I've been looking around for couple of days to find out why my bluetooth headset is not working. No luck to find the correct answer.
I'm running Ubuntu 22.04 with all the latest updates on brand new Lenovo T14 Gen 4 AMD laptop with Qualcomm Atheros QCNFA765 chipset. So far I do not have problems to connect any other bluetooth device such as mouse or my mobile phone.
Starting from beginning.After fresh install, when I connect my headphones, I couldn't hear any sound out of it even when they are selected as an sound sink device. After some time, headphones disconnects from the system. Doesn't matter which profile I've been using (A2DC or HSF).
Sometimes when I try to connect my headphones manually, I got an error tht connection failed. Nor info from bluetoothctl output.
Output of syslog:

No luck to find a solution.
As suggested on one of the forum, I've upgraded my system to pipewire set-up. Problem still exist.
Output of wpctl status command:

At the moment I do not have a chance to verify my computer hardware with Windows based OS. I've ordered an external USB bluetooth dongle which will arrive after the weekend. Let see.
Thank you in advance.
