M1 iMac audio "stutter"
In the past couple of weeks I've been experiencing an audio issue using Apple's TV app on my 24" M1 iMac - there's a noise "stutter" that begins at inconsistent times after playing for awhile. This is with internal speakers, does not occur with Bose QC35-II bluetooth headphones. It is NOT an internet connectivity, speed or buffering issue, and will occur with no other programs running in the background. Not corrected by quit/restart of the program, may be corrected by full shutdown/restart. Running Monterey 12.1; I believe it's only occurred after the last update.
It's most noticeable with soundtrack music, frequency a regular something like 6 Hz, hard to tell if it's momentary cut-out (which it seems) or insertion of noise.
