Can you post the output of these terminal commands for me please:

Code:

uname -a
aplay -l
cat /proc/asound/version
head -n 1 /proc/asound/card*/codec#*

Terminal="Applications->Accessories->Terminal"
Please post text output using code tags. Also helpful is the make/model of your PC/Laptop.

OK. Update your kernel:

Code:

sudo apt-get update
sudo apt-get upgrade

Now reboot so we can work with the latest kernel.
Install alsa backports:

Code:

sudo apt-get install linux-backports-modules-alsa-lucid-generic

Reboot again.

Check your levels in alsamixer.

Code:

 alsamixer

Press F6 to select the correct soundcard.
Press F3 to show playback levels. F4 selects capture levels [or use <Tab>]
Use the left/right arrow keys to select and up/down arrow keys to change levels. <M> to mute/unmute.

Also try gnome-alsamixer and make sure to enable everything in 'Edit>Soundcard Properties'
