The delay can vary from a slight delay that is barely noticeable to a significant delay that disrupts the viewing experience. Audio delay can happen due to various reasons, such as hardware limitations, software settings, or incorrect configurations.

#1 Check Hardware and Drivers

Begin by ensuring that your computer’s hardware, including audio and video drivers, is up to date. Outdated drivers or incompatible hardware can lead to synchronization issues. Visit the manufacturer’s website or use appropriate software to update your drivers.

#2 Adjust Audio Offset

Both Streamlabs OBS and OBS offer an audio offset feature, allowing you to manually adjust the audio delay. To access this feature, follow these steps:

For Streamlabs OBS

  1. Open Streamlabs OBS.
  2. Go to the Mixer tab and locate the audio source you want to adjust.
  3. Right-click on the audio source, choose Filters, click the + icon, and select Offset/Gain. Or, just click Filters on the top menu, select Advanced Audio Properties in the pop-up menu, and tweak the Sync Offsite to a negative number.
  4. Adjust the audio delay as needed.


  1. Open OBS.
  2. Right-click on the audio source, select Filters, click the + icon, and choose Render Delay.
  3. Then, adjust the audio delay according to your requirements.

Experiment with different values until you achieve the desired synchronization. Preview your stream or recording to confirm the changes.

#3 Consider Audio Buffering

Audio buffering can sometimes resolve audio delay issues.

To enable audio buffering in Streamlabs OBS:

  1. Open Streamlabs OBS and go to Settings.
  2. Navigate to the Advanced section.
  3. Check the box that says “Enable Advanced Encoder Settings.
  4. Adjust the Audio Bitrate to a higher value, such as 160 or 192 Kbps.


Navigate to the Audio tab in the settings and increase the Buffer Size (ms) value. Experiment with different buffer sizes to find the optimal setting for your system.

#4 Reduce Video Processing Load

If your computer is struggling to handle the encoding and processing tasks, it can cause audio delay. Try reducing the workload by lowering the video resolution, adjusting encoding settings, or closing unnecessary applications running in the background.

Audio delay can significantly impact the quality of your live streams or video recordings. Fortunately, by following the steps outlined above, you can mitigate and resolve audio delay issues to achieve the OBS audio delay fix. Remember to keep your hardware and drivers up to date, adjust audio offsets, enable audio buffering, reduce video processing load, utilize audio sync tools, and consider hardware upgrades if needed.
