Bluetooth does not work with Pipewire (solved-ish)

My bluetooth headphones work with pulseaudio-bluetooth and bluez, but if I install pipewire, it fails, although bluetoothctl indicates that they have successfully connected.  Bluetooth fails with Pipewire even when I am not using pipewire-pulse.

lsusb:

Bus 001 Device 003: ID 8087:0aa7 Intel Corp. Wireless-AC 3168 Bluetooth

rfkill --output-all:

#
# You can optionally start the pulseaudio-server here as well
# but it better to start it as a systemd service.
# It can be interesting to start another daemon here that listens
# on another address with the -a option (eg. -a tcp:4713)
#
#exec /usr/bin/pipewire-pulse

EDIT:
Apparently the script mentioned here solves my problem.  So, even though everything is working for pipewire and bluetooth, apparently it is not switching over to the bluetooth sink and/or not directing input to the bluetooth sink.  I suppose for now, I will use the script.  For anyone else reading this, don't forget to edit the udev rule to reflect the bluetooth device you are using.

Re: Bluetooth does not work with Pipewire (solved-ish)

What about out of sync BT audio/video with PW? Anyone have that? Contrary to PA you can't set an offset latency
