[SOLVED] ADP2 audio problems with pulse and bluez

Good morning,

I have been using an arch configuration for a while, but I recently (well... this evening) switched from Gnome on Xorg to Wayland (since it now finally works with Nvidia cards!). Everything seems to be ok, but I am having some problems adapting a script I used to workaround a pulseaudio problem. Basically I am using bluetooth headphones, which did not work with the ADP2 module because of a bug cited here:

https://bbs.archlinux.org/viewtopic.php?id=194006

The workaround involves changing a line on

/etc/pulse/default.pa

And specifically commenting this module:

#load-module module-bluetooth-discover

And then going to edit this file:

/usr/bin/start-pulseaudio-x11

to start up the module after X has started:

if [ x”$SESSION_MANAGER” != x ] ; then
     /usr/bin/pactl load-module module-x11-xsmp “display=$DISPLAY session_manager=$SESSION_MANAGER” > /dev/null
fi


/usr/bin/pactl load-module module-bluetooth-discover

Now, here is my problem. Of course this script won't even load if I run Wayland. Where would the correct place be if I were to start up this module by a script and I am not using Xorg anymore?

Cause alas, the bug is still there and I won't be able to use stereo headphones unless I use this workaround (or I start the module manually after I get to the graphical interface every time.

Thank you in advance for your help!

Gian

Re: [SOLVED] ADP2 audio problems with pulse and bluez

Ok, I checked and the problem does not seem to be wayland since... even if I select Gnome at graphical login instead of Gnome on Xorg,Gnome Shell apparently crashes on startup (I thought the problem was solved in the 3.24 release and I will post a new thread about this. But now... why does not the script work anymore (it does work if I launch the module manually)?

Re: [SOLVED] ADP2 audio problems with pulse and bluez

Pulseaudio is usually started via systemd now, I doubt that this script is being executed. However module-bluethooth-discover should be loaded by default normally, what's in your /etc/pulse/default.pa ? I'm also not sure if maybe GDM poses a problem here since it uses its own config files. You might want to figure out where GDM's equivalent of the default.pa is located and add the module load there.

I find it strange that this would be in any way tied to X11, another thing you might try is drop a script with the pactl command in /etc/environment which should be executed even with wayland on login, I'm not sure if it starts up too early then.

Re: [SOLVED] ADP2 audio problems with pulse and bluez

Ok, I found and solved the problem (at least for now). The issue was that a pulse audio update overwrote the script where I put the module start up. I rewrote it as before. And indeed it does work (without loading the module after the session is up, the adp2 profile does not work (and I have only mono audio) or the device does not even connect. With the script, everything works (with the unconvenience I have to use a mono only HFP profile if I want to use the mic, which I almost never use anyway - this is  a bluez issue I seem to remember...).

In any case, since you asked, my default.pa is here:
