We're seeing on Windows 11 machines, but not all, a problem with audio output on VMIX. Not seeing on the few remaining Windows 10 machines. All are 24H2.

We're using Virtual Cable+ABCD with various outputs. This has worked well in the past.

Checked with Vlc that other apps can generate audio on the virtual bus, and pick up okay. It's just VMIX that is showing levels on the output A-D bus, but those audios don't arrive.

It looks like this is a recent problem with a Windows 11 update. Tried reinstalling VMIX with no joy. I saw this a couple of months ago, and had to completely rebuild Windows, whereafter the problem was solved, but this is not a good solution.

I can't seem to pin this down to any particular circumstance, because pretty much all the workstations use the same profile and other software.
