Screeching on laptop speakers

  EFC1878 14:39 23 Aug 11

I have a Toshiba laptop and up until recently I have had no problems. However after playing music I heard an awful screeching noise. Now I find that if the speakers volume setting is low it aoppears fine but when I take the volume a little higher [to the half way point] a terrible screeching nows is heard.

I don't know if I have played the musioc too loud and damaged the speakers - but surely this would occur at all volumes wouldn't it? or if it is either a hardware or software fault. Somebody suggested that I may need to download knew drivers and tnhat may resolve the problem.

Any ideas?

Is the mic muted?

As far as I can see this is the THIRD time you've posted the same question.

Multiple posts won't get you a quicker answer but it will probably annoy members.

No the mic is not muted. Can hear sound ok at low volume level then at a higher level the screeching starts

I got an error message when submitting post so resubmitted - it was an innocent mistake and not an intentional multi-postiongn

When the speakers screech tap the top of the lid where the web camera/mic is and if you can here the tapping through the speakers the mic is on, or lower the lid when it is not screeching and if it starts screeching confirms mic on.

Mute the mic. It's probably feedback.

Classic Feedback symptoms.

Turn the Microphone's sensitivity down, you should not really need to turn it off but, on the other hand, there is really little point in having it 'On' when it's not in use.

How do I tell if the mic is on? I am using Windows 7

I think you are right about the feedback. Not sure what I have done to turn the mic on however could you advise how to turn the mic off?

I haven't got W7 but it should be through your sound properties in control panel.
