In recent years, the TV has long ceased to fulfill its direct appointment. To date, new models of these devices are also monitors, but with a significantly greater diagonal, rather than the models that are made specifically for computers. For this reason, these days, very often computers, tablets and other techniques are connected via the HDMI connector and the corresponding cable to the TV, which allows the image and sound to it. But it happens that the sound is either at all when connected, or it disappears with time. We will try to figure out why it happens and how to fix it.
First, try to figure out why sound disappeared or why it is simply not transmitted through the cord of the specified type. So, the first reason why the sound does not go to the TV, it can be hidden in that On the TV, a silent mode is activated using the MUTE key. Or the volume level can be installed on the minimum. Often the problem is solved just very simple. by the way, will not be superfluous to see how many HDMI ports has a TV.
If it is not alone, you can connect the wire to another connector of this type.
Another reason is the sound of a sound to a completely different device. This problem is characteristic of computers that run under the Windows operating system. So, this operating system has one property – when you make changes to some settings, installing updates, connecting equipment and other actions, the device may be incorrectly selected to which sound is carried out. That is, if the computer has several devices that can play sound, then the operating system can choose exactly the device that needs to be. That is, it may turn out that there is a sound in the PC columns, but it’s impossible to withdraw it to the TV.
The third common problem, due to which the TV does not reproduce the sound when connecting the HDMI type, is The most common absence of the required video card driver. More precisely, we are talking about the component that is responsible for the output of the sound on the HDMI connector. Or it can be installed, but not updated to the new version, because of which it works incorrect. It often happens even so that it seems to be a user and installed the desired driver, but I did not put the checkbox when installing it on the desired component, because of which the driver was mounted simply without it.
Another fairly often arising problem is that Simpar need to configure the sound in the control center directly by the driver, which is responsible for the output of the sound on the TV. The fact is that often the drivers of this type contain their own management centers where various settings are present using the connected audio and video engineering.
Well, it happens so that Users simply confuse HDMI interface with any other and connect via VGA or DVI. These cable types do not allow the transmission of sound to the TV, which easily explains what it does not reproduce it. Or the connection can be carried out via HDMI, but using adapters of the specified standards that sound also do not transmit. It happens that the cable is simply not determined. The reason that it does not work, most likely will be Physical damage.
Check volume levels on TV and computer
Now try to figure out how to check the levels and set up the desired volume levels or turn on the sound at all if it is turned off. First do it on the computer. To do this, open the volume panel with the volume levels. This can be done if you click on the loudspeaker sign, which is located on the left of the date and time in the right-hand side of the taskbar. If the sound is at a minimum, it is necessary to increase the volume with the slider to a comfortable level.
Now you should clap the sound icon right-click and select “Mixer Volume”.
A new window will appear, where you can enable the required volume level for the TV and the working program. If you are not using a personal computer, but a laptop, then you can increase the volume and hardware. To do this, it is required to clamp the Fn key with one of the keyboard buttons on which the loudspeaker icon is depicted. Different producers they are different. In the left side of the display, a window opens with a level that can be switched above by pressing the specified key combination.
Besides, You should check the sound on the TV. To do this, you can enable some channel and click on the volume button on the console. You should make sure that some silent mode is not included on the TV. If the audio stream is present, the device is properly. If not, you should contact the repair master. If for some reason no reasons are not at hand, you can use the volume button on the back or front panel of the TV depending on the model.
Select the correct playback device
As described above, it happens that The reason for the lack of sound when the computer is hdmi-connected to the TV is the wrong selection of the playback source computer. As already mentioned, the Windows operating system determines the playback device yourself after connecting. And the automatic choice is not always true, because of which it has to reconfigure manually. To select the correct playback device manually, you need to make the following actions:
- To quickly call the “Reproducing Devices” window, you should drive the mouse to the volume icon and click on it right-click – you can see a few items, you should find “Playing devices” by clicking on the left mouse button;
- Now you should find the item with the title of the TV;
- You need to click on the “Use By Default” button;
- We are waiting for “apply” to save your choice.
If you do not see the item with the name of the TV, then you should click on an empty place right key, where you need to find the item “Show disabled devices”. If there is a TV among them, then it needs to be found and perform the above steps. Note that This setup algorithm is suitable for both Windows 7 and 8, and 10.
Installation of drivers
As mentioned above, the problems with the drivers can be another cause of the problem that is considered in this article. To begin, it should be understood how to establish the fact that the problem is in the drivers.
The problems with them will be evidenced by exclamation and question marks next to device icons in device manager.
If there is a question mark, then this means that the driver is not installed at all, and if exclamation – it means that there is a driver, but it works incorrect. For example, it may be damaged by viruses. In addition, an exclamation mark may indicate the need to update the driver. In any case, when problems with drivers, go to their installation. We will try to consider how to do it on Windows 7 and Windows 10.
For Windows 7
So, if you need to download and install drivers on Windows 7, then The following actions should be done:
- To begin with, go to the official website of the video card manufacturer;
- After that, in the appropriate forms, select the type, series and device family in the appropriate menu;
- Now in the new window you will need to specify which the operating system is standing on the computer, as well as in which language must be installer;
- After that, a link to the newest package of drivers for your video card will appear on the site to be downloaded by clicking on the appropriate key on the screen;
- After the driver is loaded, you need to enter the “Download” folder where the installer will be started;
- Now you should select the desired drivers components that you want to install, and then click on the corresponding button, you will need to check the box next to the HD audio producer item, because it is responsible for the transmission of sound on HDMI;
- Now it remains to wait until the installation is completed;
- Reboot a personal computer and see if the problem was solved.
For Windows 10
In Windows 10, the installation algorithm will be almost identical, with the exception of several points, due to which it is no longer able to repeat it. But here you need to note a number of nuances that can confuse the user. The first is that the automatic loading or installation of the most appropriate drivers immediately after the computer will connect to the Internet after installation, is implemented in Windows 10. Because of this, the problem often happens at which the system does not show any problems with the driver, but it is not fully installed. That is, the driver itself will be installed, but the manufacturer’s interface – no.
Because of this competent management of the driver or its settings, it is impossible to produce.
Another aspect concerns what often happens that when requesting the system to update the drivers, it will argue that the installed driver is the last. But you can go to the site of the official manufacturer and make sure that it is not. So We advise you to download the drivers only from the manufacturer’s official website and periodically check it on your own on the subject of new versions of the drivers.
What to do if nothing helps?
Suppose that all of the above actions did not bring the proper result, and still when the computer is connected or a laptop via HDMI cable there is no sound on the TV. To begin with, take another HDMI cable and try to connect devices to them. The problem of this type of cables is often lies in the fact that There is a physical damage in some place, but due to the fact that the wire is hidden by the layer of protection, it is impossible to diagnose on the eye.
You can still try to connect another computer to the TV. If everything works, it means that the problem is in the computer – and it will be possible to look for the problem exactly on this device. Another option of how can act, is that if you use some adapters, then one of them can simply be faulty. In such things it is not recommended to use adapters generally, because they often do not support the possibility of transmitting sound in the cases in question.
If some additional software is present, which is intended to control the adapter, should be more careful to see its settings. It is possible that simply does not correctly configure the operation of the specified device. It can also be faulty either the TV itself, or its HDMI port. To do this, you can try to connect another device to it, replace the cable or connect a laptop, computer to another TV, which will allow you to determine the definition source with a high probability.
How can you make sure there is a fairly large number of cases when there is no sound on a TV when connected via HDMI cable. But at a certain desire and some skills in the field of working with a computer, it is quite possible to eliminate such a problem.
