Last time, I got the problem with Audio Driver. Now It is Okay. But now,, I am playing a song, The voice is not clear (jib,,jib) like that. I can play song but not clear. But if I use headphone it is okay. I think it is not software problem, It is hard ware problem. How do you think about it? Without headphone, the song is really terrible. Maybe something is damage in my computer.
