I listen to music via Bluetooth on a BoseQC45 headphones on a M1 Max (64GB Ram) without any memory pressure, and this glitch happens very often (while typing this text, the glitch happened at least 3 times - it sounds like a scratch sound you would get on the old vinyl records).
For me I noticed the glitch or pop / crackle sound occurs when a A2DP packet flushed occurs.
At first I thought it was RF interference, but I am doubting this more and more. I am considering getting a bluetooth dongle for the M1, but have not gotten round to
do that just yet.
Has apple responded to this problem in this thread yet?
Here is a log extract of when the sound glitch occurs:
