Fixing the Notorious 0XC00D36B4 Windows Sound Issue

If you’re a Windows user who loves to listen to music or watch videos on the computer, encountering an audio error can be a real annoyance. One such error is the 0xc00d36b4 error, which is often caused by an incompatible file format or missing codecs.

In this guide, we’ll explain the common causes of this issue and provide you with some effective troubleshooting methods to help you fix it.

Understanding the Problem Behind Audio Error 0xc00d36b4 on Windows

The audio error 0xc00d36b4 occurs when Windows fails to play audio due to a problem with the audio codec. It typically occurs on the Groove Music or the Movies & TV app, and can be caused due to one or more of the following factors:

• Incompatible audio codecs - the codec required to play the targeted file might be missing or incompatible with your system, preventing the app from functioning properly.
• Corrupted media files - the file itself might be dealing with a corruption error or may not have been downloaded correctly, leading to the audio error. In some cases, the file simply may not be supported by the media player you are trying to use.
• Third-party codecs - Nero codes, if installed in the system are known to interfere with the process of Groove Music or the Windows Media Player.
• Outdated or corrupted audio drivers - the essential drivers required to play audio files in Windows might be outdated or infected with an error, which is preventing them from connecting with the audio hardware properly and causing the error.

Below, we have listed different troubleshooting methods that can help you fix the problem in no time, regardless of the cause. Choose the solution that is most appropriate for your situation.

1. Check the File Format of the File You’re Playing

Different media players and codecs support different file formats, and if the file you are trying to play is in an unsupported format, the player will fail to play it, leading to the problem at hand.

This is why, the first thing that we recommend doing is making sure that the file you are trying to play is in a supported format. You can do so by right-clicking on the file and choosingProperties . Head over to theGeneral tab and check the file extension or file type there.

If it is not, you can use a third-party application to convert it into a compatible format. Alternatively, you can try using another application that supports the format of your audio file.

2. Run the Audio Troubleshooter

Another easy way of fixing audio-related issues in Windows is by running the audio troubleshooter.

It works by checking your audio settings and hardware for potential issues. If any problems are identified, the troubleshooter will suggest fixes that you can apply by using theApply this fix button in the utility.

Here is how you can do that:

4. Uninstall Nero Codecs

As we mentioned above, if you have Nero Codecs installed on your computer, then there is a chance that it is interfering with the processes of Groove Music or the Windows Media Player.

If this applies to you, the easiest way to resolve the issue is by uninstalling Nero Codecs. Here is how you can do that:

1. Press theWin + R keys together to open Run.

5. Disable Copy Protection

In some cases, users noticed that the copy protection feature was preventing certain files from being played. This feature is typically used to prevent unauthorized copying and distribution of copyrighted content but can also cause conflicts with the relevant hardware and software.

By disabling it, you can bypass any restrictions this feature may have implemented that are causing the issue.

Here is how you can do that:

1. Open the Windows Media Player and click on theOrganize button in the top-left.
2. ChooseOptions from the context menu.

6. Update Audio Drivers

There can be a problem with the audio drivers installed on the system, which is preventing them from communicating with the relevant hardware and leading to the problem.

This typically happens when the drivers are either corrupt or outdated. Fortunately, both of these issues can be fixed byupdating the audio drivers on Windows . The easiest way of doing this is by using the Device Manager utility that comes with Windows by default.

7. Reinstall Windows Media Player

Finally, you can try reinstalling the Windows Media Player which will clear out any issues within the media player itself that may be contributing to the issue.

Alternatively, you can also consider switching to a third-party media player that offers a similar functionality until Microsoft releases an official fix for this issue.
