Cannot listen on a Bluetooth socket
My system is Fedora 34 (prerelease), PipeWire version is:
$ pipewire --version
pipewire
Compiled with libpipewire 0.3.23
Linked with libpipewire 0.3.23I'm getting the following error:
pipewire-media-session[2561]: native: listen(): Address already in usefrom this code: https://gitlab.freedesktop.org/pipewire/pipewire/-/blob/662fd8a1f9d769c5a407b6dbe054bdcc53caa481/spa/plugins/bluez5/backend-native.c#L910-936
I admit I don't really know anything about Bluetooth, but that sounds as if something else on my system also listens on the same BDADDR_ANY address, and that interferes with what PipeWire is trying to do.
I have bluetoothd running, but it doesn't seem to have any SCO sockets open:
