I run Kodi on a 2019 Nvidia shield "tube" model. My media and previously jellyfin is on a NAS that serves the content over nfs to the shield. Shield--Receiver--TV. Look into the maven Kodi build if you have something similar. My sync issues went away using when I stopped using jellyfin and also maybe from removing path substitution when I redid it from scratch. I believe I have fixed output with passthrough in Kodi and upmixed turned off on the shield.
