Bluetooth Headphones

Only need to run PA with xbian user privies:

Terminal

xbian@avr ~ $ ps -o user,cmd -C kodi.bin
USER CMD
xbian /usr/local/lib/kodi/kodi.bin --standalone -fs --lircdev /run/lirc/lircd

I believe in the past, I added something like below to /etc/rc.local to have PA started before the xbian user logs in:

Code:

sudo -u xbian '/usr/bin/pulseaudio --start'

Could change it into more specific one from @Nachteule:

Code:

sudo -u xbian '/usr/bin/pulseaudio --start --system --log-target=syslog'

And add the /usr/bin/pulseaudio command to the sudoers list of commands in below file:

Terminal

xbian@avr ~ $ sudo cat /etc/sudoers.d/xbian
xbian ALL=(ALL) NOPASSWD: /sbin/initctl, /usr/local/sbin/xbian-config, /sbin/halt, /sbin/reboot, /usr/bin/splash, \
/usr/bin/renice, /sbin/start, /sbin/stop, /sbin/status, /bin/fuser, /sbin/restart, /usr/bin/pkill, /usr/sbin/btrfs-auto-snapshot, \
/bin/mount, /bin/umount, /bin/kill, /usr/local/sbin/splash-daemon, /bin/rm -fr /run/splash/splash.pid, /bin/mkdir -p -m 777 /run/splash, \
/usr/bin/setterm, /usr/bin/pulseaudio

What I miss in the instructions thread is selecting BT profile.
It could be that your headset defaults to low quality output profile with a mic input when connected at first.
You want to have the a2dp profile/sink (if headset supports) to get best quality.
Below ones might be useful once headset connected:

Code:

pacmd list-cards

pactl list cards

pactl list cards short

pactl list sinks

pactl list sinks short

For my Bose BT speaker, I had to do below to get the a2dp profile/sink activated:

Code:

pacmd set-card-profile bluez_card.00_0C_8A_XX_XX_XX a2dp_sink

pacmd set-default-sink bluez_sink.00_0C_8A_XX_XX_XX.a2dp_sink

Test with below:

Code:

pacat --list-file-formats

pacat < /dev/urandom

pacat --file-format=wav <A_RANDOM_WAV_FILE>

EDIT: added sudoers.
