When the sound icon in your taskbar has a red x on it (as illustrated above), your computer won’t play any sound.
This is usually caused by one of two problems: either Windows has disabled your audio device or your PC doesn’t have the latest correct device drivers installed, and Windows therefore can’t ‘talk’ to the device.
If you see No Audio Output Device is installed when you hover your mouse over the sound icon, your audio problem is probably caused by one of these issues, and there are three repair methods you can try that have helped other users. You may not need to try them all; just start at the top of the list and work your way down.
