Getting a high pitched sound when I turn up volume?

[blank.black]

The laptop in this case is a Acer Aspire 5050 (bought at Walmart about 3-4 years ago).

I turn the volume up and when i get close to about half way on the volume bar, i start hearing this high pitched whistle-like sound which gets louder the more you turn it up. The sound is continuous so I am not able to turn up the volume up higher than 50% or so which is not loud enough.

So what is the problem here and how can I fix this? Please Help...

Hmmm. Since it is not longer under warranty you can't send it in so maybe this could help. Plug in some external speakers and see if this is a hardware problem. If the external speakers don't make a noise then shop around on the internet and see if you can find some replacement speakers. The swap wouldn't be all that hard. If the external speakers also make the noise you can try updating your drivers at the Acer website and see if that has any affect.

Let me know what happens.

i do not have external speakers but i tried headphones but it did not seem like i was receiving much sound through headphones. it mainly seemed to come from the actual body itself.

i turned it on just now and barely got the volume up when it made that sound again and just froze. so i could not get the volume bar down and ended shutting down the lid and pulling the battery out which finally made it stop. :(

It froze? Your hard drive may be dieing, or your cpu fan may be in its death throws. This could possibly be mistaken for the speakers dieing. Perhaps a short that is causing the noise? Maybe one of the PF electrical engineers could point out whether or not that is possible. How hard would it be for you to confirm whether it was your hard drive or not? Does the sound happen when your speakers are off?
