Screen mirroring is one of the easiest ways to enjoy movies, YouTube videos, presentations, games, and photos from your phone, tablet, or computer on a bigger TV screen. Instead of watching everything on a small display, you can instantly mirror your device to a smart TV or a TV connected through a streaming device.
However, one frustrating problem many users run into is when screen mirroring works perfectly, but there’s no sound on the TV. The picture appears without any issues, but the audio continues playing on the phone or laptop, or doesn’t play at all. This issue can happen with Android phones, iPhones, Windows 11 or Windows 10 PCs, MacBooks, Samsung Smart TVs, LG TVs, Sony TVs, TCL TVs, Roku TVs, Fire TV, Chromecast, and many other devices.
This guide walks you through every solution in a simple way so you can get both video and audio working properly during screen mirroring.
There Is No Sound on Screen Mirroring on TV (Fixed)
To fix no sound during screen mirroring on your TV, first increase the TV volume and make sure it isn’t muted. Next, verify that your phone or computer is sending audio to the TV instead of its own speakers. Restart both devices, reconnect screen mirroring, update the TV and device software, and check whether the app you’re mirroring supports audio playback. If the issue continues, reset your TV’s sound settings or reconnect the devices from scratch.
Instead of randomly changing settings, follow the steps below in order..
Step 1: Check the TV Volume and Sound Settings
Start with the simplest solution because it solves the problem more often than people expect.
Make sure your TV volume is turned up, and that Mute isn’t enabled. Try increasing the volume using the TV’s original remote rather than your phone or streaming app.
Next, open the TV’s Sound Settings and confirm that the correct speaker output is selected. If your TV is connected to an external soundbar or home theater system, make sure that device is powered on and working properly. Sometimes the TV sends audio to a disconnected sound system, making it seem like screen mirroring has no sound.
If available, switch the audio output back to the TV Speakers and test screen mirroring again.
Step 2: Disconnect Bluetooth Audio Devices
Many people forget that their phone or computer is still connected to wireless earbuds or Bluetooth speakers.
When this happens, the mirrored video appears on the TV while the sound continues playing through another Bluetooth device.
Open the Bluetooth settings on your phone, tablet, or computer and disconnect every paired audio device. After disconnecting them, reconnect screen mirroring and check whether the TV starts playing audio.
This is one of the most common causes of missing audio, especially after using wireless headphones.
Step 3: Select the Correct Audio Output Device
If you’re mirroring from a Windows PC, the computer may still be using its internal speakers.
Open the Sound Settings in Windows and look at the current Output Device. If your TV appears in the list, select it as the default playback device.
On a Mac, click the Control Center, open Sound, and choose your TV as the audio output.
On an Android phone, open the media output controls if available and verify that the TV is selected.
On an iPhone, open Control Center, tap AirPlay, and confirm that both video and audio are directed to the television.
Once the correct output is selected, play a video again to test the sound.
Step 4: Disconnect and Reconnect Screen Mirroring
Wireless connections occasionally develop temporary communication errors.
Stop screen mirroring completely on both devices instead of simply closing the app.
Turn off screen mirroring from your phone, tablet, or computer. Then remove the connected device from your TV’s screen mirroring history if that option is available.
Wait about thirty seconds before reconnecting.
Creating a fresh connection often restores both audio and video transmission.
Step 5: Restart Both Devices
Temporary software glitches are another common reason for audio problems.
Restart your phone, laptop, tablet, or computer completely.
Then restart the TV by turning it off, unplugging it from power for about one minute, and plugging it back in.
After both devices restart, reconnect screen mirroring and test the sound again.
This simple step clears temporary memory issues that may interfere with wireless audio streaming.
Step 6: Make Sure the App Supports Audio Mirroring
Not every application allows audio to be mirrored.
Some streaming services have Digital Rights Management, also known as DRM, which limits screen mirroring or blocks audio entirely.
If you’re experiencing no sound while using a particular app, try opening YouTube or another free video and mirroring it to the TV.
If audio works there but not in the original app, the issue is probably related to the application’s content protection rather than your TV.
Step 7: Check Your WiFi Connection
A weak or unstable wireless connection can interrupt audio while allowing video to continue.
Make sure both your TV and your phone or computer are connected to the same WiFi network.
If possible, move closer to your wireless router.
Avoid downloading large files or streaming multiple high-resolution videos on other devices while using screen mirroring.
A stronger network connection helps maintain smooth audio and video synchronization.
Step 8: Update Your TV Software
Older firmware can contain bugs that affect screen mirroring.
Open your TV’s Software Update or System Update menu and check whether a newer version is available.
If an update is found, install it and allow the TV to restart.
Manufacturers frequently release updates that improve compatibility with newer phones, tablets, and computers.
Once the update finishes, reconnect screen mirroring and check the audio again.
Step 9: Update Your Phone or Computer
Outdated operating systems can also cause compatibility issues.
Install the latest updates available for your device.
- For Windows, install the newest Windows Updates.
- For Android, check for System Updates in Settings.
- For iPhone, install the latest iOS update.
- For Mac, install the latest macOS update.
Keeping both devices updated ensures they use the latest wireless display and audio protocols.
Step 10: Reset the TV Sound Settings
If sound still doesn’t work, reset the TV’s audio settings.
Open your TV’s Sound Settings and look for Reset Sound, Reset Audio Settings, or a similar option.
This restores the default audio configuration without affecting your installed apps or network settings.
After resetting the sound settings, reconnect your device and test screen mirroring again.
Step 11: Reset the Screen Mirroring Connection
Sometimes the saved pairing information becomes corrupted.
Remove the paired device from your TV.
Then delete the TV from your phone’s, tablet’s, or computer’s remembered wireless display devices.
Start the pairing process from the beginning.
Creating a completely new connection often fixes audio issues that survive normal reconnect attempts.
Step 12: Test Another Device
If you’re unsure whether the problem is coming from your TV or your original device, perform one final test.
Mirror a different phone, tablet, or computer to the same TV.
If the second device plays sound correctly, the issue is likely with the original device’s settings.
If neither device produces sound, the TV or its software configuration is probably responsible.
This comparison quickly narrows down where the problem actually exists.
FAQs
Why does screen mirroring show video but no sound?
This usually happens because the audio output is still set to your phone, computer, Bluetooth headphones, or another playback device instead of the TV. It can also result from temporary software glitches or unsupported apps.
Why is my TV muted only during screen mirroring?
Your TV may be using the wrong audio output, an external sound system, or outdated firmware. Restarting the TV and checking its sound settings usually resolves the issue.
Why does audio still play through my phone?
Your phone hasn’t switched its audio output to the TV. Open your device’s media output settings and select the television as the active playback device.
Does Bluetooth affect screen mirroring sound?
Yes. If Bluetooth headphones, earbuds, or speakers are connected, your phone or computer may continue sending audio to those devices instead of the TV.
Can poor WiFi cause missing sound?
Yes. A weak or unstable wireless connection can interrupt audio transmission during screen mirroring. Using a stronger WiFi signal often improves both sound quality and synchronization.
Why doesn’t sound work with certain streaming apps?
Some streaming platforms use DRM protection, which may restrict or disable audio during screen mirroring. Testing another app can help determine whether the issue is app-specific.
Will resetting the TV erase my apps?
Resetting only the sound settings does not remove your installed apps or personal data. A complete factory reset is different and should only be used as a last resort.
Summary
If there is no sound on screen mirroring, the problem is usually caused by an incorrect audio output, a connected Bluetooth device, outdated software, weak WiFi, or a temporary connection issue. By checking the TV’s sound settings, selecting the correct playback device, reconnecting the mirroring session, restarting both devices, installing software updates, and resetting the audio configuration when necessary, you can resolve the issue in most cases.
