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 reference: https://help.ubuntu.com/community/HowToJACKConfiguration and maybe this for the whole system set up: https://help.ubuntu.com/community/UbuntuStudioPreparation) 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 system. 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. -- Ubuntu-Studio-users mailing list Ubuntu-Studio-users@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-studio-users
