@kohelet@daevien@zlendy I don't have any experience with navidrome, but I think your hypothesis is solid. With #jellyfin, I have a mix of +-320kb/s mp3, flac, and opus and it all plays seemlessly next to each other in #Symphonium, both in my phone and through android auto. It's not clear to me what side, symphonium or jellyfin, is doing the heavy lifting of making it play out my car speakers, but it just works so I don't have to care too much!
