Microphone input not recognized under Windows 7

Hi NotNormal,

Welcome to Microsoft answers community forum!

Step 1: Using Windows Sound Recorder to test the microphone.

You can use this section to find out if the computer can record a signal from the

Microphone and play it back. Use Windows sound recorder to create an audio file using the following steps:

1. Plug the microphone into the computer.

2. Click Start, All Programs, Accessories, and select Sound Recorder.

3. Click Start recording and speak into the microphone.

When finished recording, click Stop Recording.

A save screen automatically opens.

Type a filename and click Save. A file of type WAV or WMA is created in the Documents folder.

If you can record the Audio using Microphone using the above method then the Microphone is working fine.
Now it should work any application that Supports Microphone. If the computer does not record audio using the above method then it could be an issue with the settings of the Microphone. Now verify the following settings.

Step 2: Enabling the Microphone.

1. Plug the microphone into the computer.

2. Click Start, All Programs, Accessories, and select Sound Recorder.

3. Click Start Recording and speak into the microphone.

4. Recording tab showing a detected signal for the Microphone device

Note: Microphone Icon should have Green check mark on it. If there is no Green check mark, it means it is disabled. If there is No green mark on Microphone it never works. To enable the Microphone Right click on Microphone and click on Enable. If you do not see the Microphone in the list, Right click on the White space and select Show disabled devices. Then you would see the Microphone. However, if you do not see the green check mark on it, Right click on it and click on Enable. And also Select Microphone and click on Set Default (If Set as default button is active).

If you see the Green check mark on Microphone the Microphone definitely works.

Step 3: Increasing Microphone Sensitivity and Un-muting the Microphone.

 1. Select Microphone and click on Properties button.

 2. Adjust the slider until to 100 % of its range.

 3. If Mute is on, click the mute button to un-mute the device.

 4. If Microphone Boost is available, boost the volume.

5. Click OK to make the changes.

Now the Microphone should work.

Hope this information helped!

Thanks and regards
