Ah, that looks as if the default device is set to use the "pulse"
plugin then. If your distribution did that system-whide,
your /etc/asound.conf might contain something like

pcm.!default {
    type pulse
ctl.!default {
    type pulse

(or maybe they put a .asoundrc in /etc/skel, then you should have it in

So try commenting it out, paulseaudio -k, and aplay again.
"cat /proc/asound/cards" shows the current order of your devices, so

aplay -Dhw:0 == card 0
aplay -Dhw:1 == card 1

Those HDMI jacks contain both, audio and video signal output.
