Audio 2.1 not working on toshiba laptop

[paulfromfr]

Hi everyone,

I just complete a fresh install of Ubuntu 12.04 on my Toshiba Qosmio F50-138.
I'm experiencing some trouble with the audio : My laptop has a built-in little sub-woofer that makes the global sound quite good.
In Ubuntu, I can't get to make this sub-woofer work. It is really annoying because without it, my laptop sounds quite crappy.

Does anyone have an idea of how i could get it to work ?

(PS : Sorry for my english, I'm from France, don't hesitate to correct me so that i can improve myself !)

Thanks
Paul
