I just bought the Logitech X-530 5.1 speakers, and the Sound Blaster Live 24 bit Sound card. I have hooked everything up but yet only the front two speakers work. I do the diag. and everything works out, I then do the "Test Speakers" where a voice comes out of each speaker saying "Front left", "Front Center" and such. All 5 of the speakers will have the voice come out them correctly. But when I try and play a song or a game the front two speakers work and the sub, but all of the others are silent. Any Help¿?
