I’m trying to pair audio devices (bt earphones, bt speaker) with my Thinkpad P14s gen 2 (NixOS 23.11). Every attempt fails with:
[bluetooth]# pair C0:(...):4F
Attempting to pair with C0:(...):4F
[CHG] Device C0:(...):4F Connected: yes
Failed to pair: org.bluez.Error.AuthenticationFailed
[CHG] Device C0:(...):4F Connected: no
For context:
I remember it used to work in the past. I am not sure at which moment it stopped.
Also, other devices (like mouse) have no trouble pairing. The sound itself also works.
Here is what I already tried:
[on other OS]
- pairing with another PC (Ubuntu) - works fine,
- pairing on same PC (Ubuntu, Windows 11) - works fine;
[on NixOS]
- pairing via external bluetooth USB dongle - works fine,
- pairing via builtin bluetooth adapter - does not work,
- pairing using bluetoothctl and graphical blueman-manager - neither does work,
- restart services - does not work,
- reset all known bluetooth devices - does not work,
- reinstall NixOS - does not work,
- use default NixOS graphical (with pulseaudio, pipewire) and minimal configuration (with bluetooth and pulseaudio) - neither does work;
Please help
