[5 Ways] How to Fix Sound Constantly Changing Windows 11/10?

Have you ever encountered a situation that your computer volume changes by itself without your operation? For example, while you are working on your business like watching a movie, the sound of the speaker increases or decreases automatically but you have done nothing.

Below is a user asking for help on answers.microsoft.com:

Whenever I try to change my volume, Windows automatically changes it back pretty much instantly. Besides that, it’s constantly changing my volume levels seemingly to keep the output the same. It seems to be a setting related to either the maximum volume or to keep the output volume the same. Moreover, this is happening on every device I connect to it. Whether it’s a regular sound system or headphones (2 different ones), it’s doing it to every device.

That seems ridiculous and maybe horrible for someone, but it does happen to some Windows users and it is just one of the many bugs/errors that Microsoft throws to its users. Luckily, many victims have successfully solved the problem by relying on one of the following methods.

3. On the Other troubleshooters screen, click on the Run button for Playing Audio.
4. Then, follow the on-screen guide to complete the process.

#2 Disable Sound Enhancements

Both Microsoft and 3rd-party vendors provide audio enhancements that are aimed to make specific hardware sound better. Yet, sometimes, those enhancements can result in sound problems like the mentioned auto volume change. For such a situation, you may need to disable or remove those enhancements to deal with the error.

#3 Update/Roll Backup/Reinstall Audio Driver
