[PROBLEM] Can't turn off Bluetooth!

[Sehnsucht]

Edit: Eventually solved this!

---

I've got a Pi Zero W system up and running perfectly with wired headphones, and then I decided to try and get my bluetooth headphones working.  That was find too, but now I find I cannot switch back to wired headphones.   I'm using the Apple USB -> 3.5mm dongle.  When I try and play music now, my mpg log file says:

ALSA lib ../../../src/asound/bluealsa-pcm.c:897_snd_pcm_bluealsa_open) Couldn't get BlueALSA PCM: The name org.bluealsa was not provided by any .service files
Jul 11 12:14 : exception: Failed to open "ALSA Default" (alsa); Failed to open ALSA device "_audioout": No such device
Jul 11 12:14 : exception: Failed to open "ALSA Default" (alsa); Failed to open ALSA device "_audioout": No such device
Jul 11 12:14 : player: problems opening audio device while playing "SDCARD/music/Electronic/01 - Sexual Harrassment In The Workplace.flac"

For each track.   I get a popup from the web interface too:

MPD error
Failed to open "ALSA Default" (alsa); Failed to open ALSA device "_audioout": No such device

When I got into the mpd page in the web interface it says:

MPD settings cannot be changed when Audio output is set to Bluetooth.

Although if that means the Output Device under Audio Output, bluetooth is not an option there (just the USB one and  HDMI).  I don't see much in the way of Bluetooth options except for on the Audio Config page where Bluetooth, pairing agent etc is all turned off.   I also tried turning off "Integrated BT adapter" on the System Config page. 


Here's the moodeutl -l output:

This looks wrong:
20210711 121347 worker: MPD output 1 ALSA Default (off)
20210711 121347 worker: MPD output 2 ALSA Bluetooth (on)
20210711 121347 worker: MPD output 3 HTTP Server (off)

I've used M.A.L.P. (Android mpd client) on my other Moode (Pi 4) system with no problem; when using that on this one I've selected Alsa Default as the output.  I don't see bluetooth enabled anywhere.  Is there a config file somewhere that's got into an odd state?

Edit: When I try and set mpd output to "local" in the bluez config page it hangs the web interface.

Edit: Upon reboot I could then set the output to the USB.
