Incorrect Channel Mapping with Multichannel OGG Playback

Installed LibreELEC on a friends Raspberry Pi 4 and ran into an issue. I copied a lot of multichannel 5.1 movies & music with audio formats AAC, OGG & FLAC that all play properly on my Pi 3 with OSMC, but on my friends Pi4 with LibreELEC the channel mapping with any audio formats that the receiver converts to PCM are completely screwed up. If a log file is needed I'll get one but in the meantime is there quick fix for this?

Thanks!

So I've been at my friends who I sent up the R Pi for messing with the settings and just can't seem to get these multichannel music files playing back correctly.

This is a pretty old feature as I've been playing back multichannel music in multiple formats for years now. Like you said Noggin, there are PCM audio channel mapping issues as AAC, FLAC & ogg (Vorbis) files are recognized as PCM on receivers.

Can you guys help out with a fix for this please? Thank you,.
