Creative Sound Blaster X-Fi XtremeMusic Front Audio Question

I recently purchased the front audio port adapter from Performance-PCS (http://www.performance-pcs.com/catalog/index.php?main_page=product_info&cPath=83&products_id=21700) and when I plugged it into the AC' 97 pin header I lose my front right and rear right speakers. I then plugged it into the HD Audio pin header and I am able to get my headphones to work but the microphone will not work. Before I did this, I tested the mic on the rear port of the sound card and it functioned correctly. Has anyone had this problem before?
