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.
