Latency, latency everywhere. Anything related to audio has severe distortion, pops and lag spikes which also affects video in-game, believe it or not. Now, as I said, LatencyMon was kind enough to point out USBPORT.sys as being the intruding thorn and have actually narrowed down / part fixed the issue.

High DPC Latency caused by USBPORT.SYS in Sound & Audio. I've been having trouble recently with audio clicking and popping, and I've traced it to high DPC latency caused by USBPORT.SYS, mostly during periods of high CPU usage but it also just seems to worsen over time. I've tried disabling non-core drivers one by one to attempt to find the ...

About the VB audio bridge, I didn't notice any improvements in USBPORT.sys and it also introduced an unbearable audio delay in my games, about a half second delay, even when using the lowest possible buffer size. It worked fine when listening to music through foobar but I don't think it's usable in games at all.

When I turn the polling rate down to 500 Hz, CPU usage still spikes up to around 8%. When I look at LatencyMon while moving my mouse around on the desktop I can see ISR count, DPC count, and total execution time skyrocket for usbport.sys. TL;DR: usbport.sys is being a cunt and won't go away. Please advise.

So I'm having kind of the same problems as you do (with a Roland Octa Capture, though) and no solution. Interestingly, I do not have audio crackles when LatencyMon is monitoring.
