Sound Advice

Hi,

I would like to get my sound card working correctly (using all 4.1 speakers) 
but I can't seem to figure out how. I have a GigaByte GA-K8NXP-SLI 
motherboard with a built in RealTec ALC850 sound chip. At the moment I get 
sound but only from 2.1 speakers. I think these drivers

http://www.realtek.com.tw/downloads/dlac97-2.aspx?lineid=5&famid=12&series=8&Software=True#8Unix%20
(Linux)

would make it work but before I go and screw up my system trying to get them 
installed is there a Debian way of installing / setting up these drivers?

lsmod shows the following sound related modules are installed

snd_intel8x0           35904  0
snd_ac97_codec         88836  1 snd_intel8x0
snd_pcm_oss            56544  0
snd_mixer_oss          19072  1 snd_pcm_oss

I have a feeling that the first one is actually the correct driver. If it is 
then how do I get all the speakers working?

Many thanks,

Graham
