Too Many Failures on Roon Core with Functional Zones (ref#L1VXHB)

What’s shown in the screenshot is what happens if I attempt to toggle Exclusive Mode on or off.
Restarting the core shows them as enabled again.

All DSP is off.

I had a similar problem when these same USB speakers were connect to my Core on Windows.
My Core is now on a Mac.
But in this case I can’t play via the built in Mac speakers either.
