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)
