.I am taking an online course and for requirement checks it says a microphone was not detected on your machine - most webcams have a built in microphone.

When I go to Control Panel under Hardware and Sound -- Sound then recording it says my Realtek high definition Audio is not plugged in.  WHAT DOES THIS MEAN --HELP

Have you installed the Updated driver for realtek HD audio?

In this case, it is highly recommended to run Playing Audio troubleshooter to detect the probable issues with the sound. To know how to do this, you can refer to the following link:
http://windows.microsoft.com/en-US/windows7/Open-the-Playing-Audio-troubleshooter

 

If the issue still persists, you need to check if you have the latest audio drivers installed on your computer. To do this, you can follow the steps below:

1. Go to http://us.acer.com/ac/en/US/content/drivers
2. Type Aspire 5517 in the box below "Search by Product Model" and click "Search".
3. Click on your model number from the list that comes up.
4. Once the details about your model are displayed, select your current operating system appropriately from the drop-down menu besides "Operating System".
5. Now, click on "Driver" tab and navigate to "Audio" in the "Category" column. Click "Download" (if you do not have the latest drivers installed already) and follow on-screen instructions to install the drivers.
