Some audio doesn't play on Jellyfin on bazzite

Hey all, I'm hoping this is simple one of you have seen. I have Jellyfin media player installed on bazzite, I use it through gaming mode. Most of the time, but some audio tracks are silent and won't play unless I force transcoding.

They are usually DTS or DTS:MA. Do I need to install drivers somehow? Or flip a setting? I'm fine with transcoding audio, but I want to avoid transcoding video.

I am plugged into an Onkyo receiver via HDMI, so it should be able to play most of those.

Thanks!
