How to Fix OBS Audio Out of Sync Issue?

Before seeing how to fix the OBS video and audio out of sync issue, I’d like to first introduce the possible causes of the OBS Studio audio delay. Actually, there could be a variety of reasons for this issue. But the main reason is the malfunctioning of sound devices attached to the computer. When the OBS audio and video out of sync issue occurs, you can try to change the OBS settings to fix it. So just follow the four methods to fix the audio delay in OBS issue.

Solution 1. Adjust Sync Offset

This method can help you temporarily solve the audio delay in OBS issue for users who want to avoid the OBS audio out of sync issue in the future. Just read and follow to prevent the OBS audio delay issue.

Step 2. Change the “Sync Offset” value for the delayed audio source. Generally, 500 ms = 0.5 sec. This might take several tests.

Once you have figured out the correct “Sync Offset” value, close the window, and the audio will be synced with the video.

Solution 2. Customize Sound Settings

You can also fix the OBS audio delay issue by adding custom sound settings. What you should know is that OBS Studio only supports 48 kHz and 44.1 kHz.
