Connecting your Windows 10 computer to a TV using an HDMI cable is a great way to enjoy movies and games on a big screen, but sometimes you might find there’s no sound coming from the TV. This issue often happens because Windows doesn’t detect the HDMI audio device, or it’s not set as the default playback device. In this blog, you’ll learn easy steps to fix HDMI no sound issues, so you can get clear audio from your TV and enjoy your entertainment without frustration.
Step-by-Step Fixes
1. Set HDMI as the Default Audio Playback Device
- Connect your PC to the TV via HDMI.
- Right-click the speaker icon in your system tray → Open Sound settings.
- Scroll to Output (or “Choose where to play sound”) and look for a device labeled with HDMI.
- If you don’t see it:
- Click on More sound settings → opens the classic Sound control panel.
- In the Playback tab, right-click and check Show Disabled Devices and Show Disconnected Devices.
- When the HDMI device shows up, right-click it → Set as Default Device → Click Apply, then OK.
- Test sound: play a video or audio, and see if the TV now outputs sound.
2. Enable / Re-Enable HDMI Audio Controller
- Open Device Manager (
Win + X→ Device Manager). - Expand Sound, video and game controllers.
- Look for entries like NVIDIA High Definition Audio, AMD HDMI Audio, Intel Display Audio, or similar.
- If any of these are disabled (down arrow icon), right-click → Enable device.
- Alternatively, you can try Uninstalling the HDMI audio driver → then Restart the PC so Windows reinstalls it fresh.
3. Update or Roll Back Drivers
- In Device Manager, right-click on your graphics card under Display adapters, and select Update driver.
- Also update or reinstall the HDMI audio driver under Sound, video and game controllers.
- If the issue started after a driver update, you can roll back the graphics driver by going to its Properties → Driver tab → Roll Back Driver (if available).
4. Restart Windows Audio Service
- Press
Win + R, typeservices.msc→ Enter. - In the Services list, find Windows Audio.
- Right-click it → Restart.
- Also make sure Windows Audio Endpoint Builder is running. If not, start or restart it.
5. Reconnect & Check HDMI Cable / Port
- Unplug the HDMI cable from both your PC and TV. Wait a few seconds.
- Check that you’re using a high-quality HDMI cable that supports audio.
- Try a different HDMI port on your TV — TVs often have multiple HDMI inputs; some might not support audio or have different settings.
- Once replugged, repeat the steps to set HDMI as the default playback device.
6. Run Windows Audio Troubleshooter
- Open Settings → System → Troubleshoot → Other troubleshooters (in Windows 11) or Settings → Update & Security → Troubleshoot (in Windows 10).
- Run the Playing Audio troubleshooter. Windows will detect and possibly fix common audio problems.
- Follow on-screen instructions and apply recommended fixes.
7. Update Windows & BIOS (Optional)
- Use Windows Update to check for system updates — sometimes updates include important driver fixes.
- For laptops / desktops, check your manufacturer’s website for any BIOS or firmware updates, especially for graphics or audio chips — this can sometimes restore HDMI audio functionality.
Conclusion
HDMI audio issues (“No HDMI Audio Device Detected” on Windows 10 / 11) are common but fixable with some methodical checks: verify playback device settings, enable the HDMI audio controller, update or reinstall drivers, and use Windows’ built-in troubleshooter. With the steps above, you should be able to restore sound through your TV when your PC is connected via HDMI.
