There is no sound via HDMI when connecting a laptop or computer to the TV
Why is there no sound via HDMI when connecting a laptop or computer to the TV? Many users are faced with such a problem who are trying to connect a laptop or PC to the TV.
Over, this problem can appear and disappear in almost randomly. Sometimes the sound is perfectly transmitted through HDMI, and sometimes continues to play from the speakers of a laptop or computer and it is not possible to fix it.
Of course, there are many reasons that can lead to a situation where, when connecting, the sound will not be displayed through HDMI. But most often the reason is the wrong settings of the Windows operating system. In this article, we will show how to fix it in Windows 11, Windows 10 and Windows 7.
How to fix the absence of HDMI sound in Windows 10 when connecting to the TV
There are many reasons causing HDMI problem there is no sound in Windows 10 when connecting to the TV.
It all starts with the HDMI cable, which you use to connect to a computer, TV or monitor. Connect the HDMI cable to another PC/TV and check if you hear the sound. If so, then the problem with the monitor or the TV you project. You will need to configure it to receive HDMI.
If the problem with sound is not eliminated, this indicates the problem with the HDMI cable. Therefore, try to connect with a new serviceable cable.
HDMI No Sound in Windows 11 When Connect to TV No HDMI Audio Device Detected FIX 
Sound problems on PC can be caused by several reasons:
- The choice of an incorrect audioraider or an incorrect playback device.
- The sound card of the dynamics is set by default instead of switching an audio output to HDMI.
- Not tuned for quantitative assessment and receiving audio.Domed HDMI.
Before starting solving the problem of lack of sound on a TV with HDMI cable, here is a list of the main checks that you need to perform:
- Correctly connect the HDMI cable. Make sure the HDMI cable is not damaged and is not faulty.
- Make sure the video card (NVIDIA control panel) is correctly configured.
- NVIDIA cards (series to GeForce 200) do not support the sound of HDMI.
- Realtek drivers also have compatibility problems.
- Reload the devices, since simple reboot in most cases eliminates minor problems and software failures.
Below are the various methods that will help you turn on the sound transmission through HDMI to TV. Read to the end to find the one that suits you.
Not much different from HDMI. DVI Inte Wee is a modern digital connector. The problem is that this output is on many computers, but it is extremely rare on laptops. In such cases, connect the laptop to the TV using the DVI cord, you can through the adapter adapter.
When connecting a laptop to TV via a DVI cable, the user will be able to watch video content with a resolution of Full HD. 1920×1080 pixels, in fact, as in the case of HDMI. The specificity of the connection does not change depending on the manufacturer of the equipment. That is, you can calmly synchronize the ASUS laptop and Sony TV.
Some modern devices are equipped with an updated Dual Link DVI-I digital integer, which differs from a standard connector with an increased screen resolution-2560×1600 pixels.
Despite the fact that this is a digital signal, the sound will still have to be connected separately.
How to disable sound transmission through an HDMI-integse
There are situations when you need to connect an external display of information to a laptop or PC, and simply put it to connect it with a large TV or projector (if you, for example, want to arrange a small home theater at home), and at the same time use the external speaker system to withdraw the sound.
There are situations when an external device for displaying information must be connected to a laptop or PC, and simply put, connect it with a large TV or projector (if you, for example, want to arrange a small home theater at home), and at the same time, use an external acoustic derivative system.
A few years ago, mainly to output the picture from a PC or laptop, the D-Sub-Sube has already been used today as a morally obsolete analog integrated. Now, an increasing number of mobile PC mobile models, as well as the graphic adapters of desktop PC, are equipped with digital HDMI intenses, through which both the video and the audio signal can be broadcast simultaneously. But many often encounter such a problem that the function of output of the sound signal is transmitted (by default) to the external sound device (projector or TV dynamics), connected by HDMI-intenses, bypassing the most popular sound board in many (or better optical spdif intensity. ), to which (as in our case) a better sound system is connected and instead of sound you get the absence of that.
If your TV has a good built.In speaker system (which is quite rare and, as a rule, only for models of the upper price range) is not critical. The same projectors have integrated “squeaks” in quality, for the most part they also leave much to be desired. And therefore, it is worth taking a number of fairly simple steps that will lead you to the desired result.
In the case of using the Windows 10 operating system (in 7 and 8 similarly), through the standard “Start” menu, we enter the parameters (settings) ”.
In the “Devices” tab, select “Related Parameters”- “Sound Parameters”.
Before us on the “Reproduction” tab there is a general list in which it is necessary to select “Digital Audio HDMI” (lower tab).
After pressing it with the right button, click on the “Properties” item.
And click “Do not use this device”, confirm. Now the signal from your sound card will be broadcast bypassing the connection of HDMI. You can assign the necessary integration in the previous menu “Preferences” in a similar way.
How to configure the connection of the laptop to the TV via HDMI
After you have connected everything, a laptop and a TV need to be configured, without this the image will not appear. First you need to click the Source button on the TV remote control and select HDMI in the list that opens. If in the list of sources on your TV there are several HDMI you just need to choose the right one (the one to which you connected the cable).
If you are lucky, then after switching the TV to the HDMI signal, an image from a laptop will appear on its screen. But, if this does not happen, you will need to dig into the laptop settings. If you have Windows 7, then you need to click on the empty mouse button on the empty space on the desktop and go to the “screen resolution”.
After that, a window with the screen settings will appear. There are several options that allow you to control how the image is displayed. In order to transfer the image to the laptop, you need to open the “screen” menu and select the “several monitors” item. After that, the image should appear on the TV screen. In addition, in the screen settings, you can change the image resolution, its orientation, and also configure the method of working. There are 4 different ways of work in total:
- “Duplicate these screens”. The image on TV completely duplicates the picture on the laptop screen.
- “Expand these screens”. The TV screen is used as a second monitor for a laptop, expanding the user’s working space. With this method of work, it becomes possible to move the windows between the TV and the device screen.
- “Display the desktop only by 1”. The image is not transmitted to TV, only the screen screen is used.
- “Display the desktop only by 2”. The image is displayed on TV, but is not displayed on the device screen.
If you use the Windows 10 operating system, then to set up monitors you need to go to the “Parameters” menu (Windows-I keys combination) and go to the “System-Screen” section. All the same settings are available here as in Windows 7, with the exception of a resolution that is selected automatically.
Also in Windows 10 you can quickly switch between the methods of connecting the monitor. To do this, click the key combination of Windows-P (Project-project) and select one of the options: “only computer screen”, “repeated”, “expand” and “only the second screen”.
In addition, external monitors settings are available in drivers from the video card. For example, if you have a video card from NVIDIA, then you can click on the mouse on the desktop and select the NVIDIA control panel.
After the opening of the NVIDIA control panel, you need to go to the “display. Change in permission” section. Here it will be possible to change the resolution and frequency of update for each of the connected screens.
In the section “display. Installation of several monitors” it will be possible to determine connected monitors, select the main monitor and change their location relative to each other.
Similar settings are available in drivers of other manufacturers (AMD, Intel). But, they are unlikely to be useful to you, since in most cases there are enough settings that are available in Windows itself.
Why the sound is not displayed and what to do
The most common reasons why sound is not played through HDMI:
- The dynamics of the TV are faulty or the “without sound” mode on TV itself is not turned on.
- The HDMI port is faulty.
- HDMI cable is faulty.
- Bad connection: the cable is not completely inserted into the appropriate port on the PC or on the TV.
- The video card does not support sound output through HDMI.
- The wrong port is used to connect on the TV.
The first thing you need to check whether the sound volume is correct both on the computer itself and on the connected TV.
In some TV models, after connecting HDMI, the volume is automatically set to a level of 5. 10%. This protects the speakers from possible damage, and also prevents the user’s fright from excessively loud sound.
No sound on tv from pc hdmi. How to solve
The speakers of the TV are faulty
To check, it is enough to connect a third.Party speaker system to TV. Most TVs have a 3.5 mm or RCA port for this.
If the external speakers work regularly, and the sound through the integrated is not played, although all the settings are given correctly, then this clearly indicates a breakdown of integrated acoustics. In such cases, it is recommended to contact the authorized service center of the manufacturer TV.
The HDMI port is faulty
To check the operation of the port, it is enough to connect to TV another image output device (for example, a game console or a TV setup). If the sound is not displayed in this case, then the problem is clearly in the HDMI port itself.
Most modern TVs provide 2 to 3 ports for connecting a video signal source. Sometimes just helps connect to another.
It will not be possible to fix the work of HDMI yourself, so you will also need to contact the authorized service center.
HDMI cable is faulty
If mechanical damage, bends, rupture of the outer braid are noticeable on the cable, then it is recommended to replace it.
Use a damaged cable. It is not recommended. In the event that his contacts are closed to each other, this can lead to the failure of both a video card in a computer and a built.In graphic processor in the TV itself. And this is one of the most expensive breakdowns.
Especially often those who use the old HDMI revision faced this.
Such cables do not provide for the presence of golden spraying on the contacts, which is why oxides formed over time. And the connection occurs incorrectly. Therefore, it is necessary to check whether the cable is tightly inserted into the appropriate port, and also whether there are traces of the oxidation of contacts (most often have a gray or green shade).
By the way, you can get rid of oxides yourself. This requires only a toothbrush and ethyl alcohol. It is enough to carefully clean the port, let the alcohol dry, and then try to connect HDMI again.
How to find out if sounding is supported through an HDMI cable in a particular computer or laptop? To obtain detailed specifications, you must contact the manufacturer of the device.
The wrong port is used to connect on the TV
If TV has several HDMI ports, then one of them can be designated as HDMI DVI. This means that it can only be used to receive a video signal.
Why is it necessary? For those cases when the user wants to connect TV as an external monitor, but display the sound through an acoustic system connected to a computer.
If the audio must be brought to the TV, then the port of HDMI in.
Also, the user can find a port of HDMI OUT. It is used to display the image. That is, it will also be possible to connect an external monitor or TV to duplicate the video on the screen on the screen. This is mainly used by shops to combine all displays and display the same picture for a visual comparison of the image quality.
Total, connecting a computer and TV through an HDMI is quite simple. Difficulties can occur only due to the choice of the correct device for output of audio in Windows settings. But in Windows 10, this is automatically performed in 99% of cases. That is, the sound is played on the TV immediately after it is connected by a cable.
How to turn on the sound on Windows 7
In the cases under consideration, all settings must be done through PC. It is the computer that must determine the external playback device, in our case, TV. About how to correctly connect the HDMI cable from a computer to TV, read here.
In theory, if a suitable cord is used, this should happen in automatic mode. However, this does not always happen. To enable the audio signal, you need to set it up manually. How to do it:
- Click the right mouse button according to the dynamics image in the system tray;
- Select the option “Play devices”;
- Select your TV in the list;
- Click on it PKM and install “use by default”.
Opposite the TV icon, a green dynamics icon should appear. If you did everything right, but the speakers of the TV do not work, check if they are disconnected at all in the settings and whether the volume level is reduced to a minimum.
If TV is absent in the list, install the box “show the disabled devices”. If the TV appears with the status of “disconnected”, click on it PKM and select the “enable” option. After that, appoint it by default device.
Problems with drivers: outdated, damaged, disappeared
The problem may be in the drivers of the video card. There is a chance that the files are damaged or there are no at all.
Diagnosis of malfunctions with “firewood” in the dispatcher
Questioning and exclamation signs on the icons of devices in the dispatcher are talking about malfunctions with drivers. The first sign means that the driver has not been established at all, and the second is that something is wrong with him (perhaps damage, for example, after the activities of viruses on PC). The second sign may also say that the driver needs to update. In any of these cases, proceed to the installation of new drivers.
The exclamation mark may indicate that the driver lacks updates
Installation of a fresh version of drivers over the old
Often, users when installing “firewood” of the video card disconnect the installation of additional components. Among them there may be a item responsible for playing sound by HDMI. In this case, you need to load and install on the new “firewood”. How to do this for the NVIDIA video card:
Go to the official website of the manufacturer. Select the type, series and family of the product in the menu. Indicate also what kind of “operating system” you have and what kind of installer you need. Click on “Search”.
Download a package of drivers for a video card on its official website
The site can determine your video card model for you
Highlight the “HD audio.Oreer” item and run the installation
If you find that the sound with PC is not played on TV, first check the volume and sound settings on two devices. On PC and TV, there should be a default TV dynamics, otherwise the sound will go from the computer. If there are no TV speakers in PC settings, reboot the computer with an inserted HDMI cable. It did not help. Solve the problem with the controller and adapter of High Definition Audio or with the video card drivers. Perhaps the system does not have enough component “HD audio.Oreer”, which is responsible for the transmission of sound by HDMI.
Check the TV settings
Often everything turns out to be very simple. It is enough to go to the gadget settings menu and see what video input the current broadcast of the image is carried out. Typically, modern devices have several HDMI ports: 1, 2, 3. You need to choose the one in which the cable is inserted.
Here are a few more possible options for no sound when connecting via HDMI:
- The volume is reduced to the minimum,
- The Mute key is pressed on the remote control (usually the corresponding inscription is displayed on the screen).
- The device is connected to the headphone connector. In this case, the speakers will not work.
Checked all points from the list? So, the problem is definitely not on the TV. Go to the next method.
