OBS Studio is a free and open source screen recorder compatible with Windows, macOS, and Linux, making it the first choice for recording any screen recording activities, especially for recording gameplay. With its help, you can capture any video or audio from your computer easily and quickly.

However, most users might sometimes encounter the "OBS Not Recording Audio" issue while using it for recording. If you have the same difficulty, don't fret, as you can find some feasible methods to fix the problem here. Now, let's discuss how to fix OBS not capturing audio in detail.

#Method 1. Restart/Reinstall OBS Studio

Usually, if you encounter issues while using software, you might close and restart the program first, as there might be some conflicts on your computer. Therefore, if you face the OBS not recording audio problem, you also can simply close and restart this software to fix it. 

If it's still not working, you can then reinstall OBS, because the problem sometimes might be caused by unknown errors during the installation process. Here are the steps:

Step 1. Hit the Windows logo key and R keys on your keyboard simultaneously, then enter a command line: appwiz.cpl.

Step 2. Find the OBS Studio option and right-click on it to uninstall it.

Step 3. At last, you can download and install OBS Studio from its official website, and open it to check if the problem is solved.

#Method 2. Unmute OBS on Your Computer

If you accidentally muted the OBS in the Volume Mixer, there is no doubt that your OBS cannot capture the sound. So another troubleshooting step is to check the Volume Mixer on your computer. Here's how:

Step 1. Right-click on the Speaker icon in the lower right of your screen, then open the Volume Mixer.

Step 2. Check if the speaker icon under OBS is muted. If yes, click on it to unmute OBS Studio.

Unmute OBS

Step 3. Once done, open the freeware to check whether OBS is recording the audio.

#Method 3. Check Audio Track Settings

If you select multiple audio tracks, the sound might disappear from OBS, which is why your OBS cannot capture sound. In this way, you'd better check the OBS tracks by following the below tutorials:

Step 1. Launch OBS Studio, and open the Setting window.

Step 2. Click "Audio" on the left sidebar, and next, choose the right audio device in the "Desktop Audio" and "Mic/Auxiliary" tabs. Once done, see if OBS captures audio or not. If the audio issue persists, try other solutions below.

Step 1. Press the Windows logo key on the keyboard, and enter "OBS Studio" in the search box.

Step 2. When you see the OBS Studio icon, right-click on it and select the "Run as administrator" option.

If a default audio device already supports recording, the OBS Studio won't capture the new one you plug in. So, manually setting Speakers as the default audio device is also a workable solution to solve the OBS not capturing audio issue. The steps are as easy as 1-2-3:

Step 1. Right-click the Speaker icon and select the Sounds option.

Step 2. Next, a window will pop up. You need to select the Speakers on the Playback tab, and choose the "Set Default" option.

Step 1. Open OBS Studio, then click "Settings" in the bottom right.

Step 2. Click "Output" on the left panel. Next, set Bitrate to 128 and type 3500 in the box. If needed, you can also customize the Rate Control option.

Step 3. Uncheck the Use CBR option and click OK to apply all changes you made.
