It only has three slots . One is the Microphone, the other is blue, and the other is green. Is it possible to make my blue port work for my speakers? It won't work with my new headset . http://www.logitech.com/index.cfm/products...,CONTENTID=9523 It's either, speakers/mic, or headset/mic. How would I go about making both of them work at the same time?
