Which make, and model of Laptop/PC are you using?

Will you post the output of the following commands please.

cat /proc/asound/cards
grep ^Codec /proc/asound/card?/codec*
/sbin/lspci -vn          (just the part for the soundcard)
/sbin/lsmod | grep snd

Have a look at the settings for alsamixer in Gnomes terminal, or if your using 
KDE, use KDE's Konsole. Type the following command to get all alsamixer 
controls.

alsamixer -D hw:0

Check for controls that are muted (the M key toggles mute/unmute), and push up 
sliders like, Master, PCM, Front, CD, which are the usual ones needed to get 
some sound output.

Best wishes.

Nigel.
