Hi TBuck5,
Welcome to the HPCommunity, I hope you enjoy your experience! To help you get the most out of the HP Forums I would like to direct your attention to the HP Forums Guide First Time Here? Learn How to Post and More.
I will be happy to assist you with the audio issue you are experiencing. I will need to know what your product number is as there are several models in the g6 series. Also make sure that your microphone is set as the default recording device. This link will show you how to do it. It will be about half way done the link and it is for Windows 7 but if you search for Control Panel on the tile screen and then go into Sound from there the rest of the steps are the same.
Thank you,
