As per the issue description you are unable to use microphone of your LifeCam. The issue could be if some settings get wrong or drivers needed for the device is outdated/corrupted. Try the below mentioned steps and see if it works.

Method 1.

Try to run in-built troubleshooter and see if it works. An automated troubleshooter is a tool that can find and automatically fix some problems with your computer.
