Marshall Kilburn 2 Bluetooth speaker connects but no audio output on Fedora 43

Hello everyone,

I’m experiencing a strange issue with my Marshall Kilburn 2 Bluetooth speaker on Fedora 43. The speaker connects successfully and the system shows audio visualization in settings (indicating audio is being sent), but there’s no actual sound output from the speaker.

What I’ve verified:

  1. The speaker itself works fine - tested successfully with Windows 11 and Android 16
  2. The issue is reproducible across multiple machines - tested on 3 different computers (2 laptops and 1 desktop), all running Fedora 43, same problem on all of them
  3. Other Bluetooth audio devices work fine on Fedora 43 - Sony headphones connect and play audio without issues on the same PC
  4. All drivers and services are properly installed - bluetooth services are running, checks pass successfully

This appears to be a very specific compatibility issue between Fedora 43 and the Marshall Kilburn 2 speaker. I haven’t found similar reports on forums, which makes it even more puzzling.

The system recognizes the device (pactl shows both ALSA and module-bluez5-device.c cards), audio routing appears to work (visualizations respond), but no sound comes out of the speaker.

Has anyone encountered a similar issue with Marshall speakers or this specific model on Fedora 43? Any suggestions for troubleshooting or configuration tweaks would be greatly appreciated.

System info:

  • OS: Fedora 43
  • Audio system: PipeWire/PulseAudio
  • Device: Marshall Kilburn 2 Bluetooth speaker
  • Bluetooth services: Active and running

Thanks in advance for any help!
