In order to hook up a laptop to a TV, most HD TVs nowadays use HDMI cables as their standard inputs, offering both a crisp graphic quality and a high quality sound. If you’re having sound issues with your HDMI set up, there are a couple of standard troubleshooting actions that you can take to make sure it isn’t anything minute.
Check the Sound Mixer
You’ll want to make sure that your sound outputs for your laptop and your TV are functioning correctly. Verify that nothing is muted and that you’ve selected the correct sound output (the TV speakers). Set the HDMI connection as the default output device.
Check the HDMI Cable
It’s possible that you may have a faulty HDMI cable. Since HDMI cables carry a digital signal, there usually won’t be a loss of sound quality if your video is working, unless you actually have a damaged cable. Make sure that the HDMI connection is secure on both ends and that the sound input is same as the video input for your TV. The TV should also be configured to view via HDMI ,which is usually done through the TV set-up menu.
Some HDTVs also require that the computer is connected specifically to a PC HDMI port, rather than a standard HDMI port. Check your TV for a PC HDMI input, and connect if possible. You may also want to switch between a couple of HDMI ports to make sure that the input is working.
If none of the above steps solved your problem, you most likely have a problem with your graphics card or a problem with your input or output ports on your computer. In this case, it’s highly recommended that you talk with a computer repair professional to discuss how to repair your HDMI connection.
