I just found a fix: In Windows 7 -> click on Start Menu and type 'Sound'. Go to the Sound Properties then click on 'Recording'. Open the properties of the microphone (if it is available) and change the boost to MAX (+40db). This should resolve your issue.
This worked for me. Good luck!
As the title states, the built-in mic on my Toshiba Satellite P305-S89151 Laptop does not work after upgrading to Windows 7 today. I did a Google search and saw that somene else with a TOshiba laptop was hving the same problems that I am, which brought me to here. Someone responded to his thread...
