Description of problem:

I usually disable the bluetooth service on my laptop since I don't use bluetooth. I recently upgraded from Fedora 33 to 34 and noticed my audio wasn't working anymore.

No sound output can be selected and playing any Youtube video on Firefox hangs.

Starting the bluetooth service again, and then restarting the pipewire and pipewire-pulse service at the user level resolve this.

Version-Release number of selected component (if applicable):
- Fedora 34 with all packages updated
- pipewire0.2-libs-0.2.7-5.fc34.x86_64
- pipewire-libs-0.3.26-4.fc34.x86_64
- pipewire-0.3.26-4.fc34.x86_64
- pipewire-alsa-0.3.26-4.fc34.x86_64
- pipewire-gstreamer-0.3.26-4.fc34.x86_64
- pipewire-jack-audio-connection-kit-0.3.26-4.fc34.x86_64
- pipewire-utils-0.3.26-4.fc34.x86_64
- pipewire-pulseaudio-0.3.26-4.fc34.x86_64

- Lenovo Thinkpad T490s

How reproducible: Always

Steps to Reproduce:
1. Disable bluetooth.service.
2. Restart pipewire.service
3. Watch audio output interface disappear

Actual results: Sound doesn't work anymore

Expected results: Sound works

Additional info:

pulseaudio worked for me with bluetooth service disabled. I'd like the same behaviour on pipewire.

As an aside, pipewire works beautifully with my bluetooth earbuds. Great job! :)

Can reproduce, but I think this has been fixed upstream: https://gitlab.freedesktop.org/pipewire/pipewire/-/issues/1114.

Comment 2 Matthias Runge 2021-05-03 16:05:21 UTC
This is a recent change, it worked for me with disconnected bluetooth in 0.3.25.
