I connected the monitor via hdmi cable and there was no sound.

An HDMI cable is a means of connecting digital devices, which is designed to transmit high-quality multimedia data with copy protection. Since 2002, this device has been evolving to this day, improving its throughput and adding support for new displays. Current version as of 2019: HDMI 2.1, supports all resolutions up to 10K100 inclusive. What should I do if after connecting via cable to the monitor there is no sound?

Why might there be no sound when connected to a TV?

Loss of sound when connecting an HDMI cable to a TV is a fairly common problem; it is associated more with inability to handle the equipment than with cable problems. The standard situation is this: this cable does not conduct sound when connecting a laptop or computer to the TV, but it appears on primary media.

ATTENTION: The cause of the problem in most of these cases is simply low volume on the device. The currently adjusted volume can be viewed in the computer mixer or in the TV settings. It's possible that someone accidentally turned on silent mode, since these buttons are usually located on the monitor body.

The reason may lie in the banal lack of necessary software, in other words, drivers for the required cable or TV monitor on the donor device.

REFERENCE! Also, the error may occur due to the fact that the computer is “not ready” to transmit sound, and you need to point it to a suitable device after you have connected it manually in the properties. Read below to find out how to get rid of these problems.

How to get rid of the problem

The problem of no sound when connecting an HDMI cable is not as difficult as it seems. To do this you need:

1. Set up audio output. In the southwest corner of the screen you can see a horn icon - these are the properties of sound. You need to hover the cursor over it and press the right button - a menu will appear where you should select the “Playback devices” item. A window will pop up with a list of available audio outputs. All that remains is to find the item whose text says “High Resolution Definition Audio”, or simply “HDMI”, right-click on this item and select “Use as default”, then close the menu by clicking OK.
2. Install drivers. To access the drivers window, you need to press the key combination “Windows + R” (the Windows key is a button with a flag in the lower left corner of the keyboard) and enter “devmgmt.msc” in the line that opens. A window will open where you should select the “Sound devices” list and try to find the item containing “HDMI”. If it is there, then the drivers need to be enabled by right-clicking on the desired item and selecting the appropriate solution in the menu. If this is not visible in the list, it means that for some reason the drivers for the cable were not installed, and you need to download it yourself from the website of the video card manufacturer (AMD, NVIDIA or Intel).
3. The sound may also be lost due to the use of adapters or adapters. In this situation, nothing can be done except replace the adapter and try another one.
