Would've done that, but I wouldn't have wanted to be shunned for asking an
oft-asked question, since you said this issue was answered multiple times
before.

Exactly how do you think I got to post on alsa's bug report and alsa-user
mailing lists?
I asked a completely different question by the way.

Don't have an ~/.asoundrc, so I'll assume I have to do that to
/etc/asound.conf

That's exactly the same as configuartion #2 that I've tried, and which
didn't work... Read my initial message in this bug report, please.
But I gave it a spin this time again, in case I messed up something last
time (and I did, just not with ALSA).

That gives me:
Failed to restart alsa-utils.service: Unit alsa-utils.service is masked.

So I used this instead:

# /etc/init.d/alsa-utils restart

Which unfortunately didn't seem to change anything, so probably the command
I issued didn't work.
But after restarting, the sound was the same, but I found out what was
causing all these issues:
In VLC I've set up a custom device for audio output instead of "Default",
and that seemed to hold the sound blocked to one app. After changing it
back to "Default", everything works as expected (multiple sound sources,
browser add-ons sounds work, WebM/HTML5 players have sound)

This can be now closed as it's no longer a bug. The message about missing
files led me to think that the ALSA package I got was broken, thus the bug
report.
