   Can you refresh me with your setup info?

cat /proc/asound/cards
cat /etc/modprobe.conf

I've never run into problems with Firefox not producing audio. One
problem I have seen is issues around the sound chip not being willing
to change sample rates and hence audio not playing. (For instance, the
web audio is 32KHz and the sound chip is locked to 48KHz.

On paper they tell me you can get around this with the plughw
construst, which you seem to be using, but possibly you need an entry
inyour .asoundrc file for the first card, or possibly somethign
special in the way you load the modules.

Anyway, pass backa  little more info and maybe Fernando or someone
else here will have a better answer.

Good luck,
