Not sure if this counts as a bug, or feature request? But it seems no matter the platform, Kodi outputs PCM based mono tracks as stereo, bypassing the center channel if you have one. However, if you're using passthrough with a mono DTS/Dolby track, the center track works just fine (since it's your receiver doing the channel mapping). As someone with a very nice center channel, I'd very much like to use it. After speaking to a LibreELEC dev, it seems fixing this on a per-platform level is semi-possible, but not ideal, as each setup/config could be different, so it wouldn't be a deployable fix
Is it possoble to get a Kodi-side feature/option to output/transcode 1.0/mono tracks as multi-channel PCM, with everything but the center channels muted? Eg 1.0 -> 3.0 (or 5.1), with the FL/FR (or FL/FR/LFE/SL/SR) channels inaudible? Your receiver might light up a couple extra lights indicating more channels, but at least the PCM output would finally be an match to its DTS-HD or TrueHD source
Or could there possibly be other solves? Would it be possible to directly transcode to mono DTS-HD or TrueHD? It would obviously be turned back into PCM again, but not until the receiver end, so it would also be appearing as a proper mono track to the receiver (or anything else in the chain)
