I´ve bought a Sony Home Theater In a Box HT-DDW750, and I´d like to connect my PC to have 5.1 sound from my PC-DVD player. For that I´d have to buy a 5.1 soundcard that had a digital optical output, cause that´s the only digital connection that´s avaliable here. Seems to me that Soundblaster Live! 5.1 doesn´t have a digital output, is there any option to connect it to the receiver with simple RCA cable and have a good 5.1 sound?(I can´t recognize a single output for doing this, just the sound boxes outputs...) Which are the best soundcard that have digital optical output?(Price is really a problem here... TIA Hope some answers soon!
