In some environments running Windows 11, there seems to be an issue where the volume changes while playing games, videos, or certain apps.

How to fix volume changes automatically in Windows 11
Disabling Exclusive Mode
Windows 11 has a feature called "Exclusive Mode" that is enabled by default.
If this function is enabled, the volume may change automatically when you run some applications (such as games).
The "Exclusive Mode" feature is designed to improve sound quality, but it can also change the volume without permission, which can be very annoying for some users.
1. Right-click the volume icon in the bottom right corner of the screen > Click "Sound settings."
2. Scroll down the menu on the right and click "Advanced sound settings" to open it.
3. Double-click the speaker to open it.
*If multiple devices are displayed, open the device with a green check mark.
4. The Speaker Properties window will open, so click the "Advanced" tab.
5.Under "Exclusive Mode", uncheck "Allow applications to take exclusive control of this device" and click OK.
Once you have finished the setup, close any open windows and try playing a video or other content to see if the problem has been resolved.

If the volume changes when you open a specific app (Updated November 14, 2022)
Some manufacturers' computers come with a settings app installed by default, and some of the settings in that app change the volume by syncing with other apps.
For example, one example is Armoury Crate, a utility software that can manage gaming PCs from the manufacturer ASUS. It seems that system settings for each app can be configured using a setting item called "Scenario Profile," and it seems that the problematic app may sometimes be registered in this setting.
