I’m a regular RPi OSMC user, since the model B, and I get confused sometimes on sound settings as I have four RPis with four different amplifiers, and they’re all a bit different with various formats. However, generally speaking, my RPis are setup with passthrough enabled for the sound, and via hdmi they’re setup for 2.0 speakers (the default setting), and they generally play AAC5.1 as 5.1.
Just plugged in a brand new Vero 4K+ and it seems the amp won’t see the AAC5.1 as anything other than stereo unless I do the opposite of what I’ve done for all the RPis and set 5.1 as the output in the audio section of system.
DTS and DD5.1 seemed to be pushed straight to the amp when it was set to 2.0 if that makes any difference.
Is this a thing? Or is there something fundamental I’m missing. It’s a Yamaha ARXA830 (which will shortly be being swapped for an Atmos compatible amp). All the DTS, DD and True HD boxes are ticked as the amp can do all of them.
