I have no details and I'm not sure it really works either. I'm just sharing something I've seen in the internet ...

"For those of you who are interested, here’s a tip on the command line to manage the passthrough on the Mi Box S:

Enable developer options

adb connect <IP Mi box>: 5555
adb shell settings put global digital_sound 1
adb shell settings put global encoded_surround_output 2

encoded_surround_output 0 = auto (random behavior)
encoded_surround_output 1 = pcm
encoded_surround_output 2 = always

I recommend option 2 (always)"

Has someone tried that? Did it work? 

Registered just to say this helps!

I had a MiBox that I'd factory reset on 2573. As a result it had lost the 'Always' setting, just had 'Auto'. It could do DD 5.1 in Kodi, but no DD+. Netflix would not do DD+ either.

I soldered up a Male-Male cable, fired up adb, ran the commands, did a reboot and boom. DD+ working in Netflix. Thanks a heap!

Unfortunately, Kodi still does not do DD+ passthru, only DD 5.1. I have a Vodafone TV as well, and DD+ does not work in Kodi on that either.

Any tips?
