Win7 taskbar speaker icon does not show how to solve?

View the status of the sound horn, click on the taskbar, and then select Properties

In the taskbar properties, select the Taskbar tab, click Customize in the notification area settings item

After you complete the second step, in the Notification Area icon window, click on the "Turn System icon on or off"

In the Open or Close icon window, we found that the icon for that sound was "off" and that the Pull-down menu was not available, so we can rule out the shutdown.

The second approach is to open your task Manager, find "Explorer.exe", and then end the process.

Then click on the "File" menu to create a new task, enter "Explorer.exe" again and click OK.
