Hi!
I'm running Fedora 30, kernel 5.1.19 and I can't seem to get audio output through HDMI or DisplayPort.

aplay -l gives me:

In the other end of the HDMI and DisplayPort cables I have one monitor each that I have plugged in a headphone to (Yes, I've connected a headphone to each to test this out)
