I have a Sound Blaster Audigy 2 ZS sound card, and a 5.1 speaker system. I will be getting a small HDTV soon, and want to use my speaker system. the TV has an optical output, which I would need to have go into my computer. my sound card does not have this, so I was wondering what the best way would be for me to get this to work. if ther is another card that has an optical input please let me know, because I cannot find any. any ideas would help. Also, what is S/PDIF and is an optical SPDIF input the same as optical in?
