Transcode for multichannel audio (EAC3, TrueHD etc) are transcoded to 2 ch Opus instead of 5.1 AC3 when using optical. In settings pass through is set to optical. AC3 set as supported, DTS set to not supported. AC3 movies AC3 is passed through. All other audio (multichannel) are converted to opu…

Can confirm. Same issue for me, running Plex App on an Sony Android TV. 28030 and older play E-AC3 just fine, on later builds it gets transcoded to Opus 2ch due to E-AC3 not being supported.

Again, same issue here. Hope it resolved quickly!

8.24.0.28372 is still exhibiting the same issue: PlexServer.log (66.2 KB) androidTV.log (53.5 KB)

This change in transcoding has now hit the stable Android release. From my conversation with one Plex employee, it’s unlikely that this will be fixed. I was told that they aren’t many people using passthrough and that Plex needs to do what’s best for the greatest number of users (so not us) …

Thank you, I’m glad to hear it. As I said early, I asked how to get AC3 transcoding to work over optical passthrough following this latest update. I got a lot of talk about how Opus is better, and why would I even want to use AC3, and Opus can be sent to my receiver instead of AC3. I was never on…

Were not retiring optical passthrough, this was a regression that was overlooked due to the inclusion of Opus and other codecs as transcode targets - which as I mentioned above does improve things except when using optical. Will be fixed in the new beta, should be available later today.

Thank you, just adding my voice to this, I also use optical.

Great new. Guessed it had something to do with the implementation of Opus. Will test the new beta with as soon as it’s out! Thanks!
