What causes "issue_type = overload" in coreaudiod with USB audio interface?

I have a USB audio interface that is causing kernel traps and the audio output to "skip" or dropout every few seconds. This behavior occurs with a completely fresh install of Catalina as well as Big Sur with the stock Music app on a 2019 MacBook Pro 16 (full specs below).

The Console logs show coreaudiod got an error from a kernel trap, a "USB Sound assertion" in AppleUSBAudio/AppleUSBAudio-401.4/KEXT/AppleUSBAudioDevice.cpp at line 6644, and the Music app "skipping cycle due to overload."

I've added a short snippet from Console logs around the time of the audio skip/drop out. The more complete logs are at this gist:

I've also opened a Feedback Assistant ticket (FB9037528):

Does anyone know what could be causing this issue?

Thanks for any help.

Cheers,
Flux aka Andy.
