Hi all,
Having an issue pairing a Bluetooth headset where my PC says pairing and connection was successful but no recognition of pairing on the headset (normally it says “connected” when successful).
The headset also does not appear as a sound device when the PC says it is connected. The device I am trying to connect is called " EarFun Wave Pro". Other Bluetooth headphones, such as Samsung devices, can pair and connect without any issue.
I’ve tried:
- Switching between PulseAudio and PipeWire
- Using Blueman
- Manually pairing through bluetoothctl
- Checking for pairing errors in btmon
Linux version:
Linux Cider 6.6.72 #1-NixOS SMP PREEMPT_DYNAMIC Fri Jan 17 12:36:27 UTC 2025 x86_64 GNU/Linux
Nixos version:
