Suppose you are watching a movie or playing a game on your Windows PC. The visual quality is top notch and everything is superb. Except for one thing: there is an annoying delay in audio output from your bluetooth speaker. You reload a rifle, but your Bluetooth headphones produce the sound effect seconds (or microseconds) later. There is no audiovisual agreement and everything is out of sync. How do you fix this?
First, check if the airplane mode is off or off. You can also try restarting your computer. If the audio output of the Bluetooth device is still not in sync with the on-screen visual, try the six (6) troubleshooting solutions listed below. We are confident that at least one of them will help fix Bluetooth lagging issue on your Windows 10 PC.
1. Solve proximity and interference problems
Distance plays an important role in determining the audio quality of wireless Bluetooth devices. Make sure your computer and the Bluetooth audio device are both within range. You should also verify that there is no form of physical obstruction (such as a wall) between your PC and the audio device. It may interfere with the Bluetooth connection and cause audio delay.
Speaking of interference, make sure the audio device is not near another device plugged into your PC’s USB 3.0 port. Microsoft warns that this could disrupt the transmission of the audio signal via Bluetooth. If, for example, you experience audio delay when using a Bluetooth speaker located near your PC’s USB port, move the speaker away and check if that fixes the problem.
We recommend that you check out Microsoft’s official guide to troubleshooting Bluetooth issues in Windows 10.
2. Reconnect the Bluetooth device
Launch the Bluetooth settings menu on your PC (Settings> Devices> Bluetooth and other devices) and turn off Bluetooth. Wait a few seconds and activate the Bluetooth reactivation.
You can also manually disconnect the Bluetooth device. Click on the Bluetooth device with audio delay issues and select Disconnect.
Reconnect the device to your PC (press the Connect button) and check if this fixes the audio sync issue.
3. Troubleshoot the connected device
If you are experiencing audio delay, poor audio quality, and other related issues while playing audio through Bluetooth, the Windows Audio Troubleshooter may resolve the issue.
Step 1: Launch the Settings menu and select System.
2nd step: Go to the Sound section and press the Troubleshoot button.
This will launch the Audio Troubleshooter in a new window. Wait for the tool to diagnose your audio devices and continue to the next step.
Step 3: Select the Bluetooth device with the audio delay problem and click Next.
The troubleshooter will further diagnose the device and immediately recommend solutions if it detects an issue affecting its output and audio quality. Follow the recommended prompt and see if that helps. Proceed to the next solution if the troubleshooter finds no problem with the Bluetooth device.
4. Run the Bluetooth troubleshooter
This is another built-in tool that can help detect and fix issues affecting the Bluetooth performance of your Windows PC.
Step 1: Launch Windows settings and select “Update & Security”.
2nd step: Access the Troubleshooting menu.
Step 3: In the “Find and fix other problems” section, select Bluetooth, and then click the “Run the troubleshooter” button.
This will launch the Windows Bluetooth troubleshooter. The tool will diagnose your PC and automatically attempt to fix any Bluetooth-related issues it detects. During this time, all active Bluetooth devices connected to your PC will be disconnected (and reconnected). You don’t have to worry, however; it will not mess up your device settings.
The troubleshooter will notify you of any Bluetooth issues it has diagnosed and resolved. Try playing a media file (preferably a video) on your computer and check if the audio delay issue has been eliminated.
5. Check the bluetooth device
Sometimes the problems can be with the connected Bluetooth device, not your PC. If the device is battery-powered (for example, a wireless headset or portable speaker), check that it is sufficiently charged. You can also try restarting or resetting the device. Refer to the device’s instruction manual for how to troubleshoot connectivity and playback issues.
6. Disable audio enhancements
Tinkering with audio enhancements can help you get louder and better sound on your PC, for wired and wireless devices. However, sometimes these improvements result in audio distortion, audio delay, and other issues. Follow the steps below to disable all audio enhancements for the affected Bluetooth device.
Step 1: Go to the Windows Sound settings menu (Settings> System> Sound).
2nd step: Check that the affected Bluetooth device is the selected output device. Click Device Properties to continue.
This will launch the Bluetooth device’s Properties page.
Step 3: Scroll down to the bottom and click on “Additional device properties”.
Step 4: In the new window, go to the Enhancements tab. Check the “Disable all enhancements” box and press OK to save the changes.
To add to the solutions above, we recommend that you restart the program / application where you are experiencing the audio delay. If it’s a game, close it and relaunch it. And if the problem is specific to videos, restart the media player or use another app. Finally, you should also check that the bluetooth driver and the operating system of your PC are up to date.
