Hi, helpful forum! I made a similar thread to this some time ago, but this is kinda different.
I've setup my mpchc like in this guide here
. It gave me a prettty awesome picture quality, so I like that. However, my surround sound is bonkers. I don't get 5.1 sound, I get the same sound output on all channels. Voice is heard through all speakers and not through the center speaker for example.
