I have been searching through the alsa-user archive and I have deemed that the reason I cannot hear any sound with my SoundBlaster Live! card is because it is sending an Analog signal to my Boston A.: Digital BA7500G speakers.
 
Is there a way to use a A/D converter or something to send a digital signal to the speakers? If so how would I do this? And what would I use?
 
Any help would be Great! Thanks.
