With passthrough and 2.0 my outputs are 2.0. To get 5.0 I need to set-up to 5.0.
Is it a bug or not?

Not sure if that information is still accurate - I keep adding it to the release notes until I'm told it's no longer required... One for popcornmix to answer/confirm, as with all the changes and fixes for audio in recent firmware the situation may have changed. I'm not connected to an amp so have no way to test audio settings beyond basic stereo.

I use passthrough, have set audio to 2.0 in accordance with the instructions and DO get 5.1 with (5.1) AC3 audio. Using recent builds.

Is there a way you could share a copy of your config (if you agree) to test in my RPi?
Let me know.
Thanks
