I've got a similar configuation working under xfce4 without
pulseaudio. My trick was to get it working at the command-line using
aplay. I got a list of my devices (aplay -l) and then would play a
simple wav file out each device until I found the right output for
HDMI. I've attached my asoundrc with some comments. Basically, keep
changing the device until aplay makes sound come out. After that,
Flash just worked for me.

Hope this helps!
