No sound using A2DP sink with bluetooth

For whatever reason I cannot get my bluetooth audio to work. I have tried with my sony wf-1000xm3 and with a bluetooth speaker. The speaker will usually connect and maybe output audio for a split second but then no sound. The headphones hardly ever output sound but when they do it is because they are in handsfree mode with pretty bad audio quality. Most of the time it won't even do this and there is just no sound or even confirmation that it has connected. I tried going back to pulseaudio with

Code: Select all

systemctl --user unmask pulseaudio
systemctl --user --now enable pulseaudio.service pulseaudio.socket

but it does not help. I am also using easyeffects if that is relevant.

Please let me know if there is any more info that is relevant that I can provide. Thanks for the help!

Had a look and have pavucontrol installed. When the devices make no sound they don't even show in pavucontrol. If i try to change the audio profile in blueman I get "Failed to change profile to ..." and the options are all a2dp anyway.

Sometimes I get a notification about authorising a connection to a handsfree device but I don't know what I can do about this request and I want it in a2dp mode anyway.

I don't know why, but I can't bump this topic even though the last time I tried was probably over a week ago. Still haven't found a solution . This has been bugging me for months! I think it may be common for Lenovo thinkpads (I have a T14s Gen 3) but I have not come across a working solution yet.

I tried live booting LM 21.1 and 21.2 from a USB to see if I could get it to work there but no luck so it seems it isn't related to any additional software that I have installed.

Upgraded to 21.3 and 6.5.0-15-generic kernel. Still not working. Bluetooth sound registers as connected on the laptop but not on the bluetooth device. Don't really know what else I can try. Seems I can't bump the thread anymore which is weird.

I may have found a solution. For context, I am using a JLab Bluetooth headset which connects to both my primary personal PC (Linux Mint 21.3) and a laptop (Windows 10). While it does not like switching between two devices, including losing audio on the Mint PC when taking calls/audio on the Windows laptop, I encountered a new issue yesterday.

The Mint Bluetooth panel showed my headset connected, however I had no audio output on the A2DP profile, only on the HFP headset profile.

For additional context, here is my output from inxi -E

Code: Select all

Bluetooth:
  Device-1: Intel Bluetooth wireless interface type: USB driver: btusb
  Report: hciconfig ID: hci0 state: up address: 38:68:93:29:28:44 bt-v: 2.1

Having seen this thread and searched the web, the solution I found was on this Debian Wiki page

First thing I did:
1. Navigated to /var/lib/gdm3/.config/pulse/ in terminal
2. As I did not have the client.conf file, I used sudo touch to create it
3. Within terminal, used sudo nano to open the command-line text editor
4. Copy+pasted

Code: Select all

autospawn = no
daemon-binary = /bin/true

within the nano editor
5. Exited nano saving the changes.

Second thing I did:
1. Navigated to /etc/pulse/
2. Opened default.pa in nano with this command: sudo nano default.pa
3. At the bottom, I used ### to add a comment of what step I was referencing and it was on the Debian Wiki
4. Below that comment, I copy+pasted load-module module-switch-on-connect
5. Exited nano saving changes.

Once both of these were done, I rebooted my computer. It took a second longer to connect to my headset, however it did ultimately connect using the A2DP Sink for High Fidelity audio.

I don't have gdm3. I think LM 21.3 Cinnamon uses lightdm instead? For some reason I get a permissions error when trying to cd into it at /var/lib/lightdm . It says the owner is lightdm when I checked with ls -l. Not sure if I should change these permissions.

Mine already had a section

Code: Select all

.ifexists module-switch-on-connect.so
load-module module-switch-on-connect
.endif

which I assume is what it is referring to. Tried removing the if guards and rebooting but no luck it seems. Thanks for the suggestions anyway!

All good to hear tsoli, in fact I think a recent update to the Linux kernel itself fixed an autoconnect error. I had to revert the changes I did once I installed that update.
