Just a quick reply to say after updating I have the same issue. I’ve switched it to the HDMI device only (rather than HDMI, S/P-DIF and analogue) and touch wood it’s working. I’m the same Vero 4K+ into a Denon AVR-X4500H. I have a separate issue with HD video (1080p24 and 1080i50) now being jerky but I’ll raise that separately when I have time to grab logs.
