I suspect that ALSA's default output device on your machine is its analogue
output. What happens if you try running a regular browser with the Flash
plugin installed? Do you hear sound if you connect speakers/headphones
directly to the analogue output of your machine?

If I'm right, then you probably want to use a $HOME/.asoundrc (or
/etc/asound.conf to do it system-wide rather than for just one user) to
override the default output.  Something like:

pcm.!default {
       type plug
       slave.pcm {
               type hw
               card 0
               device 3
       }
  }

(assuming your HDMI output is device 3).

I find ALSA configuration quite complex and the documentation relatively
poor, so I wouldn't be at all surprised if someone chips in with a better
alternative for .asoundrc.

HTH,
