Does your headset work when connecting to your I/O panel on the back of your PC? What do you mean "checked in board it is conected"...No clue what you're trying to say there. Do you have the front panel connected to the mobo?
Sometimes when connecting the front panel cable to mobo the 4pin or 5pin connection can be connected backwards. Which would rendering it inoperable do to no power.
If you could fill in your system specs in your profile area, this will help us with the hardware side of the issue.
