Problem with Tascam US-200 sound card

Hello
I have installed Mageia 4 recently and i have to say that it is the best linux (i started with Mandriva 2006 before many years, i used many many distros but mainly windows).
I use Tascam US-200 sound card (http://www.tascam.eu/en/us-200.html) because is better then "on board" (i am DJ / Producer) and i dont have sound.
What can i do?
Thank you
