No HDMI audio device TV detected RX 570 AppleALC/VoodooHDA

No HDMI audio device TV detected RX 570 AppleALC/VoodooHDA

The device in question being a TV which I use just fine as a display. I had this working with Apple ALC on High Sierra + 1050 Ti. I am not sure whether it changed when I upgraded to Catalina or when I installed the RX 570, but now I am not getting any HDMI audio output devices listed. Instead, I've got this list of generic output devices which don't correlate with anything - these are not actual devices, I do not have 7 HDMI devices connected, and they don't go away if I disconnect the two ones I have.

Tried Voodoo HDA to see if it would be different. Same, I only get audio from my PC just speakers/headphone.
