[SOLVED]Bluetooth / PulseAudio Issue

Ive spent the last 2 days trying to figure this one out
-
I am trying to set up my new arch machine and only issue i have not been able  to fix is setting up my Bluetooth headphones. Im using bluez/ blueman/ pulseaudio - and read the wiki but im still a bit confused as im still pretty new to linux and this issuse is a bit complex !

I dont know where to start tbh because in the wiki it says for example -
Add your user to the lp group, then restart pulseaudio. See /etc/dbus-1/system.d/bluetooth.conf for reference.  ( but my machine does not even have a etc/dbus-1 file? )

other problems i have found:

pactl load-module module-bluetooth-discover
Failure: Module initialization failed

systemctl output -

Re: [SOLVED]Bluetooth / PulseAudio Issue

use pipewire instead of pulseaudio and check if the problem exits.

Re: [SOLVED]Bluetooth / PulseAudio Issue

Make sure you are up to date bluez 5.59 had a bug that's fixed in 5.60 and remove /var/lib/bluetooth and explicitly re-pair your headphone to be sure.

Why are you trying to start pulse in system mode? You'd use

systemctl --user status pulseaudio

as your user to check service status.

Re: [SOLVED]Bluetooth / PulseAudio Issue

i was getting ready to use pipewire but i wanted pulse fixed !

i was annoyed because when i did my first install which was pretty recent everything worked fine, then i decided to reinstall my system encrypted, messed with blackarch and then this problem kept showing up.. I think it was something to do with the order in which bluetooth and pulseaudio is set up. I have since got everything up and running on a clean install and i set up bluez blueman first and saved pulseaudio for last.
im sorry i dont have any more detailed info as im still a complete noob here.

Re: [SOLVED]Bluetooth / PulseAudio Issue

If you really want to use pipewire use pipewire. It replaces pulse for all practical purposes and comes with it's own set of improvements and issues and trying to fix pulse first will be useless if you need to do the same rain and dance on pipewire again.

bluez 5.60 got released on the day you made your post. If you were on an older mirror or hadn't updated yet when you formulated your post, there was a known issue with bluez that lead to errors accessing the A2DP profile. This isn't anything you messed up but a bug in bluez that affected both pulse and pipewire (... or rather every bluetooth device).

If the issue is fixed now, please mark the thread as [SOLVED] by editing the title in your first post.
