[ubuntu] Weird behaviour with my USB audio device, noisy audio, video inside

view story

http://ubuntuforums.org – Basically I have this Midiman M-Audio Fast Track MKII attached to my machine and when I play something the audio is "noisy". The strangest thing happens when I open the Sound Settings: the audio is playing correctly when the windows is open. Few seconds after I close it the weird sound comes back. I briefly tried from a live installation and the problem doesn't happen. And that's a video of what happens: http://www.youtube.com/watch?v=RdHcS...ature=youtu.be Kudos for the gentlemen willing to help (Hardware)
