Your config looks sane to me (though specifying something as 'type hw' can interfere with mixing sometimes; an empty or non-existent ~/.asoundrc should default to dmix internally. I doubt this is your problem though since it works on everything else)
Here's an idea: try using the ALSA_CARD environment variable and run
Firefox with it. All you'll need is the name of your card. So if your
card is named "Onboard", you'd issue this:
ALSA_CARD="Onboard" firefox
in a terminal, go to Youtube, and check stdout in the terminal.
You can check for your card names with this pipeline:
aplay -l | awk '/^card/{print$3}' | sort | uniq
For me, my primary card is "SB", which is onboard Intel HDA.
If you can get $ALSA_CARD to work, then we know firefox itself can play
sound, but somehow isn't defaulting to the device you want it to. Back
when I used ALSA + apulse (and intend to do so again some time in the
future...), I used $ALSA_CARD for some programs that misbehaved and
things were okay.
If this persists as a problem for you, it might be worth opening a bug
for it, as what I've shared is as far as my personal experience goes and
other people may be experiencing the same issue. You'll need to provide
'emerge --info' and possibly 'emerge -pv firefox' output if you choose
to report a bug.
Let me know how it goes.
