Hey, I'm having trouble getting surround sound off my MiBox.
I use HDMI ARC and Netflix only gets Stereo 2.0. Has anyone tried the S/PDIF and successfully getting 5.1 surround?
Also I enjoyed how Fire TV only enables 4K when it needs to eg Netflix, Youtube 4K etc. so other HD content can be upscaled by the TV.
What type of sound system are you using on the receiving end of the HDMI ARC? Does it support DD+? Many soundbar 5.1 systems older than a year or so do not support DD+ and if the MiBox doesn't automatically downconvert to DD then you get Stereo sound as a result.
