Connected PC with HDMI Cable to TV but No Sound | Solution
You connected your desktop PC or laptop with a HDMI cable to your TV, but there is NO sound coming out of your TV speakers while playing a movie or video.
This problem has probably something to do with the sound settings in Windows and on this page I will show you in a few simple steps how to change these settings and solve the problem in Windows Vista, 7, 8, 8.1 and 10.
1 Open the Windows "Control Panel" on your computer.
2 Open "Hardware and Sound".
3 Open "Sound".
It will be easier to create a shortcut to the sound settings on your desktop, so that you can easily open these settings from your desktop because you need to set the settings back to default when you disconnect from your tv.
To create a shortcut: Right-click on "Sound" and choose "Create shortcut".
4 Right-click on HDMI, Digital Audio or High Definition Audio Device and choose "Set as Default Device".
When you want the sound back on your computer or laptop speakers you need to set "Speakers" as default device.
5 Click on "OK" to close the settings window.
Remember these steps because you need to set the speakers back as default after disconnecting.
