Audio :: Sound Suddenly Disappears If Too Loud When Playing Videos Or Games

While playing a video or games or any app that has sound... the sound suddenly disappears if it is too loud. At first I thought it might be the driver... so i replaced HD Audio with Conexant... but the problem still persists, which lead me to believe that it could be probably the speaker's problem.

But while tweaking around I found that if i quit the video or the game, the sound came back to normal. And also when the sound goes off,the green bar on the volume tray icon still keeps jumping up and down indicating sound output. Hence audio troubleshooter was of no use.

When i opened volume properties,playback devices (a video playing in the background where the sound had gone off),as i switched between the tabs in the dialog box (playbackrecording,sounds,communincation) the sound came back! This cannot be due to the speaker.

I have reinstalled windows8, updated drivers and everything but no effect. What to do, as i cannot see movies or play games with speaker. Also headphones and external speakers have no problem whatsoever.
