mic recording volume very low

hi all,
im having trouble with my headphones mic which from some reason recording volume is very low .
so low that in game (by using TS [teamspeak]) when other people have the game sound , they can bearly hear me.
i set my mic to 100 volume and the boost to +30db but thing stay the same.

when i test the mic with recorder the bar even dont rised a little bit .

ohh , and by the way , in case anyone thought the problem isnt in the mic which is new due to the fact that after this problem happend at the last microsoft headphones i had, i bought new one (forgot the model).
any help here ?

im using windows 7
64bit premium

its a creative (headphone with mic on it).
i have 2 input for the mic . one at the front of my pc tower and second on the back.
both record the same.
when i plugin the mic line i get pop up windows which prompt on a mic connection.

any more ideas ?
i will look at creative web site.

thanx
