There seems to be a chronic problem in Microsoft Windows 10 where the sound speaker icon disappears from the systray and notification area of the taskbar. Follow these steps to try to bring it back.
Method 1 – Check Settings
- Right-click the time in the lower-right corner of the screen, then choose “Properties“.
- Ensure the “Volume” icon is set to “On“.
If the “Off” setting for “Volume” is grayed out, proceed to Method 2.
Now see if the speaker icon has returned.
