Instructions to replace PulseAudio with PipeWire on debian 11.

sudo apt install -t backports pipewire pipewire-alsa pipewire-audio-client-libraries 

Populate config files in /etc/pipewire/media-session.d:

# Set up basic config files
sudo touch /etc/pipewire/media-session.d/with-pulseaudio
sudo cp /usr/share/doc/pipewire/examples/systemd/user/pipewire-pulse.* /etc/systemd/user/

Put the content below in the file at /etc/pipewire/media-session.d/bluez-monitor.conf to enable extra codecs:

properties = {
    bluez5.msbc-support = true
    bluez5.enable-msbc = true
    bluez5.sbc-xq-support = true
    bluez5.codecs = [sbc sbc_xq]
}

Reload daemon file for systemd and start service:

systemctl --user daemon-reload

# disable pulse audio
systemctl --user --now disable pulseaudio.service pulseaudio.socket

# enable pipewire
systemctl --user --now enable pipewire pipewire-pulse

# mask pulseaudio
systemctl --user mask pulseaudio

now reboot and try :)
