Why ‘OBS Audio and Video Out-of-Sync’ Happens

The issue of ‘OBS audio video out-of-sync’ can occur due to various factors, and understanding them can help you determine which solution is best to apply. So, before getting into the quick fixes, here are some reasons why this might happen:

• Inconsistent Frame Rates. If the frame rate is not set correctly, it can cause video frames to lag behind or ahead of the audio, resulting in ‘OBS audio video out-of-sync’ problems.
• Incorrect Audio and Video Settings. Suppose the settings in OBS don't match the ones of the input devices; it can cause desynchronizations.
• Using Capture Devices. Most of the time, using devices for video and audio capture, like webcam and external mic, can cause mismatches in timing.
• Hardware Performance Issues. Having low CPU or GPU performances can cause the program to experience delays, especially in high-resolution video or multiple sources.
• Conflicting Software. Other active programs can interfere with OBS performance as well, leading to frame drops or audio delays.

By identifying which of these potential factors affects the out-of-sync problem, you can quickly resolve the audio out of sync with video in OBS Studio . Proceed to the next part to see the quick fixes you should try.

Fix 1. Add Sync Offset to Fix OBS Audio Delay

The Sync Offset feature of the program permits you to manually adjust the timing of your audio relative to the video. Doing so is particularly useful when there’s a consistent ‘OBS audio video out of sync’ issue, and you have to push the audio forward or use the background to straighten it properly. Thus, to shift the audio track to line up with the video’s timing, follow the detailed steps below:

Step 1Once the OBS Studio is opened, head to the "Audio Mixer" section, then locate the audio source that is out of sync; it could be your mic or an external audio input.

Step 2Click the "Settings" button beside that audio source and choose "Advanced Audio Properties". Here, you’ll see the "Sync Offset" column, where you can change the audio timing.

If the audio lags behind, put a positive value like 200 ms. If it is ahead of the video, set a negative value like -200 ms. You can keep testing on it until you get the proper sync.

Step 3If satisfied, click the "Close’ button to save the settings. Test the sync now by recording a short video first, then play it back to see if the ‘OBS audio video out-of-sync’ has been resolved.

Fix 2. Add Custom Sound Settings to Fix OBS Audio Delay

If you’re utilizing an external microphone or an audio interface, you can try adjusting the OBS audio settings to lessen the delays. Since the issues of OBS video audio out of sync can sometimes be caused by mismatched configurations between OBS and your audio device, modifying the sample rate and more audio device settings can minimize the latency and fix sync issues.

Step 1Inside the OBS Studio, head to "Settings" from the control tab in the bottom-right corner and go to the "Audio" tab, where you can adjust audio devices.

Step 2Under the "Global Audio Devices", make sure the audio input devices, e.g., external mic, are selected. Then, scroll down to the "Sample Rate" section and set it to 48 kHz; please ensure it matches the sample rate of your microphone.

Step 3Furthermore, you can head to the "Sound Settings" in your computer system directly. Click the "More sound settings" option from the "Advanced" section; from the mini window, select your playback device, then click the "Properties" button.

Go to the "Advanced" tab, and set the highest version of Hz now that matches your OBS sample rate settings. Click the "OK" button once done.
