Latest follow-up on my experience…
I was able to get PortAudio audio system working with VB AudioCable when launching wfview weekly build 20221001-11-24-08. VB Audio Cable was 4th in the audio output pull-down list, so that got me thinking if the problem happened only for the 1st entry in the pull-down list. I describe an experiment below. Interesting results - always a problem when launching wfview with the first item in the Audio Output list for each Audio System.
This behavior is reproducible for me, so I hope it is for others, too, to identify and resolve the problem.
Best,
Ron
