I do have exactly same problem. Few weeks ago AC3 audio worked fine, one week ago it stopped. Android TV version 2.1.23g, device is Strong Leap S1 (kind of older device). Looks like this might be widespread bug.

EAC3 is very different from AC3 codec.  Apparently some versions of EAC3 were supported in Andorid and it looks like some are not.  Also Android support may have removed many versions of EAC3 around the end of 2024.

I am sure if you dig deeper you can get more exact information or someone in the forum already knows exactly what happened.  Here is a page that posts steps to convert a file from EAC3 back to another codec.  I am sure that will probably fix these issues, but it seems this is not really the question.  Why did the media playback before and now it doesn't?  Is it the same exact media copy that failed or are you talking about other AC3 audio, which is not the same as EAC3?  

The posts above show screenshots of EAC3 and text questions about AC3.  Which is it?  They are not the same.

I just found a solution that works for me. I tried older versions of Emby, but it did not help. However, playig with settings in Emby, if I go to to playback and select stereo audio output instead of auto, the AC3 sound is back.

I do not understand what happened, I did not make any changes and it for whatever reason stopped working in auto audio output setting.

Jan,

Interesting. Grabbing a log, when it didn't work, would have helped find the problem.

The only Emby info page I found in the guide is: https://emby.media/support/articles/LG-Why-not-Atmos.html?q=EAC3
