I finally have 4k working on my Mi Box now after some hdcp issues. Now my only problem left ist that Netflix won't output 5.1 audio.
Here is my setup:
MI Box hooked up to my Philips 43puk7100 TV directly via hdmi.
My TV connected to my (pretty old) Yamaha receiver via optical cable.
I know my receiver can't handle dd+ or TrueHD audio.
However when using the Netflix app on my Windows computer hooked up over the same connection netflix can output 5.1 audio, I just can't get it to work on my Mi Box.
Is it my receiver? Can netflix even tell the receivers capabilities if it's connected to it trough my TV and the optical cable? AFAIK toslink is a one way connection...
Kodi and plex work with 5.1 sound without any issues.
i have the same issue too. tried directly connecting via optical to the Yamaha and through the TV HDMI but no luck. i hope the android N update fixes this.
