Very interesting! So you start up the CPU stress benchmark test, and then start up Cantabile and Voicemeeter while that is running, and then turn the benchmark program off and it leaves everything fine? I’ve GOT to try that!
I noticed another thing. For the first time, I needed to do some processing using the 96000 sample rate going out of the machine’s own headphone jack, so I carefully set all the items to 96000 (Voicemeeter, Realtek card, Cantabile), but was getting intermittent clicks that seemed to doom the setup. That is, UNTIL I went into Cantabile and checked the “Double Buffering” check box on the audio engine page in Options. It went away and never came back! So, there is another trick for ya.
