Right speaker stopped working .

I was using a pair of Logitech speakers . I upgraded it to a Samsung 2.1 speaker . From that , My right speaker functionality is broken . I tried both the speakers with my laptop . they are in good condition and works perfectly . It does not work in the PC . I tested it in the configure option , the right one is not functioning . All drivers are up to date and no yellow symbol in device manager . Help me out .
