Initial Troubleshooting Steps

Before trying one of our solutions below, you might want to go through these troubleshooting steps:

  • Make sure that your Bluetooth audio device can support the Bluetooth version on your computer. For instance, if your speakers can only handle Bluetooth 2.0, the small bandwidth may not be able to deliver the high bit rate of the audio stream. In this case, you must find a device that supports Bluetooth 4.0.
  • You should also check if you have enough battery on your Bluetooth audio device.
  • Make sure that your Bluetooth audio device is close to your computer. Doing so will ensure a stable connection.
  • Reduce the interference by switching off nearby Bluetooth devices.

If these initial troubleshooting steps do not fix the Bluetooth audio lags, we recommend trying our solutions below.

Solution 1: Reconnecting the Bluetooth Audio Device to your Computer

One of the easiest and quickest ways to fix audio lags on your Bluetooth audio device is to reconnect it. All you need to do is unplug it from your computer, switch it back on, then reconnect it to your PC. If the audio is still lagging, you can move on to the next solution below.

Solution 2: Using the Windows Audio Playback Troubleshooter

There are many great features in Windows 10, and the built-in troubleshooters are among them. So, if you are experiencing sound lags, you can run the Windows audio playback troubleshooter. Here are the steps you need to follow:

  1. Go to the lower-right corner of your taskbar, then right-click the Sound icon.
  2. Choose Troubleshoot Sound Problems from the list.
  3. If prompted to provide permission to the app, click Yes. Doing this should let you run the Windows audio playback troubleshooter.
  4. A window will pop out. Click Next.
  5. Choose your Bluetooth audio device, then click Next.
  6. Troubleshoot the sound lag issue by following the on-screen instructions.

Solution 3: Updating your Bluetooth Driver

It is possible that you’re experiencing audio lags because you have an outdated, missing, or corrupted Bluetooth driver. So, one of the best ways to resolve the problem is by updating your drivers. There are various ways to do this. You can do it through the Device Manager:

  1. You need to go to your taskbar and right-click the Windows icon.
  2. After doing that, you must select Device Manager from the options.
  3. A new window will open. You will see a list of devices. Expand the contents of the Bluetooth category.
  4. Now, look for your Bluetooth audio device. Right-click it, then select Properties.
  5. Go to the Driver tab, then click Update Driver.

Your system should automatically find the latest driver version for your Bluetooth audio device. However, it is possible for Windows to miss the right update for your PC. So, if you’re still experiencing audio lags, the next option is to go to the manufacturer’s website. You need to find the latest version that is compatible with your system. Make sure you download the right one because if you install the wrong version, you might experience system instability issues.

Clearly, manually updating your Bluetooth audio driver can be time-consuming and risky. So, if you want a more convenient and reliable way to do this, we suggest opting for Auslogics Driver Updater. Once you activate this software program, you just need to click a button, and it will automatically recognize what system your computer is running. Moreover, it will look for the latest manufacturer-recommended drivers for your PC. The best part is, it will update and repair all your drivers. So, you can expect an overall improvement in your computer’s performance once the process is complete.
