I have a Toshiba satellite U 840 laptop and recently a noise comes from the speakers when I play songs at high volume. Specially when I play songs with high bass level.
I don't have an Internal mic set up so that cannot be cause.
Really appreciate if anyone could help me
Since you say recently I assume that it was working without noise. Sounds like you over drove the speakers. Too loud with too much bass boost too long.
If they are internal then get external speakers. If they are external you may have damaged them with prolonged misuse. New speakers with more volume and base than the old ones would make sense.
