USB Speakers Help
 

hi guys
I have this USB Speakers for my laptop
I can see it under Linux but the problem is that I can't find a place to set it as a default Audio Card ( the OS is dealing with it as an Audio Card ) !!!!
and the most important thing is that I need a software to give the speakers a boost ( make the sound lauder coz the normal sound is pretty low )
I have this software but it's only for Windows

the Speakers are made by a company called " OZAKI "

can anybody help me with this problem !!!!
