6 Best Ways to Fix Bluetooth Delay on Windows 10

Say you’re watching a movie or playing a game on your Windows PC. The visual quality is top-notch, and everything looks great. Except for one thing: there’s an annoying delay in audio output to your Bluetooth speaker. You reload a rifle, but your Bluetooth headphones produce the sound effect some seconds (or microseconds) later. There’s no audio-visual agreement, and everything is out-of-sync. How do you fix this?

First, check whether Airplane Mode is disabled or turned off. You could also try restarting your computer. If the Bluetooth device’s audio production is still not in sync with the on-screen visual, try the six (6) troubleshooting solutions listed below. We’re confident that at least one of them will help resolve the Bluetooth delay issue on your Windows 10 PC.

1. Troubleshoot Proximity & Interference Issues

Distance plays an important role in determining audio quality with wireless Bluetooth devices. Make sure your computer and the Bluetooth audio device are both within range. You should also check that there isn’t any form of physical obstruction (a wall, for example) between your PC and the audio device. This could interfere with the Bluetooth connection and result in an audio delay.

Speaking of interference, check that the audio device isn’t close to another device plugged to 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’re experiencing audio delay while using a Bluetooth speaker that’s nearby your PC’s USB port, move the speaker away and check if that fixes the issue.

We recommend checking out Microsoft’s official guide on fixing Bluetooth problems in Windows 10.

2. Reconnect Bluetooth Device

Launch the Bluetooth settings menu on your PC (Settings > Devices > Bluetooth & other devices) and toggle off Bluetooth. Wait for a couple of seconds, and toggle re-enable Bluetooth.

Follow the recommended prompt, and see if that helps. Proceed to the next solution if the troubleshooter doesn’t find any problem with the Bluetooth device.

The troubleshooter will notify you of the Bluetooth problems it diagnosed and fixed. Try playing a media file (preferably a video) on your computer and check if the audio delay issue has been eliminated.

5. Check Bluetooth Device

Sometimes, the issues could be from the connected Bluetooth device, not your PC. If the device is battery-powered (perhaps a wireless headphone or portable speaker), check that it is sufficiently charged. You could also try restarting or resetting the device. Refer to the device’s instruction manual to learn how to troubleshoot connectivity and playback issues.

6. Disable Audio Enhancements

Tinkering with Audio Enhancements might help you get loud­er & bet­ter sound on your PC—for wired and wireless devices. However, these enhancements sometimes 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).

Step 2: Check that the affected Bluetooth device is the selected Output device. Click Device properties to continue.

Sync Things Up

To add to the solutions above, we recommend restarting the program/app you’re experiencing the audio delay on. If it’s a game, close and relaunch it. And if the issue is peculiar to videos, restart the media player or use an alternate app. Finally, you should also check that your PC’s Bluetooth driver and operating system are up-to-date.
