Internal mic on thinkpad x201 (XP) has screeching feedback.
When the mic is turned mute (no way to totally disable), the result: nothing at all can be heard even though other features are not muted.
There is no separate setting for recording. Conexant controller is in- & out-audio.
How do I hear sound, stop the feedback & mute the mic all at once.
This problem just started today, after my cat walked across the keyboard.
