hey!! I'm having some issues running an external mic through my mac, on windows settings. The mic I am using is a plantronics, I'm not quite sure of the model. It has an audio in and an audio out connector. I have tried connecting to the audio in and switching the mic settings from internal to input, with no luck.. I guess my real question is: Is there anyway I can go about getting my mic to work with out having to buy an imic (http://www.griffintechnology.com/products/imic/) Sorry if this is a little vague. Thanks for the help!!
