Only regular DTS over RAW Packer?



Hi!
So I’m getting only regular DTS when using the Android RAW Packer, even though the DTS-HD receiver support is checked. When playing a DTS:X file for example it reverts to regular 5.1 DTS everytime.
When using the Kodi Packer DTS-HD and DTS:X are both working, but the Kodi Packer causes audio sync issues with some video files, so I prefer to use the RAW Packer.
I was wondering if this is a known issue or if there is anything wrong with my setup/settings. Also why the Kodi Packer causes out of sync issues with a few video files.  Couldn’t find any setting that fixes this.
Maybe any of it was fixed in a nightly build? Currently using the stable release.

Setup:
Kodi 21.1 Stable
Fire Cube Gen3
Samsung Q930C Soundbar via Passthrough (all formats supported)
