Hi there,
After one of the recent upgrades, the Bluetooth audio configuration for my Bluetooth receiver (MR280) stopped working.
I can still select the audio profile after connecting via Bluetooth, but in KDE’s Sound settings the device appears under “Inactive Cards” when I choose “A2DP Source & HSP/HFP AG.”
I’m able to choose one of the High Fidelity Duplex audio profiles, but there’s no sound. I haven’t changed my configuration, and the device had been working consistently until now.
Could this be caused by the recent kernel upgrade, or did something change in the PipeWire/WirePlumber configuration?
Some system infos:
