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
What To Do If You Did See Green Bards Moving But Your Microphone Still Isn't Working In Some Program
If that's the case then you now know that Windows is configured correctly and can "hear" your microphone, but the program you're using can't. (to verify that, check your microphone with your mic test tool - and you'll see that the browser is detecting the input from the microphone).
The program you're working with might be listening to the wrong microphone. Try to play with its settings to find how to make it listen to the right mic, and contact its support team if needed.
If you followed the steps but still don't see any green bars:
If your microphone doesn’t seem to be working, or if you tried our microphone test and the line wasn’t moving, something might be wrong with your microphone settings.
Try Clicking the right mouse button inside the “Recording” tab (Follow steps 1-4 if you forgot how to get there) and checking if the words “Show Disabled Devices” have a V next to them. If they don’t, click on them to make that V appear.
This might add extra devices to the list. Perform steps 5-13 on those devices too, until you see the green bars when talking into the mic.
