How to Fix HDMI Audio Device Not Detecting in Windows 10/11
Below are several hacks you can try to help solve the audio problem. Ensure you follow them in order for better results.
Method 1: Reconnect Your TV or Monitor
As you may have witnessed before, reconnecting most devices, not just TVs and monitors, helps you resolve many issues. So, you could try unplugging the HDMI cable from both devices, and then plugging it back in and see if that helps.
If your TV or monitor has two HDMI ports, try connecting via the second one.
Method 2: Adjust the Monitor or TV Sound Settings
The volume might be low or even muted on your TV or monitor, making it impossible to hear anything from the video. Use the TV remote to increase the volume and see if that works. For the monitor, press the volume buttons either on the side or bottom, depending on its make. You could also check if you have muted your computer’s audio.
Method 3: Use the Windows Audio Troubleshooter
This tool allows you to check if your PC has issues that might be causing the audio not to be detected on your TV or monitor. Follow these steps to use the Windows Audio Troubleshooter tool on your Windows PC:
- Press the Windows + I shortcut keys to launch the Settings app.
- Go to Update & Security.
- Choose Troubleshoot on the left menu pane.
- Under the Recommended troubleshooting section on the right pane, select Additional troubleshooters.
- Choose Playing Audio, and then click the Run the troubleshooter button.
- Apply the indicated suggestions, if any.
Method 4: Set HDMI as the Default Audio Device
If you have set the computer speakers as the default audio device, you won’t get any audio on your TV or monitor. Here is how to change this setting to HDMI:
- Right-click on the sound icon in the bottom right corner of your desktop and choose Sounds.
- Switch to the Playback tab, and then click on Digital Output Service or HDMI.
- Choose Set Default on the dropdown list at the bottom, and then click OK.
If you don’t see the HDMI option, right-click on the empty space on the Playback tab and select Show disconnected devices. Right-click again and choose Show disabled devices. You can now follow the above steps to set HDMI as the default audio device.
Method 5: Restart the Windows Audio Service
Some users say that restarting the Windows audio service enabled them to solve the audio problem in Windows 10/11. These steps will guide you through doing the same:
- Use the Win + R combination to open the Run dialog box and type in “services.msc” (without quotes).
- Then click OK.
- On the next screen, scroll down the services list and right-click on Windows Audio. Then choose Restart.
- Repeat step 3 for Windows Audio Endpoint Builder.
Method 6: Update Your Audio Driver
If your audio driver is damaged or corrupted, you may experience the HDMI no sound issue. You can update the audio driver by following this simple guide:
- Press the Windows key, and then type in “device manager” (no quotes).
- Choose Open on the right menu pane.
- Double-click Sound, video, and game controllers to display the audio driver.
- Right-click on the driver, and then select Update driver.
- Click Search automatically for drivers.
- Restart your Windows PC after installing the updated driver.
The above method is quite simple, but you would be forced to always repeat it whenever you need to update any device driver, which can be exhausting. To avoid that, you could use a professional driver updater like Outbyte Driver Updater.
