Is your MIC connected to the rear of the card?
(assuming it is):

How much are you boosting the MIC to hear it? How are you boosting the MIC volume?

What DSP config and kX Mixer settings are using?
(assuming you are using default config or similair):

Make sure the Master Recording level slider on the Recording page of kxmixer is at 100%. Crank up the AC97 recording level slider on the Recording page of kxmixer as the first step (if level is too low), as that will produce the least noise. Then try the MIC Boost option on the AC97 page of kxmixer (if necessary). Last (or if MIC boost is too much), try the Gain slider on the AC97 page of kxmixer.

BTW: The above affects the volume other people will hear you at, so you should be testing using loopback (i.e. test mode) within your chat client (i.e. normally you do not want to hear yourself in the speakers). With that in mind, make sure that the AC97 slider on the Ins and Outs page of kxmixer is muted (and the MIC In slider on the AC97 page of kxmixer).
