Yes, that helped. From the aplay command (see further below), I put this
in my ~/.asoundrc:
$> cat ~/.asoundrc
pcm.!default front:default

and then restarted Mozilla browser and its video's then used the headset
for audio. So that went well. However, audacious still play audio from
the internal card. I am not sure how the .asoundrc is supposed to work.
Doesn't it just send all audio to the one selected in it?

Thanks.
Regards.
