Asus x52de laptop: where does the noise in the headphones come from?

Question

Audio

When you connect any headphones or external speakers, an incomprehensible noise appears, similar to the robot of an old dot matrix printer. This was observed with any OS, I tried: XP, 7, several Linux. It appears only after something is played, that is, if there is no sound source and headphones are connected, then there will be no noise, but if you turn on any media file, noise will start and will not stop anymore, even after playback stops.
Notebook Asus x52de, now stands W7. Please, help.

Answer 1

Only with headphones? Through the columns everything is OK?
Clearly not a software problem. If under warranty, go to the service. If not, it will be cheaper to buy an external USB stick.
