Yes, i have the C9 set to Pass-through. I’v tried both pass-through and auto, both allow Dolby ATMOS to pass-through but not DTS:X. I have noticed that there is a specific setting on the TV in the sound settings that toggles Dolby ATMOS on and off, and when you choose eARC Pass-through it become automatically selected to on.
