Hello @ferranmc,
In terms of software, what are you using for the bluetooth audio communication?
From your previous post, you mentioned that you had to disable bluealsa to get pulseaudio to work properly when executed by a non-root user.
Bluealsa should still be a viable alternative here, but you would need to use the module-alsa-sink and pass the device=bluetooth argument when loading this plugin.
Did you take this approach?
If not, what is your setup?
Best Regards,
Bruno
