Thanks for providing the log file. I don't notice anything different between the 2 runs, so it's not something related to a configuration. Try removing pulseaudio completely then reboot the system, this might get rid of any PA interference.

The finally solution for me was manage the relationship 1:1, one speaker with one dongle (USB). For spread the sound on all speaker i used an virtual audio card with "paprefs". Maybe we'll see this skills on new Bluetooth versions.

Sorry for the lengthy delay in replying... IRL got in the way :-) OK so it's definitely only the navigation sounds missing. I've tried several themes and none seem to have sound. I'm guessing they must not be supported in Ubuntu as i don't seem to have them in the Sound Settings menu item. Oh well :-)

Ah, should have read the rules properly sorry

Only audio issues I noted were when I closed out of Kodi, the menu audio was off by a second or so.

Has this still worked overtime? Or have you run into issues with updating?
