DTS-HD MA not playing

[Kihikihi]

@JimKnopf

You’ve to connect the TV’s eARC/ARC HDMI port (it’s called HDMI IN 3) with eARC/ARC HDMI out port of the soundbar and the Vero with the HDMI 1 or 2 port of the soundbar. Of cause you’ve to use appropriate HDMI cables.

If you want to watch the signal from the Vero, you have to switch to the appropriate input on the soundbar (using HDMI 1 or HDM2 button on the soundbar’s remote control) and switch the TV’s input to HDMI IN 3 (using the INPUT button on the TV’s remote control).

Well, bugger me. That did it!!
Apparently it did not occur to me to connect the Vero to the soundbar first, and then let the eARC channel send the picture to the TV - not really unusual if you consider the soundbar is just a simplified AVR…which I seemed to have forgotten.
Just to confirm, here is the relevant page from the manual:

Thanks again @JimKnopf for helping me figure this out!
