Ugoos AMB6 plus (DTS-HD not sound)

Hello everyone,
I recently installed my Ugoos AM6B Plus, and I encountered an issue while trying to play movies with DTS-HD audio (no sound at all). On the other hand, Dolby Atmos TrueHD plays without any problems.

CoreELEC Version:
21.1.1-Omega-Generic

Ugoos Firmware Version:
0.5.4n

Here is an example of an MKV file I tried to play without success:

Setup:
Ugoos AM6B Plus → TV → Soundbar

I tested two different configurations with the same result:
Sony 55X900H (2020) + Sonos ARC
Sony A80J + HT-A7000

This is my configuration:
