Creative Pebble v3 USB-C audio issues with MacBook Pro

Just wondering whether anybody else has run into this. I've been working for about 2-3 months to diagnose audio issues on my 2019 16-inch MBP. The symptoms, which are intermittent but not infrequent, goes like this:

1. Audio output stops (audio input is fine)
2. Sound panel of System Preferences is no longer available
3. Applications that use audio output (YouTube, Vimeo, Zoom, Discord, Games) no longer start properly
4. Cannot Force Quit the application whose audio stopped working
5. Often, cannot shutdown the system other than by a hardware shutdown (pressing the power button for 10 seconds)
6. If the speakers are connected directly to the laptop instead of via my LandingZone dock...MBP crashes hard
7. Crash report for system, or debug stack for applications upon reboot after hard shutdown, always include coreaudiod and USB audio driver

This happened with Big Sur, and now it happens with Monterrey as well. Other USB speakers worked fine for 2+ years prior to me getting these Creative Pebble V3s.

I have gone through all the troubleshooting steps with Apple support (reset NVRAM/SMC, safe mode, update OS, reinstall OS, upgrade OS, etc.) to no avail. In isolating hardware components I first ran without my dock, which only changed the "sound stops" to "system crashes."

HOWEVER, disconnecting the Creative Pebble V3 has allowed me to run without problems for over a week now. So, I think i have the culprit. The questions I have are

• Has anybody tried these speakers with their MBP?
• Any other troubleshooting ideas? (there are no firmware updates for the speakers for MacOS)

I do have a ticket open with Creative, but figured that trying to attack this from both sides might help.
