Yes, you can stop the sound from your laptop when using HDMI to TV. The main way is to change your audio output device in Windows or Mac settings to your TV speakers.
This is a common problem that drives people crazy. You plug in the cable and get sound from both places at once. It makes a weird echo and ruins your movie night.
I’ve fixed this issue many times for friends and family. The good news is that it’s usually a simple setting change. You don’t need to be a tech expert to get it right.
This guide will show you the best ways to fix the audio. We’ll cover Windows, Mac, and even some quick tricks. You’ll have quiet from your laptop in no time.
Why Your Laptop Sound Keeps Playing
Let’s talk about why this happens in the first place. Your laptop is trying to be helpful, but it gets confused.
When you plug in the HDMI cable, it sends both picture and sound to your TV. Your laptop thinks you might want sound from both devices. So it keeps its own speakers on as a backup.
This isn’t a broken cable or a bad TV. It’s just how most computers are set up by default. They don’t automatically switch the audio output for you.
Think of it like having two radios playing the same station. You only need one, but both are on. You have to turn one off manually.
The same thing happens with your laptop audio over HDMI. You need to tell your computer where you want the sound to come from. Once you do that, the problem is solved.
According to Microsoft’s support pages, Windows tries to detect new audio devices. But sometimes you need to pick the right one yourself.
How to Stop Sound from Laptop When HDMI to TV on Windows
This is the most common fix for Windows users. I use this method myself every time I connect to my TV.
First, right-click the speaker icon in your taskbar. It’s down in the bottom right corner of your screen. Choose “Open Sound settings” from the menu that pops up.
Look for the section called “Output.” You’ll see a dropdown menu with audio device options. Your TV should be listed there, often with its brand name.
Click on your TV’s name in that dropdown menu. This tells Windows to send all sound to your TV speakers. Your laptop speakers should go quiet right away.
If you don’t see your TV listed, try unplugging and re-plugging the HDMI cable. Sometimes Windows needs a fresh connection to detect the TV properly.
You can also press Windows key + P on your keyboard. This brings up the projection menu. Choose “Second screen only” or “Duplicate” based on what you need.
The Microsoft Support site has more tips for audio issues. They confirm that picking the right output device is key.
How to Stop Sound from Laptop When HDMI to TV on Mac
Mac users have a similar process but with different menus. Apple makes it pretty easy once you know where to look.
Click the Apple menu in the top left corner of your screen. Choose “System Settings” from the dropdown list. Then click on “Sound” in the sidebar.
You’ll see an “Output” tab at the top of the sound window. Click on that tab to see all your audio output options. Your TV should appear in the list of devices.
Select your TV from the list of output devices. The sound should switch to your TV immediately. Your MacBook speakers will stop playing at that point.
If your TV doesn’t show up, check your HDMI connection first. Make sure the cable is plugged in firmly at both ends. Sometimes a loose connection causes detection problems.
You can also try restarting your Mac with the HDMI cable connected. This often helps the system recognize the TV properly on startup.
Remember, learning how to stop sound from laptop when HDMI to TV on Mac is about finding the right menu. Once you do it once, you’ll remember it forever.
Check Your TV’s Audio Settings Too
Sometimes the problem isn’t just on your laptop side. Your TV might have settings that affect the audio flow.
Grab your TV remote and look for the settings or menu button. Navigate to the audio or sound settings section. Different brands call this by different names.
Look for an option called “Audio Output” or “Sound Output.” Make sure it’s set to “TV Speakers” and not “External Speakers” or “Audio Out.”
Some TVs have an “HDMI Control” or “CEC” setting. This lets devices talk to each other over HDMI. Turning this on might help your laptop and TV communicate better.
If you have a soundbar or home theater system, check those connections too. The audio might be routing through extra equipment you forgot about.
I once spent an hour trying to figure out how to stop sound from laptop when HDMI to TV. The problem was my soundbar was set as the default. Once I changed the TV setting, everything worked perfectly.

Use the Volume Mixer for App Control
Windows has a handy tool called the Volume Mixer. It lets you control sound for each program separately.
Right-click the speaker icon in your taskbar again. This time choose “Open Volume Mixer” from the menu. You’ll see sliders for different applications.
Find the program that’s playing sound on your laptop. It might be your web browser, media player, or video app. Slide its volume all the way down to zero.
This is a quick fix when you need to stop sound from laptop when HDMI to TV for one app. Other apps can still use the TV speakers normally. It’s like muting just one person in a group chat.
This method works great for video calls or presentations. You can have your slides on the TV with sound, but mute other notifications on your laptop.
The Volume Mixer doesn’t change your main audio output device. It just controls individual program volumes. Use it along with the output device change for best results.
Learning how to stop sound from laptop when HDMI to TV sometimes means using multiple tools. The Volume Mixer is one of those useful extras that comes in handy.
Update Your Audio Drivers
Old or broken audio drivers can cause all sorts of problems. Drivers are the software that lets your hardware talk to Windows.
Press Windows key + X on your keyboard. Choose “Device Manager” from the menu that appears. Look for “Sound, video and game controllers” and click the arrow next to it.
Right-click on your audio device (often Realtek or Intel). Choose “Update driver” from the context menu. Let Windows search for the best driver online.
If Windows says you have the best driver already, try uninstalling it instead. Right-click the audio device and choose “Uninstall device.” Then restart your computer.
Windows will automatically reinstall the driver when it starts up again. This fresh install often fixes weird audio routing issues.
You can also visit your laptop manufacturer’s website. Look for the support or downloads section. Search for audio drivers specific to your laptop model.
Updated drivers help when you’re trying to figure out how to stop sound from laptop when HDMI to TV. They ensure your hardware communicates properly with new devices like your TV.
Change Default Communication Device
Windows has separate settings for communication apps like Skype or Zoom. These might be overriding your main audio settings.
Go back to your Sound settings by right-clicking the speaker icon. Click on the “Sound Control Panel” link on the right side. This opens the older, more detailed sound settings.
Click on the “Playback” tab at the top. You’ll see a list of all your audio output devices. Right-click on your TV and choose “Set as Default Device.”
Then right-click on your TV again. This time choose “Set as Default Communication Device.” This tells Windows to use your TV for calls and chats too.
Now both regular audio and communication audio will go to your TV. Your laptop speakers should stay completely quiet for all types of sound.
This is a more complete solution for how to stop sound from laptop when HDMI to TV. It covers all the different ways Windows handles audio output.
The National Institutes of Health discusses technology accessibility. Proper audio routing helps people with hearing needs use assistive devices correctly.
Disable Your Laptop Speakers Temporarily
If nothing else works, you can just turn off your laptop speakers. This is a nuclear option, but it gets the job done.
Go to Device Manager again (Windows key + X, then Device Manager). Find your audio device under “Sound, video and game controllers.” Right-click on it and choose “Disable device.”
Your laptop speakers will stop working completely. All audio will have to go through your TV or other connected devices.
Remember to re-enable the speakers when you unplug from your TV. Right-click the disabled device and choose “Enable device.” Your laptop speakers will work again.
This method is good for long movie marathons or gaming sessions. You won’t have to worry about audio switching back accidentally.
It’s not the most elegant way to stop sound from laptop when HDMI to TV. But sometimes you just need the problem to go away so you can enjoy your show.
I only use this method when I’m having a party and don’t want any audio mistakes. It’s a surefire way to keep laptop speakers silent.
Check for Audio Enhancements
Some laptops have special audio software that might interfere. Brands like Dell, HP, and Lenovo add their own sound tools.
Look for audio icons in your system tray beyond the basic Windows speaker. They might have names like “Audio Control,” “Sound Blaster,” or “Dolby Digital.”
Open these audio control panels if you find them. Look for settings related to audio output or device detection. Some have options to automatically switch outputs when you plug in a cable.
You might need to disable these enhancements temporarily. They sometimes try to “help” by keeping multiple outputs active. This is exactly what causes our problem.
Try setting these tools to “Stereo” or “Direct Output” mode. Fancy surround sound modes can confuse the simple HDMI connection.
Learning how to stop sound from laptop when HDMI to TV means checking all audio software. Don’t just look at Windows settings – check manufacturer tools too.
The FTC Consumer Advice site talks about electronics settings. They remind users that added software can change how devices work together.
Use a Different Audio Cable
HDMI carries both video and audio in one cable. But you can use separate audio cables if you prefer.
Some people use an HDMI cable for video only. Then they run a separate audio cable from their laptop’s headphone jack to their TV or sound system.
This method gives you more control over the audio path. You can easily mute your laptop by unplugging the audio cable. Or use a physical switch on an audio interface.
You’ll need a 3.5mm to RCA cable or similar adapter. Plug the 3.5mm end into your laptop’s headphone jack. Connect the RCA ends to your TV’s audio input ports.
Then change your laptop’s audio output to the headphone jack. Your HDMI cable will only handle the video signal this way.
This is an alternative approach to how to stop sound from laptop when HDMI to TV. It separates the audio and video signals completely.
I’ve used this method with older TVs that have weak HDMI audio support. Sometimes the separate audio connection just works better with certain equipment.
