I have a 2012 Mac Mini hooked up to my Yamaha receiver via HDMI (and then to my TV from the receiver, obviously). Anyway, I'm trying to get my MKV videos to play in 5.1 digital encoded audio via VLC 2.0.5 (latest stable version, I believe). If I play the videos in Plex, they play perfectly and it sends the encoded audio correctly (the receiver will show DTS, Dolby, etc). When I am not playing a movie (just using the Mac Mini normally), my receiver shows PCM with 5 channels on. I believe this is fine since no encoded audio is being send to the receiver at that time. However, when I play the same MKV videos in VLC, it stays on PCM. If I go to the Audio menu and select "HDMI Encoded", then I get no sound at all and my receiver shows "Decoder Off". I think this is where the problem lies because VLC should not be sending encoded audio and my receiver should be showing the correct format (DTS, Dolby, etc). Any suggestions on how to get HDMI Encoded working? Is there some other setting in VLC or in my Mac settings that I need to set? Thanks!
