Dear Maintainer,

I have a Radeon RX580 card with two DisplayPort ports, in a dual-head monitor
setup. When I look at the corresponding audio sink with pulseaudio, however, I
find that there is only one output port listed, and so I cannot select which
port I wish to send audio out on.

Both ports work for audio; if the current-active monitor is disconnected, then
the audio will automatically switch to the other one. It is just that they are
not both exposed simultaneously to pulseaudio as being selectable.
