Multichannel FLAC in 5.9-026 not working on shield tv

Hi I still can’t get Pink Floyd Dark Side of the Moon multichannel FLAC files to work in the 5.9 beta, though 5.8 claims to have fixed this. When I play the song it simply skips to the next song. I can supply a link to one song if anyone needs it for testing, or please let me know what else you’d like from me. Thanks!

BTW my original posting about this is here: https://forums.plex.tv/discussion/267493/multichannel-flac-music-on-shield-tv-unplayable

It definitely works in 5.8. I’ll check 5.9.

You are using HDMI right? HDMI TO AVR THEN HDMI TO TV?
