I have just moved from OSMC to LibreELEC to take advantage of my Raspberry Pi 4 and was very excited to see that there is an easy way to cast Kodi output through Snapcast.
However, after installing the addon, I do not see the PULSE: Snapserver device in the audio output selection box.
I did a bit more digging and found that Pulseaudio could not start because of Bluetooth being disabled.
After enabling it, I got pulseaudio starting.
The device name in Kodi was still PULSE: Default Bluetooth, but selecting this made snapcast work just fine
