Hi guys, new here. Im interested in getting the new MI box S, but reading some pages here it seems it got lots of audio issues. My question is, passthrough audio to receiver, like dts-hd or atmos were never compatible or just broken by xiaomi's oreo firmware? are there any other recommended boxes besides the nvidia shield for having hd audio passthrough ?

 Hi,

I am new here too. I got the Mi Box 3 a few days ago and it self-updated to Oreo version 2396. I'll try to answer your questions.

Here's the bad news:

1. for some reason, when playing back a 1080p or 4k movie from a USB drive, the audio will randomly cut out for a second. This may happen twice during a 1.5 hour movie or four times. I can replay the entire file and the audio drops will not occur in the same place. Sometimes, there will be a soft burst of audio static for no apparent reason. I know it's not a file problem because the file plays perfectly on my HTPC with no audio static or audio drops;
   
2. there is no auto frame rate switching which is bad when playing a movie with a 23.976 or 24 FPS rate while the desktop is set to 2160p/60. This will cause dropped frames or stuttering even in Kodi with the frame change option enabled. I notice it while others may not; and
   
3. there was a bit of stuttering in Netflix 4k but I didn't notice many instances of frame drops; however, that may have been a function of the show I was watching.
   

Here's the good news:

1. 1080 and 4k files from my USB drive look pretty good;
   
2. using Kodi Leia 18 RC and my 5.1 system, I see TrueHD and DTS-HD MA on my receiver's display panel. I assume it will pass the meta data for Atmos and DTS-X as well but I don't know for sure since I don't have an Atmos-compatible system;
   
3. I get Netflix 4k HDR with no problem; and
   
4. no audio drop outs when using Netflix at 4k with DD+ 5.1.
   

Xiaomi is supposedly working on auto frame rate switching which would eliminate the stuttering and, hopefully, audio drops.

I hope the information I have included is helpful.  

 can you please share your kodi settings.. and mi box audio settings. i can not seem to get dts hd and true hd out of my mi box s. using yamaha 681 receiver which supports atmos too .
