Windows 7 Microphone Settings
Follow these steps:
Step 1: Click on the Windows symbol in the bottom-left of the screen (square number 1 in the image below), and then click on control panel (square number 2 in the image below).
Step 2: Click on “Hardware and Sound”.
Step 3: Under “Sound” click on “Manage Audio Devices”.
Step 4: Click on the “Recording” tab.
Step 5: Now you will see a list of recording devices. Try speaking into your microphone, and look for green bars rising while you talk (see screenshot).
Step 6: If you have seen green bars rising while you spoke that means your microphone is properly configured (what to do if my microphone still isn’t working, even though you say it’s properly configured?)
Step 7: If you didn’t see any green bars while you spoke into the mic, keep following the instructions.
Step 8: See if you can recognize which one of the devices in the list is your microphone. Perform the next instructions for that one. If that doesn’t work or you’re not sure which device is your microphone, perform the instructions for all the devices one by one.
Step 9: Click on the relevant device to highlight it, and then click on “Set Default”.
Step 10: Double-click on the device and in the window that opens up click on the “Levels” tab.
Step 11: Drag the slider all the way to the right, until the number ‘100’ is displayed beside it.
Step 12: Click “OK”.
Step 13: Now check again if you see green bars rising when you talk into the microphone: if you do, your mic is now properly configured. If you tried following this procedure for all the devices but still don’t see any green bars, click here
