Core audio issues

I have a Focusrite 4PRE Thunderbolt interface and when I choose it in my audio preferences for input/output, the input will work for a few minutes and then the setting will change to AV to USB2.0 on it's own. It is interrupting my work flow and is very frustrating. Any fixes for this problem? Thanks!

Thunderbolt will no longer recognize audio interface Hi all, I recently ran into an issue with my Focusrite Clarett 8Pre X thunderbolt audio interface no longer being recognized by my iMac. The iMac is a 2015 model with no previous issues whatsoever until now. I had been running on Catalina since it shipped with no issues, but two nights ago my computer automatically updated to Catalina 10.15.6, and ever since that update, my audio interface won't show up whatsoever on my computer; not in the sound preferences, nor in the system report under hardware. Thunderbolt ports show no connections. I've tried a different cable, I've installed the latest drivers (and Focusrite control) from the Focusrite website, I've even reset SMC and PRAM multiple times. The interface turns on just fine, but the computer simply won't recognize it. I've been in contact with Focusrite Costumer support for two days at the time of this post, and they can't seem to figure out the issue either. It doesn't seem to be a hardware issue since the device is powering on just fine. I ran a system diagnostics to see if the computer had any issues with the thunderbolt ports, and everything came back clear with no issues. I'm completely lost. Please, any insight into this unfortunate dilemma would be greatly appreciated. Thanks!

Issues with Spatial audio on MacOS Monterey Is anyone else having issues turning on spatial audio on any Mac with APPLE Silicon! For some reason, it says not available and just turns on spatial stereo! Is it just me or is this an issue that others has been experiencing?
