Reason 2. Bluetooth Connectivity

Other than bugs, there is a possibility that the Bluetooth device you are using to play the audio is facing connectivity issues. Not just that, headphones or speakers sometimes can also introduce latency, especially when they are outdated and support low-quality features.

Solution: To resolve the audio delay, it is better to change the device and opt for its updated version to enjoy a better listening experience. In addition, check for the connectivity settings and reconnect the devices with Bluetooth to ensure robust connection.

Reason 3. Audio Settings

Last but not least, incorrect audio settings can also cause lag in the soundtracks and affect the overall sync. If you are considering a device, its sound settings can affect the audio quality. However, if you are using a certain app like VLC, its incorrect audio delay settings can also lead to sound delays issues.

Solution: No matter if you are playing audio on built-in tools or using any app, changing the sound settings can resolve the lag issues. Follow the guidelines mentioned below and see how you can reset the audio setting on iOS and Android:

For iOS

Part 2. Resolving Audio Delay in Windows/Mac [Causes + Solution]

Other than mobile phones, many users prefer to play certain videos on PCs or MacBooks to enjoy clear and crisp sounds. However, sound delay is a similar problem that happens if they are using a certain app to play the music. This situation can be frustrating; hence, to resolve this, we have listed the reasons to determine what causes lag issues while offering possible solutions:

Reason 1. System Sound Settings

Incorrect system settings such as mismatched sample rates or bit depths can also cause audio syncing issues in the operating systems. Hence, if they are not aligned properly, there are chances that you might face lag issues while playing any sound.

Solution: To resolve the delay issues, it is suggested to troubleshoot the sound settings. Through this, your sound quality will be boosted and synced together to offer a better listening experience. Here is how you can troubleshoot the system settings on your PC.

For Windows

Step 1. On your PC, launch the settings and tap on the "Sound" option from the right side of the screen to choose "Troubleshoot" from the following display.

Reason 2. Faulty Cables or Adapters

When facing audio-video lags, there is a chance that the cables or adapters, especially USB or HDMI, are faulty or of poor power quality. Due to this, the audio transmission on your system is affected, limiting your ability to hear sound properly.

Solution: To prevent audio delay, it is advised that the faulty cables be replaced so that you can enjoy sounds clearly. If replacing them costs you then look for the possible damage and try to fix them immediately.

Reason 3. Third-Party VPN Interference

If you are playing video online and your VPN is not, you will face lag issues because VPNs have the capability to slow down the internet speed. By doing this, the processing time increases, and sound delays are experienced while using any application.

Solution: To ensure your video or applications have better processing time, it's better to turn off the VPN running on your device. Once done, you will see a noticeable clarity in the audio quality, letting you enjoy clear and synced sounds.
