How to Switch the Sound From Your Laptop to TV via HDMI

See here how to switch the sound from laptop to TV via HDMI to fix the issue where the sound plays through your laptop instead of your TV.

When you connect your laptop to the TV via an HDMI cable, does the sound keep coming out from the laptop and not from the TV as if you weren’t using an HDMI cable at all?

I had this issue in one of my laptops when connected to a Samsung TV via HDMI, but I figured out how to switch the sound from the laptop to the TV. It is easier than you might think.

With your laptop connected to the TV via an HDMI cable, right-click on the speaker icon on the notification area (the right side of your taskbar) in Windows and select Sounds. On the Sound window, go to the Playback tab; select your TV from the list of devices and click on Set as Default, then Apply.

If you want a video breakdown of this process, you can watch the video below:

For some people, it might happen that as they switch their audio to the TV, suddenly there is no sound at all, even though it worked fine when the sound was coming through the laptop.

This can happen for two reasons:

  • There is an issue with your audio settings in Windows.
  • You have driver issues and need to update drivers.

Next, I will show you how to fix these issues in Windows easily.


How to Fix No Sound When Connected via HDMI by Changing Audio Settings

Below are a few different fixes you can apply to solve this issue. I’ve found these working fixes on the web, which did the job for many users.

Important: Keep your laptop connected to the TV with an HDMI cable when applying these fixes.


Fix 1: Unmute your TV in the Volume Mixer

Before trying the other fixes, check if your TV is muted in the Volume Mixer in Windows. There are cases where a Windows Updated mutes the TV. This surprisingly fixed the problem for me.

To check this:

  1. Go to the notification area and right-click on the speakers’ icon; then select Open Volume Mixer:
    Open Volume mixer on speaker icon on notification area
  2. You will see all your output devices in the Volume Mixer window, including your speakers and TV. If your TV shows the muted icon, click on it to unmute your TV.


Fix 2: Turn your TV and Connect It to your Laptop via HDMI Before Turning On your PC


Many laptops ignore the audio output when connected to an external device while turned on. If this is the case, try the solution below:

Before turning your laptop on, turn your TV on, connect it to your laptop with your HDMI cable, and only then turn on your PC. This should fix your audio issues.

If your laptop is already on, you don’t need to turn it off or restart it to try this. Keep your PC connected to your TV via HDMI, and put it on Sleep mode by clicking on the Power button and then clicking on Sleep. Wake it up, and your audio should be fine now.

If none of the previous fixes worked, you likely have driver issues.


How to Update your Audio and Graphic Card Drivers to Switch the Sound from Laptop to TV

It is also possible to fix the no audio issue by updating your audio drivers, which works most of the time. Updating your graphic card driver can also solve this issue.

Updating your graphic drivers might work because, in some cases, the audio is a part of the graphics card.
You can update your audio and graphic card drivers by using a driver updater or by updating them using Windows itself.


How to update your audio and graphic drivers with a driver updater

The quickest way to update your audio and graphic card drivers, and all your device drivers for that matter, is to do it with a driver updater.

I recommend you use Driver Booster as your driver updater; this is the one I have installed on all my Windows devices. To update your drivers:

  1. Download Driver Booster, and install it on your PC.
  2. Open the program and click on Scan. The program will scan for all the outdated drivers on your PC:

  3. After the scan, click Update Now in the upper-right corner to update all of your outdated drivers at once. If you want to update your audio and graphic card drivers, click on the Update button right next to it:

Your sound should be coming from your TV now.

(Updating audio drivers is crucial to keep your audio devices working and avoid issues like the Windows Audio Device Graph Isolation high memory usage in the task manager.)


How to update your audio driver without a driver updater

If you prefer to update the drivers manually, follow the steps below.

Updating your Audio Driver on Device Manager

  1. Enter Device Manager on the Windows Search to open the Device Manager.

  5. Windows will update your audio driver to the latest version.

  2. Right-click on your graphic card device, and select Update Driver:

  3. Select Search automatically for drivers
  4. Wait while the graphics card driver is updated to the latest version.


Conclusion

To switch the sound from your laptop to a TV via HDMI, the first thing you should try is to set your TV as the default audio output source in the audio setting in Windows.

If this doesn’t work, you should try the following steps:

  • Check if your TV is muted in the Volume Mixer in Windows
  • Turn on your TV and connect it to your laptop via HDMI before turning on your laptop.
  • Update your audio and graphic card driver through a Driver Updater or Windows.
