After much searching, I finally found the answer to this dilemma. My case have the AC '97 audio cables and all I had to do is disconnect these cables from the motherboard. While I am not able to use the front headphone and mic jacks, I can use the back audio jacks (which is fine with me as long as the mic works). For future references to those who have AC' 97 audio cables in their computer case, below is the correct settings for connecting those cables to your Intel motherboard.
Pin Signal Name Pin Signal Name
1 MIC 2 AUD_GND
3 MIC_BIAS 4 AUD_GND
5 FP_OUT_R 6 FP_RETURN_R
7 AUD_5V 8 KEY
9 FP_OUT_L 10 FP_RETURN_L
I hope this help someone and good luck!!!
