Pro Tools Playback Issue on M1 Mac Mini - Audio Dropouts Every 15 sec

[DEliker]

Hoping someone has an idea about this but I don't see any other post on it.

Testing a new 2020 Mac Mini M1 with Monterey 12.3
Previously using 2018 MacBook Pro with Big Sur

Having a playback issue in ProTools:
Audio dropouts every 15 seconds for <1 second

Only seems to affect ProTools 2022.5.0
Browser audio playback unaffected
App Playback (Quicktime, Apple Music) unaffected
Garage Band unaffected

In PT:
Input Monitoring - affected
Playback - affected
Bounce files - affected

However, the actual Recording of the audio is NOT affected. The wav pattern appears uninterrupted, and when the dropout occurs, immediately replaying the section affected I'm hearing what was missed until the next dropout 15 seconds later.

Issue is not remedied by Reboot of either ProTools or System.

Additional Setup Info:
Focusrite Clarett 2Pre USB
Focusrite Control 3.11.0.1983
Firmware 1246

Everything plays fine when I switch back to the MacBook Pro setup. It's only on the Mini.

Any guesses?
Thank you!
