Look in RECORD properties for the sound device. Where that is varies,
depending upon the device or card. To locate it, try a right-click on
the speaker icon (bottom-right of the screen).
Or open Control Panel|SOUND. You may see a RECORD tab, and can then
choose a device other than the mic, and click on SET AS DEFAULT.
You might also simply unplug the mic, if that option is available, or
perhaps disable the mic in RECORD properties.
