Android TV client outputting multi-channel FLAC albums in stereo

[retrofan01]

Thanks for pointing me on the right track - I went to Android Settings -> Devices Preferences -> Display & Sound -> Advanced sound settings and set 'Dolby audio processing' to disabled. This seems to have solved the issue although I didn't realise the Jellyfin client didn't have gapless playback.

I've switched to Symfonium instead (still using Jellyfin as the backend music server) and gapless playback with 5.1 input signal seems to work correctly.
