Hi, @leka0024. Thank you for the info. Unfortunately, it looks like this is another issue. This script only changes the profile from HSP/HFP to A2DP once the headphones are successfully connected. I am sorry, it looks like some sort of incompatibility issue.

Does someone has the problem that the Headset Mode is working but on A2DP no sound can be heard? It was workings since i upgraded to 20.xx but since one week or so i have problems again. Removing and Repairing does sometimes fix the issue.

WH-1000XM3, newest firmware.

i am unable to as well on Linux Mint 20.1

This may or may not resolve your issue. I've found that on first connect it will not work with the headphones. I've had the Sony WH-1000xm3 and xm4's. My current simple fix is to connect the headphones, disconnect them and reconnect. Then click on the speaker icon and choose the applications tab and select the sound output to be the headphones. This is not a great work around, but it's the best that I've been able to come up with.

I've tested this on Ubuntu, mint and Mx Linux.

Does this work with Pipewire ?

thank you so much !
worked for me on Linux Mint 20.2 Cinnamon and Sony WH-1000XM3 headset .
happy new year !

I'm glad it is still useful :).

Thank you very much for this - worked perfectly out of the box with my Bose QCII Headset on Ubuntu 22.04.

Thanks, worked for me!

Thank you @egelev for the script. I changed it to make it wotk with PipeWire. You can see it here: https://gist.github.com/tbulligan/b92e85a6e89e218d711a97cfa38f855e
