SoundBlaster Live 24 bit question regarding microphone and digital speakers

​ I just got a brand new Dell Dimension 8400 with the SoundBlaster Live 24 bit sound card. My speakers are Boston Accoustic digital speakers w/ subwoofer. If I plug these speakers into the blue jack on my sound card everything works and sounds fine. My question is, where do I plug my microphone? I have tried the remaining three jacks (green, black, & yellow) and cant get the microphone to work on any of them. If I disconnect my digital speakers from the blue jack and plug my microphone into the blue jack, the microphone will work but I can't get my speakers to work on any of the other jacks. Help!!!! ​

The Blue jack is normally the "Line In" jack, not a speaker out and the microphone jack is Pink.  You must use the microphone jack for a "computer" mic (a standard P.A. or Karaoke mike will not work) as the computer mic requires a DC voltage to work and the mic jack is the only one that has the voltage.

The blue jack is Line In/Mic In or Digital I/O jack
 
The green jack is Line Out 1 jack
 
The black jack is Line Out 2 jack
 
The yellow jack is Line Out 3 jack
 
 
The diagram in my manual shows that connecting 2.1 digital channel speakers should go into the blue jack.  It says nothing about a microphone other than the description of the blue jack - Mic in.
 
Analog speakers would apparently be connected to the green black and yellow depending upon the number of speakers (I think).
 
Is it possible that there is some kind of adapter that I need to put into the blue jack that would accept a digital speaker lead and a microphone lead?
 
Once again Help!!!

This is what the Dell support section shows.  http://support.dell.com/support/edocs/acc/r45590/en/installc.htm
 
It goes along with what I have on the link I provided you.
 
One note, a computer microphone is a mono device, not stereo and the Tip is the signal and the  Ring on the jack is for DC voltage.  For other applications the jacks are Tip is one channel of stereo and the Ring is the other channel (I forget which is left and right), whether an Analog Input or Output.
 
I forget how the Digital (S/PDIF) output is wired.

There is NO Pink jack on the 24 bit Soundblaster. They are Blue,Green,Black and Yellow. The Microphone goes in the Blue Jack. My Speakers are in the Grey jack, but I only have the two standard Dell speakers.

 

I meant Green not Grey

Problem solved.  Fortunately, my subwoofer has a digital in and analog in jack.  I just had to dig out the old connecting cable and connect it to the green jack on the sound card.  Everything works great.  Thanks for the responses.
