The sound driver seems to be up to date. Nothing wrong with the speaker because I tried it on my laptop and its totally fine. So, i guess its the mobo jack. Although my old speakers worked fine. (I do not have any sound card. Currently using on board card.)
What can you suggest me?

Have you check the sound settings in the Control Panel?
Yes, I have done possibly everything related to software. Nothing works. Expect something new suggested.
