Are you blocked by the "Failed to play test tone" error message while you are testing your speaker or headphones? This error message may appear when there's a problem between the sound device you're using and the Windows OS. Most often, you would encountered it when you're struggling with the no sound problem and you want to check if your sound device is working.
The "Failed to play test tone" error could be caused by many factors such as incorrect sound configuration, corrupted Windows files, and corrupted or outdated audio driver. If you receive the "Failed to play test tone" error message, don't trouble yourself about it. Here are several possible solutions to help you get rid of the error. Read on to try them one by one until you troubleshoot it.
The first possible solution to the "Failed to play test tone" error is to restart the Windows Audio service. It's the easiest way. You just need to:

Step 2. Type "services.msc" into the box and hit Enter to run it.
Step 3. Scroll down to locate the Windows Audio service. Right click on it and select Restart from the pop-up menu.
Then the operating system will restart the Windows Audio service. And you can check if the "Failed to play test tone" error message is gone.
If method 1 doesn't work, the next method you can try is to disable all audio enhancements. Do as follows.
Step 1. Right click on the sound icon in the notification area on the taskbar and select Playback devices.
Step 2. In the "Playback" tab, select Speakers and click on Properties.
Step 3. Get to the Enhancements tab. Check "Disable all enhancements", and then click on Apply and OK to save the change.
