Edit Reason: ETA - changed "bitrate"
)
[JBL Flip 2 Bluetooth speaker used in all "MPD audio output -> Bluetooth" testing. All Pi's under test are connected to LAN via onboard WiFi.]
I do have a Zero 2 W and an audio dropout roughly every 0.5 sec seems to occur only with it running moOde 8.0.2 (32-bit) or 8.1.2 (32-bit and 64-bit). It does not occur with the Zero 2 W running moOde 7.6.1 (32-bit). I'm not seeing any suggestive messages in the logs.
However, Bluetooth audio output seems fine running moOde 8.1.2 on any of an old Zero W (32-bit moOde), several Pi3A+ (32-bit and 64-bit moOde), a Pi3B+ (64-bit moOde). I believe it was ok on an RPi4B too but it's not available ATM to check.
Very curious. ISTR long ago getting a similar but not necessarily the same repetitive interruption to output when I was first using my Creative Tech USB-BT adapter. IIRC the problem then was due to mismatched bitrate sampling frequency but the problem disappeared at some point in the evolution of moOde and I haven't thought about it in years.
I suppose a recent change to kernel/drivers could be implicated but it's not obvious why it would affect only the Zero 2 W. A quick search didn't turn up an useful hits on the Raspberry Pi Forum.
