I had the same problem. I have audio over HDMI and everything worked except
for flash/hulu/firefox and fixed it by changing the default definition.
These programs use ALSA's default output and ALSA sets the default output to
card 0, device 0 unless told otherwise. Try changing your asound.conf to

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