i had a sharp noise coming from my new sony vaioFE21B laptop speakers..even when i tap gently with my fingers near my mic socket..it gives a sound in the speakers.....cant use the laptop at the maximum level...or the sharp noise comes out...
had to send it back to sony for repair
they say it is some larson effect..but my friends witht the same laptop does not have that problem
even i did not have that problem before..just started a few days ago.....not happy with the support service priovided by sony

Hi rajivmaureen,

Welcome to Club vaio,

According to the specs for your Fe21B, your model comes with an internal microphone, is it possible this noise is caused by the microphone picking up the sound from your speakers...:smileyconfused:

rajivmaureen,

The problem you're describing doesn't sound like a fault with the laptop. It sounds to me that your problem is just that you have some application running which is activating the built in mic and routing the sound directly to the speakers - as Thalamus has suggested.

If so, the sharp noise that results at higher volume levels is just feedback - i.e. the endless loop where the mic picks up the speaker noise - feeds it back to the speakers - which feeds it back to the mic ..etc Gradually increasing to a high pitched whine.

Regards.
