Many people connect their Windows 10 computer or laptop with an HDMI cable for various purposes. Since HDMI supports uncompressed streaming media, so you can view clear images and hear clear audio. People use this to present information on the big screen so the whole audience can see it, but more often people use an HDMI cable and their computer or laptop to watch their favorite TV show or movie on the big screen at home.

This is usually used by owners of TVs without a Smart TV function. In general, people who use an HDMI cable in this way are more likely to encounter some technical problems. One of the problems you may encounter when you connect your laptop to the TV with an HDMI cable is the lack of sound on the TV. That is, the sound is played on the laptop or computer speakers, but not on the TV. It can also happen that there is no audio on the computer or laptop as well. Despite this, there are several ways to solve this situation.

Using this method of viewing video content is popular with a large number of people. It’s so popular because the HDMI cable allows you to turn an ordinary TV into a Smart TV.

Most often, people who have difficulty connecting the PC using a cable HDMI get into a situation where there is no sound in Windows. You need to extensively understand the situation and how to fix the problem with sound in Windows. However, most often it happens that the laptop or computer works and the sound plays, but as soon as you connect the HDMI cable, the illustration repeats on the TV, and there is no sound at all.

However, the most basic and simple thing you should do in the beginning is to check your HDMI cable. Maybe the problem is in it and all you need to do is replace it rather than adjust your PC.

Once you have checked the HDMI cable and made sure that there are absolutely no problems with it you need to look into the settings of your computer or laptop.
