Hi Susanna,
Thanks for your post. Can I know if you have tried to disable the icon sound with system level? If not, please try the following method and see if it works.
Disable system icons: Right-click on your taskbar and select “Taskbar Settings.” Scroll down to the “Notification area” and select “Turn system icons on or off.” Uncheck the volume icon to hide the volume overlay.Best Regards,
Ian Xue
