Back feed on speaker of acer laptop

[kobus10]

Hello,I have a acer aspire 5741-3404 laptop and get bad feedback when I turn the volume up higher than 50% even power is unpluged.

Any advise?

Volume based feedback is normally caused by a "sound loop". In this case I might venture that your microphone sensitivity settings are too high. Try lowering your mic input, see if that helps.
