AMD Radeon RX 5500 XT no Audio over HDMI

[surfbum]

Hi I've recently set up my rig and its going really well. The only annoyance is I cannot figure out how to get audio over HDMI.
I've tested the setup using Windows and Ubuntu and it works perfectly so its something in the setup.
Audio works fine through Motherboard speaker plug and over USB.

Any help is appreciated.
I've used Opencore 0.6.3
CPU - i5 10400
Motherboard - Gigabyte B460M Gaming HD
dGPU - Sapphire AMD Radeon RX 5500 XT 8gb.

Thanks

I have the same motherboard, and i cant usb to work, are you using clover or opencore?
can you send me the EFI you use on catalina?

USB worked fine for me and the resolution for audio was a display port adaptor to hdmi. I don’t have the EFI anymore sorry. Used open ore and followed their USB mapping. But worked before mapping also.
