We have an online version of the Windows Audio Troubleshooter that we use to test out new solutions before integrating those solutions directly into the built-in Windows Audio Troubleshooter. We've done some work to integrate the list of solutions from my blog post into the online Troubleshooter, which you can run from this location: https://go.microsoft.com/?linkid=9863220.

When you run the online Troubleshooter from this link, you'll see a window like this:

Click "Next" and the Troubleshooter will then ask you to select the audio device you wish to troubleshoot:

Select the appropriate device and click "Next". You'll see a window like this:

This isn't very descriptive. "Emerging issue 69319" is actually a rather esoteric name for the new set of solutions (from my blog post) that we are testing with the online Troubleshooter. Click "Next".

From this point, the windows you see will depend on the problems detected by the Troubleshooter. Follow the prompts and let the Troubleshooter do its work.

Keep in mind that these new solutions are still in test, so while they work most of the time, they still can fail in some circumstances. Once we work out all the issues we'll integrate these fixes into the version of the Audio Troubleshooter that's built into Windows.  

This document is designed to help you resolve any audio issues you may be having, and, failing that, help you collect information we can use to successfully diagnose and fix your problem.

My Audio Doesn’t Work at all!

In this scenario, no audio works on your machine. You can’t play music, hear system sounds, or play any audio from the internet. Let’s see if we can’t get this fixed. Please try the following:

1. If your computer is recent (shipped with Windows 8.1), check the manufacturer’s web site for updated drivers

2. Check for driver updates from Windows Update

3. If your device is external, like headphones or a USB device, unplug and plug-in the device

4. If your device is USB, try a different port

5. Try disabling audio enhancements, if applicable

6. Check to see if using a different default audio format fixes your issue

7. Uninstall your audio driver and reboot to let Windows reinstall it

8. Uninstall your audio driver and try using the inbox driver (HDAudio)

  My Audio Sounds Bad!

In this scenario, you can play audio as expected. Music, video, and system sounds play just fine; however, they sound garbled, clipped, tinny, or just generally bad. Let’s see if we can’t get this fixed. Please try the following:

1. Check for driver updates from Windows Update

2. If your device is external, like headphones or a USB device, unplug and plug-in the device

3. If your device is USB, try a different port

4. Try disabling audio enhancements, if applicable

5. Uninstall your driver and reboot to allow Windows to reinstall it

6. If that doesn’t work, uninstall your audio driver and try using the inbox driver (HDAudio)

 My Headphones/Speakers/Bluetooth won’t Play/Switch!

In this scenario you can play audio through one or more endpoints (speakers/headphones/Bluetooth device, etc.), but you can’t get audio to play through another endpoint you believe should work. For example, you are able to play music over your built-in laptop speakers, but when you plugs in your wired headphones, audio continues to play over the speakers (or no audio plays at all).

1. Check for driver updates from Windows Update

2. If your device is external, like headphones or a USB device, unplug and plug-in the device

3. If your device is USB, try a different port

4. Uninstall your driver and reboot to allow Windows to reinstall it

5. If that doesn’t work, uninstall your audio driver and try using the inbox driver (HDAudio)

 My microphone doesn’t work!

In this scenario can’t get your microphone to work, and you’ve probably discovered this because Cortana can’t hear you. You may find that plugging an external microphone into the computer or using a headset works better.

1. Check for driver updates from Windows Update

2. If your device is external, like headphones or a USB device, unplug and plug-in the device

3. If your device is USB, try a different port

4. Try disabling audio enhancements, if applicable

5. Uninstall your driver and reboot to allow Windows to reinstall it

6. If that doesn’t work, uninstall your audio driver and try using the inbox driver (HDAudio)

 If none of these suggestions worked:

1. Visit the Microsoft Community at https://answers.microsoft.com and see if anyone else is reporting a similar problem. If so, join the conversation and provide the following information:

   1. Let us know the make and model of your PC

   2. Also tell us the hardware ID and driver version of your audio device

   3. Try to play a Test Tone and let us know if it worked

   4. Capture a screenshot of your “Sound, video, and game controller” tab in Device Manager

   5. Check to see if your device is trying to play audio by noting whether green volume bars are present in the Sound Control Panel

2. If you’re the first to report a new problem, feel free to start a new conversation and provide the information listed above.

 You asked me to do something… But I don’t know how to do it!

Finding the Device ID and driver version of your audio hardware

1. Run Device Manager

2. Go to Sound, video and game controllers

3. Double-click your audio device

4. Go to the Details tab

5. Select Hardware IDs

6. Right-click to copy the IDs and then paste them in your reply

7. Select Driver version, right click to copy and then paste the version in your reply

Uninstalling your audio driver

 First we need to identify your default device driver. Go to the Sound Control Panel via one of the following ways:

1. Navigate to the Control Panel, and click the “Sound” link

2. Run “mmsys.cpl” in your search box or command prompt

3. Right-click on the sound icon in your system tray and select “Playback Devices”

4. In the Sound Control Panel, note which device is your system default

5. Return to your desktop.

6. Type “Device Manager” in your search box and click on the Device Manager app

7. Expand the “Sound, video, and game controllers” tab

8. Right click your default audio device driver, and click uninstall

Checking for driver updates from Windows Update

Windows Update is a utility that keeps your PC safe and your hardware drivers freshly updated.

1. Type “Windows Update” in your search box and click on “Check for updates”

2. In the Update & Security settings page, click “Check for updates”

 Playing a Test Tone

Playing a test tone excercises the most basic system audio functionality and helps us verify whether or not your machine’s audio subsystem has any function at all.

1. Go to the Sound Control Panel via one of the following ways:

2. Navigate to the Control Panel, and click the “Sound” link

3. Run “mmsys.cpl” in your search box or command prompt

4. Right-click on the sound icon in your system tray and select “Playback Devices”

5. In the resulting window, right-click on you “Default Device” and select “Test”. You should hear test sounds playing out of your default audio device. Make sure your volume isn’t too low or muted!

Are Green Bars Visible?

Even if you can’t hear any audio, the audio subsystem may still be trying to play sounds successfully. One way to test this is by checking whether or not the system *thinks* it is playing audio. We can test this by seeing whether the volume level meter on your playback device is active.

1. Go to the Sound Control Panel via one of the following ways:

2. Navigate to the Control Panel, and click the “Sound” link

3. Run “mmsys.cpl” in your search box or command prompt

4. Right-click on the sound icon in your system tray and select “Playback Devices”

5. Play some audio, and look at your “Default Device”. Do you see green volume bars?

 Disabling/Enabling Audio Enhancements

With Windows, both Microsoft and 3^rd party vendors ship audio enhancement packages designed to make your system’s specific hardware sound absolutely perfect. Unfortunately, sometimes things go wrong. To rule out an enhancements issue, please perform the following:

1. Go to the Sound Control Panel via one of the following ways:

2. Navigate to the Control Panel, and click the “Sound” link

3. Run “mmsys.cpl” in your search box or command prompt

4. Right-click on the sound icon in your system tray and select “Playback Devices”

5. Right-click your “Default Device” and click “Properties”

6. Check the “Enhancements Tab”. If you check “Disable all sound effects” does your issue resolve? (If you don’t have an Enhancements tab, don’t worry, this isn’t the problem in that case).

7. Exit the properties window. In the Sound Control Panel, go to the Recording tab, and repeat from step 3 after right-clicking your Recording “Default Device”.

 Trying Different Audio Formats

Windows audio devices support a wide range of audio formats. Sometimes, incompatibilities with drivers or the audio software in Windows affect audio playback or recording. In this section, we rule out or confirm audio format issues as the source of your issue.

1. Go to the Sound Control Panel via one of the following ways:

2. Navigate to the Control Panel, and click the “Sound” link

3. Run “mmsys.cpl” in your search box or command prompt

4. Right-click on the sound icon in your system tray and select “Playback Devices”

5. Right-click your “Default Device” and click “Properties”

6. Go to the “Advanced” tab

7. Try changing your Default Format a few times. Does your problem resolve with any other format?

 Checking Device Manager

Device Manager is a utility that collects and displays information about the driver profile for all the hardware devices present on your system. Here, we rule out a driver issue by checking whether any audio devices have problems already identified by the system.

1. Type “Device Manager” in your search box, and hit enter

2. Expand the “Sound, video and game controllers” tab.

 Uninstall your audio driver and use the built-in Windows Audio driver (HDAudio)

Microsoft and our hardware partners work hard to ensure audio drivers are high quality, however, sometimes things break. We ship an audio driver in-box that may work if your specific audio driver doesn't.
