Pulseaudio:snapserver doesn't show in LibreELEC audio output options

[stonster]

Hi all, just trying to get a little help with snapcast snapserver side on a pi running LibreELEC...

Running Kodi 18.9.0
and libreELEC 9.2.7
on a raspberry pi3.

I can install snapserver and snapclient as per this guide

BUT when I go to try to find PULSE: Snapserver in Settings/System/Audio/Audio output device, it's not listed as one of the options. Weird thing is though, I've had it working once and available in the last 24 hours. It appeared, I selected it, then the system worked beautifully and my pi downstairs picked it up straightaway. After rebooting PULSE: Snapserver disappeared. Only PULSE:bluetooth is left, which doesn't appear to work.

Any thoughts on getting PULSE: Snapserver in Settings/System/Audio/Audio output device? I tried disabling and reenabling bluetooth, but no joy.

From what I can search, I don't seem to be the only one who's had this issue, but I can't find it resolved anywhere?
