Speakers will not work with this program

Can someone please tell me why my speakers will not work with the basic program of Ulramixer? I thought my speakers were broken, but they are brand new and are connected to my laptop. They work with itunes and other programs, but not Ultamixer. When I start using this program, it will use the speakers but us the sound from my laptop speakers. Am I missing something? or need to do anything to get my speakers to work?

Thanks for the help!

Did you choose the right sound device in UltraMixer’s settings?

Went to the settings option and I got it to work, thanks!!!
