Audio distorted on direct play in Shield

[RokuGuys 10]

I have this file when played in Shield pro, the audio is distorted on direct play  but it’s fixed through direct streaming. Under the Direct Play, it shows as 5.1 channels but the Direct  streaming shows 7.1 channels with the container being the same in both scenarios. (Mkv).  

Does that mean the file is incorrectly saved as 5.1 channels when it has 7.1 channels which is causing the error? It plays correctly in my Emby server running windows 10 though  the audio is rendered  as AAC while it’s originally DTS. I guess depending on the player it renders  differently?

Hi.  Can we please look at specifics for this playback, including a log from the app?

Thanks.
