If Bluetooth Speaker Volume Control not working and you cannot adjust the volume of a Bluetooth speaker in Windows 11/10, do this to fix the issue.

Do you find the floating volume rectangle annoying? You can remove Volume OSD floating in Windows 10 or replace it with Windows 11 OSD.

Windows 11 has a new volume mixer, which can be accessed with a keyboard shortcut. The volume mixer allows you to set a custom volume level for each app.
