I do like to know why my xstream box is not allowing kodi to passthrough dolby true hd and dts hd contents. I configured everything in kodi and also tried switching between auto and manual surround options on the box. When I make it manual always sound is reporting as LPCM. My soundbar do support atmos and dts x and all other formats. Xstream box is connected to hdmi in on sound bar and soudbar to tv via arc. When I play contents from my laptop soundbar is able to pick up all formats.
