Now mic works. I think there was priority problem with the sound system's mic entrance so i unplugged it and voila. For headphones i think the problem is unsolvable because of this priority thing, i guess. It always first gives the signal to stereo. Another question if I may, as you probably guessed, I had to remove and re-plug my jacks many times. Do you think that this might have caused a corrosion in the mick entrances because sometimes my mic does not give proper signal to system. Same thing goes for the headphones. Any ideas?
