@bradipo Hi, I don’t know how much you love your old AVR and what budget you are willing to take in hand but give this topic a look: HDMI audio passthrough LG B6P? - #6 by JimKnopf
The HDFury AVRKey splits the HDMI 4k signal to an HDMI pass-through and a HDMI 720p/1080p with full audio, so you can split the Vero’s output to the 4k TV and the AVR. But costs some bucks, in German Ama…n around 150,- EUR or as used part around 110-120, EUR.
