I'm running a new installation of the server and LibreELEC (this worked fine on my previous installs, but I decided to fix what ain't broke).
I'm casting over the LAN from the server on Debian to LibreElec on a Rraspberry Pi.
The problem I'm encountering now is that LibreElec will hang and show a spinner for anywhere from 15 seconds to several minutes when advancing to the next track of an album or music playlist. It only breaks when I'm casting, not when I'm playing locally through the Player. It only breaks for FLAC files, not Mp3s, so transcoding seems to have something to do with it.
I've disabled playback of transcoded audio in the user's settings and restarted the server, but it didn't change anything.

Where should I be looking to figure this out?
