The video chat program Skype has a built-in feature known as automatic gain control (AGC). This feature automatically adjusts the sound level of your microphone when you are using Skype. AGC sometimes adjusts the volume so low that the person to whom you are talking can't hear you. Because AGC is an automatic feature, you can't adjust the microphone volume manually without a bit of tweaking.

Skill level:


  1. 1

    Open the Skype program on your computer. Click the "Tools" option on the Skype menu bar and select "Options."

  2. 2

    Click "Sound Devices." Remove the check mark from the box labelled "Let Skype Adjust My Sound Device Settings." If you are running AGC Version 2 or higher, instead remove the check mark from the box labelled "Enable Automatic Sound Device Adjustment Settings."

  3. 3

    Click "Save" to save your changes. Close Skype.

  4. 4

    Type "%AppData%\Skype" in the address bar of your Internet browser. Press "Enter" on your keyboard. You will see all of the folders related to the Skype program.

  5. 5

    Double-click the folder that displays your Skype username. Right-click the "config.xml" file. Select the option to open the file using Notepad. If you are using Skype AGC Version 2 or higher, don't look for the Skype username folder. Instead, right-click on the "share.xml" file. Select the option to open the file using Notepad.

  6. 6

    Locate the code that appears as follows:






  7. 7

    Edit the "Call" and "General" code so that it appears as follows:






    If you are running AGC version 2 or higher, add the following code in Notepad.



  8. 8

    Click "File" and "Save" from the top menu bar to save your changes to the Skype code. Open your Skype program to begin talking again.

    If you need to adjust the volume while you are talking, click the volume control icon in your computer's system tray. You can drag the volume bar up or down as necessary until you find the volume level that is best for you.
