Problem with bluetooth audio output

Archive - Mycroft Project Picroft

Hi I have a problem outputting audio to my JBL GO bluetooth speaker. I managed to pair and connect to it but there is no sound.

Here’s documentation:

Picroft Outputting audio

Problems starts at “Next, we connect the audio.” section of “How to output audio through Bluetooth”

I installed everything that was needed

At 4 it states “edit” but there was no such file so I created new one and added that line.
At 5. there is no info where to add that lines… How to do this?

When I try to run pulseaudio it shows error:

E: [pulseaudio] module.c: Failed to load module “module-native-protocol-unix” (argument: “auth-anonymous=1 socket=/tmp/pulse-socket”): initialization failed.
E: [pulseaudio] main.c: Sink alsa_output.0.analog-stereo does not exist.
E: [pulseaudio] main.c: Module load failed.
E: [pulseaudio] main.c: Failed to initialize daemon.

Are you able to show the output of
sudo pactl list modules

I too have the same problem
and in the log it shows :

N: [pulseaudio] main.c: User-configured server at unix:/tmp/pulse-socket, refusi ng to start/autospawn.
Please help

Hi there @Sridevi_ram, welcome, it’s great to have you here.

In order to help troubleshoot, are you able to post the output of the following commands:

dmesg -i | grep blue

This command will tell us if there are any bluetooth-related error messages in dmesg - which is the system log.

sudo systemctl status blue*

This command tells us the status of all the bluetooth services on the device.

I believe using the unix: socket connection only works if you run pulseausio as system-wide deamon. (not sure though)

the word “User-configured” throws me off here. Are you sure you start PulseAudio as system-wide server under the root user (daemon-mode) and NOT as a normal user?

“start/autospawn” is also something that should not be done if ran as system-wide deamon…

I am also having some issues with pairing a bluetooth speaker to picroft.
i followed the same steps, however my issue begins at where it says

  • " Run pacmd list-sinks and note the Bluetooth sink name"

i dont see any bluetooth sink name? this is the output i get :

1 sink(s) available.

Hi there @sander we recently pulled in pulseaudio into Picroft, and we’re finding that it helps a lot with audio issues of all kinds, including Bluetooth. If you reboot Picroft it should pull in the most recent update.

It’s also worth trying alsamixer to see if you can select your device.
