Okay, that looks like you don't use your mainboard's sound card, but an additional one, no?

However, I think that what I see here is actually a hardware thing. Maybe it's something about the built-in speakers my notbook has. As said, I have another Artix machine with a very similar setup, where HDMI audio worked out of the box. Perhaps, this one sends audio to both the analog and the HDMI output by default?

Well, after all, it works; one only has to take care of two output methods: On the one side, the direct ALSA output (used e.g. by mplayer) and on the other side the PulseAudio stuff (used by e.g. browsers).

No, snd_usb_audio is my webcam mic that I use for my YouTube videos.
My sound card is snd_hda_intel, the sound card on my motherboard.

I have already had the case on a laptop where the sound output was misdirected.

I'll let those who know answer.

That seems to be it.

With mplayer, I can play audio through HDMI by adding -ao alsa:device=hw=0.3, wthout having changed anything of ALSA's config. No chance for a browser (Falkon, Firefox, Chromium) though.

What I don't get is that mplayer can output through HDMI, and the browser stuff doesn't work.
This was your problem.

Well, as long as it works … a bit of fiddling around has to stay, this is Linux after all ;-)
