Hi! Finally installed a2dp-app-osmc. I had to make some changes in order to make it play nicely with my retrosmc/emulationstation/retropie installation besides it.
I changed the following:

in file: /etc/pulse/client.conf (makes pactl work):

default-server = /var/run/pulse/native

In file /etc/pulse/daemon.conf (fixes audio / emulationstation buffer underruns; source: https://bbs.archlinux.org/viewtopic.php?id=185736 ):

default-fragments = 5
default-fragment-size-msec = 2

in file /etc/pulse/system.pa':

load-module module-cli-protocol-unix

(This enables the use of pacmd command. Example:

osmc@osmc:~$ sudo su
root@osmc:/home/osmc# export PULSE_RUNTIME_PATH=/var/run/pulse
root@osmc:/home/osmc# pacmd
Welcome to PulseAudio 10.0! Use "help" for usage information.
>>> ^C

However, you're advised against doing this due to security reasons. Just like you're advised against running pulseaudio systemwide.. but this is not really a problem in single-user htpc scenarios)

I also changed the following settings in /etc/pulse/daemon.conf:

high-priority = yes
nice-level = -11
exit-idle-time = -1
flat-volumes = no
default-sample-rate = 48000
resample-method = speex-float-5

default-sample-rate to 48000 as that is default of emulationstation, and changd the resample-method.

Now I can play audio via bluetooth on osmc and play star wars rogue squadron on my rpi3b+ at the same time; yay!

We found some regressions from running PulseAudio in system-wide mode.
You should be able to use the ALSA sink (bcm2835-alsa) on Pi and the Pulse sink simultaneously for dual audio output.
