[Hank Smith, and Seeing-eye dog Iona]

Hello
I have the soundblaster xfi
can any one tell me what opticle audio  are on the card and where the 
optical input is at?
I would need the info going from right to left the plug on the right is 
the microphone/line in jack.
I just got the contoorer2 box with the talking voice guidance
that is identicle to the comcast voice guidance
they just launched the talking feature to the contoorer 2 boxes a little 
over a month ago.
