“How to fix the OBS audio delay? I have been using OBS for quite some time now, but now whenever I stream content on it, there is an audio delay. What is the best way to resolve the OBS audio and video out of sync problem?”

Watching videos with audio and video delay is frustrating. You may have experienced this before when your movie has funny sounds playing a split second too early or late.

The same thing happens in OBS Studio as well: you start recording/streaming only to find that there’s a lag time between what was seen by the camera and heard through speakers because of low internet speeds (bandwidth consumption).

However, there are quite efficient ways to fix the OBS audio delay problem, and we will share information on them in this tutorial.

Moreover, one of the prominent causes behind the OBS audio delay is the malfunctioning of sound devices attached to the computer. Ensure the audio devices are working at their total capacity.
