how do i get the audio to work?

[smart_not]

I am using a touch screen computer much like commercial ones you would find in a restaurant or convenient store. It has a logo that says "CE" and "UL" and on the back and it says model:MP5000. On this computer I'm using Ubuntu. I tried hooking up two different sets of speakers and I still do not hear any sound. I have also double checked volume control and audio settings and it tells me that nothing is wrong. any ideas?

lets try to see what audio card you have
open up terminal and execute these, post results

lspci | grep -i audio
lsmod | grep snd
