Note that the microphone is not listed individually in Device Manager because it works through your sound card. Perform the steps in the following sections in order, and then test to determine if your issue is resolved after each section.

NOTE: The microphone should be selected as the recording device in the Volume Control tool(sndvol32.exe).

To verify this, follow these steps:
Click Start, and then click Run.

  1. In the Open box, type sndvol32.exe, and then click OK.
  2. Click Properties on the Options menu.
  3. In the Adjust volume for box, click Recording.
  4. Click OK.
  5. In the Microphone box, verify that the Select check box is selected.
All the properties listed on the Playback section of the Volume control are independet of the recording settings. So you could record through the microphone by selecting it on the recording section, and mute it on the playback section. Then, you could record sound, but wouldn't hear it through the speakers while you are recording. Check Your HardwareIf your microphone has never worked, or if it has stopped working, first check the physical connection of the microphone. Verify that it is firmly plugged into the microphone port instead of the headphone or speaker port. If you are not sure which port is correct, you can check the sound card to see if it is marked (sometimes with a picture of a microphone), you can use a process of elimination, check the documentation that came with your hardware, or contact the hardware manufacturer. Sound Recorder
  1. Run the Sound Recorder tool: Windows 95Click Start, point to Programs, point to Accessories, point to Multimedia, and then click Sound Recorder. Windows 98Click Start, point to Programs, point to Accessories, point to Entertainment, and then click Sound Recorder.
  2. After Sound Recorder is running, click Record (the circle on the right side), and then speak into the microphone. If it is plugged into the correct jack, the line on the display should move up and down. If it does not move, sound is not making it through your microphone. If the line does move, press Stop, press Rewind, and then press Play to listen to your recording. If this works, but it does not work in your program, view the "Using the Microphone in Programs" section in this article.
  3. Still Cannot Record
If you cannot record a .wav file after you follow the steps in the previous section, there may be a problem with your microphone property settings. To check these settings:
  1. Double-click the Speaker icon on the taskbar, and then verify that the Microphone slider is at the top and that the Mute check box is not selected. If Mute is selected, click to clear the check box.
  2. Select Properties from the Options Menu. Select Recording and click OK. Verify that theSelected check box under Microphone is checked, and that the Microphone slider is at the top.
  3. Try recording a .wav file again.

The mic on your phone is not working... check if it is muted on your phone...

If it is not muted, then it can be a hardware issue, your mic might have gone bad... you can take it to any service center and get the work done there....Just ask them to replace the mic, the cost of the mic is very cheap it costs around less than half a dollar in INDIA....
