Audigy LS and Ubuntu

[Bnonn]

Hi everyone, I have a Creative Soundblaster Audigy LS which I'm trying 
to get working in Ubuntu. I understand that the LS is supported by Alsa 
1.0.7. Since I had installed Warty (which comes with 1.0.5), I added all 
of Hoary's repos to my repo list, and did an apt-get update && apt-get 
upgrade && apt-get dist-upgrade (whether or not this means I am 
technically running Hoary now I am not entirely certain; could someone 
clarify?)

Synaptic now lists my current Alsa version as being 1.0.7, which is what 
I need for Audigy LS support, however I'm not sure what else I need to 
do to get Ubuntu to recognize the soundcard and load the drivers for it. 
Alsamixer currently only shows my BT TV card. The soundcard shows up ok 
in the device manager, and I know it's working. I'm just not sure what 
manual steps are needed to configure it correctly.

Can anyone help?
