Hey,

I have the following setup with a Vanilla Catalina install (Clover EFI):

Gigabyte B360M AORUS Gaming 3
I5-9600kf
RX5500 XT
Broadcom bcm94331 (via PCI-e adapter)

Catalina detects both my Onboard Realtek Sound Card and the HDMI output adapter (it even lists my monitor as one of the audio outputs):

However, no audio output is really played via HDMI. Just for information, on the same machine, everything works fine on Windows 10.

These are the my Clover boot args:

-v -cdfon slide=0 agdpmod=pikera alcid=1

Any idea what else I could try to make it work?
I'm attaching here the IOREG file, KEXTCACHE output and my EFI folder.

Thanks

The same graphics card as you, can you now output sound through HDMI

No. TL;DR: Audio output works if I use the Display port, but it doesn't when I use only the HDMI port.

I couldn't find a way to fix this issue yet.

Hi, guys. I'm stuck on this issue with a similar build. Audio is ok, but I can't get any sound to external monitor speakers, even through the HDMI port. Any help?
