Attention Before you read this tutorial, I highly recommend you check out my resources page for access to the tools and services I use to not only maintain my system but also fix all my computer errors, by clicking here!

A common problem that many users face when they attempt to upgrade their Windows operating system from Windows XP/Vista to Windows 7/8 is their microphone not working. If you are a Windows user and are facing issues with your microphone, then this article was made for you. In fact, the vast majority of the solutions outlined below should work on all versions of Windows.

When I say microphone, I’m referring to an input audio device that you connect to your system for the purpose of speaking or recording audio, whether it’s for an instant messenger application (like AOL messenger or Yahoo Messenger), Skype, webcams etc.

This refers to the following hardware components:

  • USB Headsets, Headphones or Microphones
  • USB Webcams with Internal Microphones

Common Microphone Errors

Here are some of the many audio or microphone-related error messages that users may encountered throughout the use of their system:

“Could not initialize the volume meter: Please select a different audio input device”
“Windows cannot execute DpvSetup.exe”
“Word is not receiving sound from microphone”

How to Fix It

For those of you in this unfortunate position, trying to figure out why their microphone device is not working, there are many different things that you can do, fortunately. Whether it’s a driver check, or connection issue, below are some of the many solutions that users in your current position have utilised to fix this common issue.

Update Your Audio Drivers

If there is an issue with your audio drivers, this could result in your microphone not working as well as other sound components connected to your system. Outdated or corrupted device drivers are the cause of a great many device errors.

With that said, I recommend you use Smart Driver Updater to automatically search the internet and download the most up-to-date and compatible drivers for your audio device. Smart Driver Updater is a powerful and very helpful tool, especially for the beginner to intermediate users. You can download this tool here:


Alternatively, if you have the computer capabilities and knowhow, then you can attempt to find the most up-to-date audio device drivers yourself. A good place to start is on one of the major search engines.

The solution(s) below are for ADVANCED level computer users. If you are a beginner to intermediate computer user, I highly recommend you use the automated tool(s) above!

Check the Connection

Sometimes issues like this are far less than they are made out to be. Plugging your microphone device into the wrong port on your sound card is something that is a fairly common mistaken.

For the vast majority of sound cards, the microphone connection is typically painted in pink, which is the port your microphone should be connected to.

However, there are those sound cards that do not come with colour coded ports, in situations like this; it’s recommended that you consult the manual of your sound device.

Ensuring your microphone is connected to the correct port could potentially save you on countless hours of troubleshooting.

USB Microphones

If you’re using a USB based microphone, then try connecting the device into a different USB port. If you’ve connected to your USB microphone to one of the USB ports at the back of your computer, consider using one of the USB ports at the front of your system.

If you have your Microphone connected to your computer through a USB hub, then you should consider bypassing the device, by connecting the USB microphone directly to your computer.

Test Your Microphone

If after updating the drivers for your sound device, the microphone still fails to work, then you should consider taking the microphone out of your computer and plugging it into another system.

Using this method you should be able to determine whether or not the problem is hardware related (the microphone itself), or software related (the operating system).

Check Audio Settings

Make sure you have your microphone set to default in your audio settings. In order to do this, simply do the following:

1. First, boot into your computer with full administrative rights.

2. Then click on Start -> Control Panel.

Start -> Control Panel

3. From here, double click on Sounds and Audio Devices [Windows Vista/7: Hardware and Sound].

Control Panel -> Hardware and Sound

4. Windows Vista/7: Then click on Manage Audio Devices, under Sound.

Hardware and Sound -> Manage Audio Devices

4. This will bring up the Sounds and Audio Devices Properties [Windows Vista/7: Sound] applet, from here, click on the Audio [Windows Vista/7: Recording], Tab, then under Sound recording, make sure your Microphone is set to Default device [Windows Vista/7: click on your Microphone, then click on Set Default].

Recording -> Microphone -> Set Default

Note: If you already have a microphone set to default, make sure it is the correct one. This is a common issue where a third party application such as Skype, will attempt to use the wrong device when a user tries to make a voice call.

Check the Software

If your microphones not working correctly on a specific application (such as Yahoo Messenger), but working correctly on other devices, then you’ll want to ensure that your microphone is selected in the Preference, Options or Tools menu of that specific application.

Updating an application is capable of causing conflicts and other issues within the settings menu, despite the fact that the device worked correctly, prior to the update. So double check the application settings.

Check the Mute Option

This is a common mistake that many make, though this is something you probably should have looked into, prior to seeking help. With that said, have you checked whether or not the mute button has been selected for your microphone?

Check Your Sound Card Software

Many sound card devices come with audio programs that are designed to make managing the audio device easier. In many cases, these applications will try and take over the management of your devices within Windows. A good example of this is the RealTek HD Audio Manager and the Creative Mix Console.

Consider checking the settings of these applications. If you find any settings that may be interfering with your microphone, then consider turning it off.

If you believe the software for your audio device is the cause of your problem, then I recommend you check with your sound card manufacturer for a driver-only option.

Close Conflicting Applications

There are many applications such as Skype, Yahoo Manager and others that are capable of stealing your Microphone input away while you attempt to use it, in say, a gaming environment.

Consider closing down any applications that work with your microphone, when attempting to use the device for other applications, such as a computer game, or webcam.

Poor Voice Quality

Poor voice quality is a common issue that can stem from many different computer situations. Below are some of the most common situations associated with poor microphone voice quality:


In most instances, you will receive feedback, if you have your speakers cranked up really high while attempting to use your microphone.

It’s highly recommend that you use a headset, which is an earphone/microphone hybrid, when attempting to communicate with other users, in say, a gaming environment. Some cheaper microphones are what we call omni-directional, which means they will pick up sounds from all directions, including from your speakers. So consider switching off or turning down your speakers, before attempting to use your microphone.

Low Volume

Your microphone not working may be due to the device volume not being set to the highest in the volume controls, which is a simple, yet common mistake many make. Anyway this can be rectified by doing the following:

1. First, boot into your computer with full administrative rights.

2. Then double click on the Sound Icon, in the bottom hand corner of the screen.

Click on Sound Icon

3. This will bring up the Volume Controls, from here, set the Microphone volume slider to the top.

Volume Controls -> Microphone

Note: In certain situations, the Microphone volume control may not be a visible option. In situations like this, you will have to make it visible, by clicking on Options -> Properties, then checking Microphone and clicking on OK.

Sound Distortion

In many situations, poor microphone voice quality may be the result of a faulty cable or bad connection. Make sure the connection to your PC is secure, if it is not, then there is a good chance that it may be damaged; if you experience the same situation (poor audio quality) while using your Microphone in other applications, then you may want to consider purchasing a new one.

The cheaper, less costly microphones, shun quality in order to keep prices low, so keep that in mind when purchasing a new one.

Also make sure there is a suitable distance between the microphone and your mouth, when speaking into it. If you like to position yourself so close that your lips are touching it, consider stepping back an inch or two, then speak into it. If the microphone doesn’t come with a windscreen, then you may want to try moving it even further away from your mouth.
