@Isaac_Spear - I suspect that you have a chain of HDMI devices: Nucleus → Anthem → Smart TV.

It’s probably the Smart TV that is causing an EDID handshake issue with the Nucleus. I had this issue when we replaced a Panasonic TV with a Samsung TV

And have there been any changes recently. I say this because my ROCK/NUC worked faultlessly with my Denon AVR when the latter was connected to a Panasonic TV. When we replaced this with a Samsung TV, the HDMI handshaking across the NUC → Denon → TV broke on a regular basis. I had to invest in a [Doctor HDMI](https://drhdmi.eu/DR-HDMI/) device between the NUC and …

I believe that I just have the Dr. HDMI device set to its simplest HD setting (1920x1080) - nothing to do with audio formats.
