Hi ​@brokenboxes 

“Long story short, Sonos Home Theatre devices do not support the AAC codec via HDMI/Optical - only when streaming or playing from Music Library.”

All my movies have AAC audio and play fine; it’s just the mono ones that wouldn’t play. Also, AAC is supported by Sonos according to the documentation.

Please see our Supported home theater audio formats help page. AAC is not listed.

“I do now wonder if there was a way to do it with your older Apple TV.”

I didn’t have an older Apple TV, was just using the plex app on the Samsung TV. Either way, it now works, I’m not exactly sure on what was going on technically that prevented it.

Understood! In that case, I think it was probably just that the Samsung Plex app was a bit limited or old.

Yes, the important point is that you can now watch your older movies - enjoy!
