Altera Stratix III and ALtera-Terasic HSMC Board: Access Audio ports

Hi!

I am working on a project titled, 'Melody Extraction from Polyphonic Music Signals'. For that I am using a Stratix III EP3SL150 board manufactured by Altera and a HSMC Daughter Card co-manufactured by terasic and Altera. I am having problems in accesing the audio ports, both mic and headphone. Could someone please help me out with this. I previously have not much of an experience working with Altera boards.

Thanks in advance for helping.
