Hi Zheck. You say soundcard, but 2 cards are showing. Would you confirm how 
many soundcards you actually have? Perhaps an onboard one plus the c-media 
one maybe. If 2 cards, which one do you want to get working first?

Would you post the output of the following commands please.

cat /proc/asound/cards
cat /proc/asound/version
lsmod | grep snd
lspci -v       (just the bits for the soundcard/s will do here)

Open a terminal, and as user type, alsamixer . Which should show you the 
settings for the default card (card0). there may be something muted, or a 
slider just needs to be pushed up. To unmute controls that are muted, use the 
M key, which will toggle mute/unmute.

If you want to see alsamixer for card1, type, alsamixer -c 1, and that should 
show controls for c-media one.

The ESC key will exit alsamixer. See, man alsamixer for other usefull stuff.

All the best.

Nigel.
