Hi,

have any of you managed to disable the internal mic on a Thinkpad? If
so, how?

During the last couple of days, the volume on the speakers is lower than
usual, and if I turn it up to the max, internal speakers and microphone
don't like each other (acoustic feedback? Please not I'm not a native
speaker).

Since I have a headset, I don't need the internal microphone. Is there
any way to disable it?

Thanks,
André
