You need to check in the Settings Menu under "Video" that "Force DVI" is set to OFF. Dont forget to restart Box afterwards for changes to take effect.
there's neither forced nor dvi to do on off or otherwise!
The mag system really has a problem with some formats, such as those for movies or series in bluray format via DTS audio
I have several MAGs, even the very first one, they all have the same system concern that does not support all audio formats, which I find pathetic, and I have tested them on Android box via KODi, via other application system and even other brand of box, all they support audio sound regardless of the audio format.
The MAG system and their update are to be reviewed at the factory, and they must be tested before launching box on the market for sale.
We have to stop thinking people are idiots.
