DTS-HD MA passthrough

Noob here. I have installed CE on Beelink GT King Pro few days ago. I am using LG soundbar (SP8YA with rear speaker setup) and this android box is connected to soundbar’s HDMI input because my TV does not have e-ARC. Soundbar’s e-ARC output is connected to ARC input of the TV. It’s working fine with the appropriate DTB. Dolby Atmos and DTS:X shown on the display if play those files. TrueHD and DTS-HD also playing fine but not shown in the display, i have to press a button on the remote to find out the output codec. They are shown as Dolby Audio and DTS Audio, respectively.

The issue i have is DTS-HD MA output. For example I am seeing input dtshd-ma and pt-dtshd on the player tab. I have good surround coming out from the speakers but i am not sure its actually DTS-HD MA or its being down mixed to DTS-HD. Its also shown as DTS Audio. Can someone help to clear this? The soundbar is capable of playing DTS-HD MA input. Thanks.

a google search suggests that Master HD isn’t supported by ARC so I presume you just get the standard DTS instead.

Its true ARC in TV won’t decode HD sounds. My device connected to Soundbar, not TV. TrueHD, DTS:X works in this setup. Only DTS-HD Master Audio is being downmixed to DTS-HD and this is what I am talking about.

Is it selected in kodi audio settings?

Are you referring to the Audio Output? Yes, its selected.
