Hi, I bought recently this box for unified experience (using netflix and hbo go). Almost everything is ok, except there is no 5.1 audio tracks on netflix. Mi box S is connected to my old yamaha rv450 thru toslink (similiar to this https://b.allegroimg.com/original/01ab4f/f76b18604995bc3a092ab77ccdab). However I can play demo 5.1 files from Kodi (with passtrough setting on). My ampli reads audio as 5.1 correctly.
You can see my mi box settings here https://drive.google.com/drive/folders/1gVGcRJNpZb_UwwgpCUlhvSJ_ql5JNoMf?usp=sharing
You can also see photos from Xbox One and mi box on same movie. Why netflix not let my mi box see 5.1 audio track?
ps. In audio settings I can only pick between PCM or Auto, someone asking about always option - there is no such option.
