Also when it connects you can hardly move the speaker a couple of ft away (from what I remember that is) untill it fully drops connection. ...
We seem to be in agreement about the driver/chipset. They are both different for the Zero 2 W versus any of the other Pi models with onboard WiFi/BT hardware. Trouble is, that's the most opaque part of the system. The chipset and firmware (low-level driver) are basically proprietary to Broadcom (well, Synaptics now, actually) and the Raspberry Pi Foundation's documentation about both is essentially nonexistent. It's tiresome trying to characterize a system by wading through the journalctl output.
That this audio "motorboat" effect seems quantitatively different for moOde 7.6.1 and moOde 8.1.2 highlights for me the importance of the driver/firmware but I'm not really interested in comparing the undocumented /lib/firmware/brcm files between the relevant versions of Raspberry Pi OS. Several attempts exercising my Google-fu failed to turn up useful leads. Mostly it finds users with WiFi problems flailing like blindfolded kids swinging for a fiesta piñata. No candy yet.
As for your diminished BT range with the Pi Zero 2 W, that's unexpected. I'm sitting here listening to my JBL BT speaker putt-putting at the far end of my house from my Pi Zero 2 W---some 30 feet and several walls apart and no problem maintaining the connection.
My approach to the Raspberry Pi forum would be to start with a clean install of the current headless Raspberry Pi OS; install just enough to get bluez-alsa running; and test for the same effect using just aplayer. Assuming the effect is still there, one has a basis for discussion with the wizards of the RPF unencumbered by moOde application-layer stuff. (If the effect isn't still there, of course, there is a discussion to be had here!)
Trouble is, my partner is in the midst of her (mild) Covid-19 bout and I'm kind of preoccupied. Maybe I'll get back to the Zero 2 W soon; maybe not.
