance mode) + Media eXperience Alanyzer and LatencyMon also.
Logs: xperf with glitch, WPR with glitch, another WPR log with glitch
in MXA i also see audio glitch (and video glitch also) but can't narrow down the issue.
It seems that all threads are stopped before glitch, even system:

LatencyMon showed me that i had a big troubles before updates. After i updated Win10 to latest update and all drivers to its latest versions, LatencyMon no longer shows me that i have a troubles.
But glitches still occurring frequently (a couple of times in 1 minite).

[TD]Your system seems to be having difficulty handling real-time audio and other tasks. You may experience drop outs, clicks or pops due to buffer underruns. One or more DPC routines that belong to a driver running in your system appear to be executing for too long. At least one detected problem appears to be network related. In case you are using a WLAN adapter, try disabling it to get better results. One problem may be related to power management, disable CPU throttling settings in Control Panel and BIOS setup. Check for BIOS updates. [/TD]
