Part 2. How to Manually Fix Audio Delay in OBS Studio

This way can help you fix the OBS audio delay the next time you record or stream in OBS. It works by adjusting the settings within OBS Studio before you begin.

Step 1 Open OBS Studio.

Step 2 Look at the Sound Mixer. Find the audio that does not match the video.

Step 3 Click the Gear next to that sound.

Step 4 Pick Advanced Audio Properties from the menu. You will see Sync Offset. Change the number here. Try small changes, such as +100 or -100.

Step 5 Test your video and audio. Change the number again if it remains incorrect. Keep doing this until it matches.

Part 3. How to Fix OBS Audio Delay with Capture Card

Some capture cards, like the Live Gamer Ultra, can cause a sound delay if the drivers are too old or the settings do not match your game or system. However, you can fix this problem by updating the drivers and ensuring that your OBS settings, such as resolution and frame rate, match those of your capture card. It is because the closer they match, the better your audio and video will stay in sync.

Here is how to fix OBS audio delay with a capture card:

Step 1 Plug in the capture card.

Step 2 Get the latest driver from the main website.

Step 3 Open OBS, select Video Capture Device and pick Live Gamer Ultra.

Step 4 Click Configure Video and select the same video format your game or system uses.

Step 5 Hit OK. Set the resolution and frame rate (FPS) the same as your game. If you hear a sound delay, go to the Mixer and use Sync Offset like before. Try small numbers!

Part 4. How to Fix OBS Audio Delay Caused by Zoom Feature

Zooming in on OBS helps you show things clearly. However, if it consumes too much CPU, it can slow down your computer and cause OBS audio to become out of sync with the video. Lowering the FPS can make your computer work more easily and help keep the audio and video in sync.

Step 1 Open OBS.

Step 2 Select Window Capture. Pick what you want to zoom in on. Right-click the source. Click Filters.

Step 3 Click Crop/Pad and set how much to crop from the top, bottom, left, and right. Then, go back to the Preview. Make the window bigger or smaller.

Step 4 If audio becomes delayed, right-click the source. Go to Properties. Lower the FPS (like from 60 to 30).

Part 5. How to Fix OBS Audio Delay Caused by Cookies and Caches

Web files, such as cookies and cache, can cause issues in OBS, especially when using web sources or browser sources. You can fix it by clearing them.

1. For Chrome

Step 1 Click the Three dots. Go to Settings.

Step 2 Click Privacy and Security > Clear browsing data.

Step 3 Choose time range: All time.

Step 4 Check Cookies and Cached files.

Step 5 Click Clear data.

2. For Firefox

Step 1 Click the menu. Go to Settings.

Step 2 Click Privacy & Security.

Step 3 Scroll to Cookies and Site Data. Click Clear Data.

Step 4 Pick time range: All time.

Step 5 Check Cookies and Cache. Click Clear now.

Do this if you stream from a browser window inside OBS. It helps prevent weird sound lags.

Part 6. How to Fix OBS Audio Delay with Virtual Speaker

Using your PC as a speaker for your phone or tablet can cause sound delay. That is because it depends on Wi-Fi and Bluetooth. If you are trying to learn how to sync audio and video in OBS, try switching to wired headphones or plugging the sound directly into your computer. It helps fix the problem fast!

Step 1 Connect both devices to the same Wi-Fi.

Step 2 On your phone or tablet, turn on Bluetooth and pair it with your computer.

Step 3 On your computer, go to Control Panel > Sound > Playback. Set the phone or tablet as the default device.

Step 4 In OBS, go to Settings > Audio. Set that same device for Desktop Audio.

Step 5 If the sound is still not working, ensure the Sample Rate in your computer's sound settings and OBS match. You can try 48000 Hz.

Part 7. How to Fix OBS Audio Delay with a Plugin

Some audio problems in OBS Studio need more than just basic settings. If you are trying to figure out how to sync audio and video in OBS Studio, a plugin can help. One good OBS Studio plugin tool is ReaDelay from the ReaPlugs VST pack. It allows you to adjust the sound delay by setting the exact time.

Step 1 Go to the ReaPlugs site and download the VST plugin pack. Then, install it on your computer.

Step 2 Open OBS. Right-click the audio source that has a delay.

Step 3 Click Filters, then hit the + button. Pick VST 2.x Plug-in and name it anything you want. Now, choose ReaDelay from the list.

Step 4 Click Open Plug-in Interface. Set the delay in milliseconds to match the video. Try a few times until it sounds right.

Step 5 If it starts to lag, try turning off other filters or closing background apps.
