Couldn't get BlueALSA PCM list: Rejected send message

[hymie0]

Hello.

I'm brand new to the world of Bluetooth, and I hope you can point what I (probably) did wrong.

I have my Jabra headset paired to my computer.

I set up my /etc/asound.conf

pcm.btheadset {
   type plug
   slave {
       pcm {
           type bluealsa
           device 30:50:75:43:F4:AE
           profile "a2dp"
       }   
   }   
   hint {
       show on
       description "BT Headset"
   }   
}

Then I run bluealsa ...

% sudo src/bluealsa

But none of the tools are succeeding.

% amixer -D bluealsa

Can you give me a push?

OK, I think I found my first mistake. I had to be running bluealso before I paired the headphones. Now I run bluealsa and I have this:

but I'm still having no luck with

% amixer -D bluealsa

Rejected send message, 1 matched rules

This is a message from D-Bus daemon which have its own ACL system (other than UNIX's DAC). You need properly configured /etc/dbus-1/system.d/bluealsa.conf file (assuming that on your distro this config file is in that location). By default only root and user in the audio group are allowed to connect with bluealsa service.

[hymie0]

You're right ... things work fine for root so it must be a permission error.

However, my user is in the audio group, so I'm not sure what the next step is.

% groups
hymie root disk lp floppy dialout audio video cdrom netdev scanner vboxusers

=====

I (think I) figured it out. Even though my groups listing includes "audio" , I'm not listed in /etc/group in the "audio" group. Once I did that, things are working.

Thank you for the help!
