So i have a Antec P180 and an X-Fi i was wondering on the case in the front there is a headphone and mic port, can i connect my soundcard to use those ports if so how?

AFAIK no. there are connections on your mobo, but not on your x-fi, there is usually only connections for a creative front panel, not compatable with your case ones.

No, you wont be able to, i have a p180 and X-fi and there is only the IO connector which connect via a ribbon cable... you cannot use the front audio ports with this card

Will this help.

If you can find the pinout for the X-Fi, you can make your own audio cable to carry the microphone ans headphone audio signals. Unfortunately, Creative likes to be a douchebag and reverse some of the signals (like the cable-insertion signal which would turn off your rear outputs) so they won't work properly with standard case audio jacks. I custom made a connector for my Audigy-2, but I never got my microphone to work properly, as I could not replicate the correct cable-insertion signal which would inform the sound card that the microphone was in fact plugged in. Sound quality may be sub-standard with a custom cable, unless you (or whoever makes the cable) does a clean job.

Edit:
Here is the pinout for the Audigy 2, which I have heard is the same as the X-Fi:
(pins in the small white box on the top edge of the card. IIRC, pins number right-to-left as you look at the front of the card)

1 - Analog Ground
2 - Analog Headphone Out Left
3 - Audio Backpanel Mute -- short to ground to mute the backpanel (when headphones are plugged in)
4 - Analog Headphone Out Right
5 - same as #3
6 - Mic input from front panel
7 - key pin (shouldn't be there)
8 - VREF out -- voltage reference for Mic
9 - MIC IN MUTE -- ground when mic isn't plugged in, +12VDC when mic is plugged in
10 - Audio cable detect -- will be ground when headphones are plugged in (not normally used)

For the headphones, connect audio ground to pin 1, left audio to pin 2, right audio to pin 5. For the mic, connect
mic in (or mic bias) to pin 6 and mic pwr to pin 8. Allegedly, if you connect pins 3 and 5 to the audio ground, you will mute the rear audio outputs when you plug your headphones in the front panel. Unfortunately, I have heard many reports that this has the opposite effect: the rear outputs are muted unless you plug your headphones in, which IMHO, defeats the purpose. Experiment at your own risk. Pin 9 is somehow involved in muting the rear mic input when a mic is plugged into the front panel, but I have not been able to figure out how this works.

To connect, you can either make your own connector or you can jerry-rig the existing FP audio connector. Here is a sample of a custom connector: http://img482.imageshack.us/my.php [...] modbq5.jpg Other people have had luck with inserting short copper wires into the FP audio connector's receptors, to keep a tight fit on the too-small pins of the X-Fi, and holding them in place with electrical tape. You can Google "X-Fi pinout" for more ideas on how to connect - many of the results deal with connecting to the front panel. Discussions of the 40 pin connector (like the link provided by 4ryan6), however, are not what you are looking for.

@ asgallant - thanks...i have had the pinout for years and used it...but i think its time to make that adapter....I just had mine crushed with pliers to fit
