Hdmi sound not working windows 10

 First, please make sure whether you have correctly set audio settings in your system. (Press Windows key + X to open your system settings. Click the audio icon, and check if the output device is shown correctly.

Update the Sound Driver

Your sound driver is the software that allows your computer to communicate with your computer's sound hardware. It is a small program, usually just a few megabytes, that allows you to control your sound card. Your computer will usually update the sound driver automatically, but if it doesn't, you should update it yourself. Updating the sound driver is a quick and easy process.

The Windows Update utility allows you to select what operating systems you want to receive updates for, and what you want updates to do with them. You can select whether you want to install, ignore, or schedule updates. The Windows Update utility is available in the Control Panel under the Windows Update icon. You can also access it from your Start menu, by choosing Programs

Set HDMI Device as Default Device

An HDMI device is capable of receiving audio and video content as well as setting the device as the default player for audio and video content. You can use the “Set default device” command to select a device that plays content in a specific format, such as a Blu-ray disc or a USB device. You can configure your HDMI device so that it is your primary player, and you can assign other devices to play content only when no other player is available. For example, you can set an HDMI device to be the default player for DVDs, but you can set a TV or set-top box to be the default player for Blu-ray disks.

When you connect your Android TV to your PC you’ll have to configure it to connect to the TV instead of your PC’s audio output. While the PC is connected to the HDMI input of the TV you’ll have to check its settings and change the TV’s HDMI input to the PC and set it as the default device. The process is the same for other devices. You’ll have to check their settings and set the device as default if you want to change the HDMI input device.

Check If All Hardware Devices Work Properly

The computer is the most important machine in our life.  Almost all personal computer users make use of a keyboard, mouse and monitor or display.  All these devices need to be working in perfect condition so that we can use them efficiently. Therefore, we must find out whether all these devices are working properly.

Set HDMI as the Default Playback Device

HDMI output is the default output for PC and Mac. All you need to do is to connect the cable and select HDMI as the source device. You don’t have to change anything else. You can then use the mouse and keyboard to control your TV.

To set HDMI as the default playback device in a computer, the following steps are required: 

1. Run the Settings app 

2. Click on System then choose the Display and then choose the HDMI device under the Audio device 

3. Make sure the HDMI device is the default.

Update Installed Drivers

To install additional or updated drivers on the computer, you need to turn on your PC first. Then, you need to click on the “Windows Update” icon on your computer display and follow the instructions to update your drivers. Also, you need to keep your drivers up to date for your computer to work properly and to prevent potential system crashes or other hardware issues.

Enable Audio Controllers

The audio controller is a device used to play audio files for games and entertainment applications. It is a component of the operating system and is used primarily to playback digital audio. It is a hardware device that is integrated into the system.

The audio controller is a device used to play audio files for games and entertainment applications. It is a component of the operating system and is used primarily to playback digital audio. It is a hardware device that is integrated into the system.

Some computer programs use audio controllers which let a user play a sound through a computer. To use these controls, users must right click on the speaker icon in the taskbar, then click “Open Properties”. The default path is C:\Users\(username)\AppData\Local\Microsoft\Windows\Audio\ and is usually found in a folder called “Default Audio Devices”. In this folder are listed files called C:\Users\(username)\AppData\Local\Microsoft\Windows\Audio\(filename).wav

Reinstall Audio Drivers

Installing sound card drivers is the first step towards audio output. Sound drivers allow the computer to play sounds from various devices. If you are using a notebook, you will need to install the sound card driver for your notebook. You can download the driver directly from the manufacturer/vendor website.

Use Windows Troubleshooter

Windows 10 has a built-in troubleshooter to fix sound problems. It is built in to help find solutions, however, it is a very rudimentary troubleshooter that can only solve a handful of sound problems. It does not diagnose problems, nor can it fix systems for you. If Windows 10 is having sound problems other than the ones listed above, I recommend calling the manufacturer of your sound card for support. 

To fix sound in a computer, you must set the following: “On”, “Volume”, and “Mixer”. Start by clicking the Start button, and then click Run. In the Open box, type Troubleshooting, and then click Troubleshooting. In the results window, click Troubleshooting and Sound.


If you have an HDMI sound system, and it’s not working, you may have a problem with your HDMI. I have mentioned a few things in this article to help you fix the problem. If you have a sound system, it is important to look for the right type of sound card and other accessories.
