Hi, good day!
The volume on-screen indicator in Windows 11 is usually caused either by Windows itself, your web browser, or audio software installed by your laptop or PC manufacturer.
Please try the recommended methods below if it helps.
For Microsoft Edge:
Please copy the following into the Microsoft Edge address bar:
Edge://flags/#hardware-media-key-handling
Set the dropdown for "Set Hardware Media Key Handling" to Disabled
For Firefox:
Please copy the following into the Firefox address bar:
about:config
In the search bar in the Config menu, copy/paste the below field:
media.hardwaremediakeys.enabled
Change the value by clicking on the icon on the right side from "true" to "false".
For Chrome:
Please copy the following into the Chrome address bar:
about://flags
Search the option "Hardware Media Key Handling" and change it to Disabled
If the issue persists, please take a screenshot of the issue and post it in your next response.
