Hello Giuliano! 

(I have written this mail some 3 hours ago before your last reply and saved it 
for further editing. Nevertheless I send it now in case there is something 
that can help you. :) )

Eventhough I have only very little experience with ubuntu studio applications 
(just last week I set up my realtime kernel and system and it works perfectly 
with a very cheap usb audio interface of 12€!), I want to share it with you.

You should work with Jack! Install it (as Pablo said, it's gui is called 
"qjackctl"), and make a good setup for your system. (I used this for 
and maybe this for the whole system set up: 

In the case that there is no problem with your audio card drivers (I can't 
help you here!) and Jack is configured properly, then you should hear sound 
form your card. In other words and since as you said you card is recognized 
from your system, if the sound isn't working, then you haven't configured Jack 
properly. In the setup menu of qjackctl , at the Settings tab you should try 
all possible settings, especially play with the "driver", "interface", "input 
device" and "output device", in order to make the right configuration of your 

Normally, you will see your audio interface's name at the "interface" and 
"input and output device" options. Play with these, save your settings and hit 
"start" at the main window of Qjackctl to start the engine.
