How to Fix OBS Desktop Audio Delayed After Recording?

OBS Studio is one of the most widely used screen recording and live streaming applications in the world. It offers powerful recording features, customizable settings, multiple audio sources, and support for high-quality video capture. Whether you are recording gameplay, tutorials, webinars, or online meetings, OBS is often the first choice for creators and professionals.

However, one common issue many users encounter is desktop audio delay after recording. You may notice that the sound does not match the video timing, voices appear late, or audio gradually drifts out of sync as the recording progresses. This problem can make videos look unprofessional and frustrating to watch.

In this guide, we’ll explain why OBS desktop audio becomes delayed after recording, show you how to fix it step by step.

1. Why OBS Desktop Audio Is Delayed After Recording?

Several factors can cause OBS desktop audio to become delayed after recording. Here are the most common reasons in a short list:

• Incorrect audio sync offset settings
• OBS and Windows sample rate mismatch
• High CPU or GPU usage during recording
• Bluetooth headphone or speaker latency
• Device timestamp synchronization issues
• Variable frame rate recording problems
• Outdated audio or graphics drivers
• Recording settings that overload the system

Understanding the cause of the issue can help you apply the right solution more quickly.

2. How to Fix OBS Desktop Audio Delayed After Recording

If your OBS recordings have delayed desktop audio, try the following fixes one by one.

Fix 1: Reset Audio Sync Offset

OBS allows manual audio delay adjustments through the Sync Offset setting. If the value is accidentally changed, your desktop audio may become delayed.

Steps:

Open OBS Studio > Go to the Audio Mixer > Click the gear icon next to Desktop Audio > Select Advanced Audio Properties > Find Sync Offset and set the value to 0 ms

After resetting the offset, make a short test recording to check whether the issue is fixed.

Fix 2: Match Sample Rates

Using different sample rates between OBS and Windows often causes audio drift over time.

• In OBS: Open Einstellungen > Select Audio > Set Sample Rate to 48 kHz

• In Windows: Right-click the speaker icon and open Sound Settings > Select your playback device and open Properties and choose 48,000 Hz

Restart OBS after applying the changes.

Fix 3: Disable “Use Device Timestamps”

This OBS feature can sometimes create synchronization problems depending on your hardware or audio drivers.

Steps:

Open OBS > Locate Audio Input Capture and go to Properties > Uncheck Use Device Timestamps under the Device section

Restart OBS and test another recording.

Fix 4: Lower OBS Resource Usage

If your computer is overloaded during recording, video frames may drop while audio continues recording normally.

Reduce system load by:

• Lowering recording resolution
• Reducing FPS from 60 to 30
• Closing unnecessary applications
• Using hardware encoding such as NVENC

You can also monitor OBS statistics for:

• Rendering Lag
• Encoding Lag
• Dropped Frames

High values usually indicate hardware overload.

Fix 5: Avoid Bluetooth Audio Devices

Bluetooth devices naturally introduce latency because wireless audio requires additional processing.

To reduce delay:

• Use wired headphones or speakers
• Capture audio directly from desktop output

If Bluetooth devices are necessary, you may need to manually adjust the sync offset.

Fix 6: Record in MKV Instead of MP4

Recording directly to MP4 may sometimes create unstable files.

OBS recommends recording in MKV format first.

Steps:

Open Einstellungen and go to Output > Set recording format to MKV > After recording: Open File > Remux Recordings and convert the file to MP4

This method often improves recording stability and synchronization.

Fix 7: Update Audio and Graphics Drivers

Outdated drivers may cause compatibility and timing problems.

Update:

• Audio drivers
• GPU drivers
• USB audio device drivers

Restart your computer after installing updates.
