Troubleshoot: Why Is OBS Not Recording Mic/Desktop Audio[Solved]
Last Updated on September 14, 2021 by Robert Jackson
OBS is a great solution to those who yearn for perfect self-made movies. However, trouble occurs to some users that OBS is not recording mic sound or desktop audio.
The OBS not recording audio issue is the stumbling block on the way to a perfect video. If you want OBS to become the stepping stone of your recording, check out the steps below to fix the issue.
All the recommended methods based on our full suite of tests are all positive for the OBS not recording audio problem. Now, let’s follow the steps to find out why and how.
Method 1 Modify the audio input and output device on OBS
When you first launch OBS, it only has 2 default audio sources, Audio Input capture (microphone) and Audio Output Capture (speaker), you can find the two default audio sources on Audio Mixer.
Here, you can use your mouse to drag the slider to adjust the volume of the two sources. Make sure you haven’t drag the two volume sliders all the way to the left, because that will mute the two audio source and OBS will not record the sound from a muted audio track.
Method 2 Unmute OBS on your computer
If your OBS is muted on the system, it cannot record any sound.
To find out if it’s muted, right-click Speaker on the bottom right corner of the desktop and select Open Volume Mixer from the drop-down list.
On the Volume Mixer interface, you will see several app audios on your PC. Check if OBS and System Sounds are muted or not, unmute them if they are. The two options decide whether OBS is allowed to record any audio on your computer.
Method 3 Set the target audio device as default
When you insert a new speaker device into your computer, you may hear the sound from it but you may not record the sound from it. Such a possibility also occurs when you insert a microphone device, it can catch your voice and you cannot record the voice though.
That’s because there’s already a default audio input/output device that supports recording. If you plug in a new one, your computer won’t set it as a default recording device automatically since there’s already one. What you need to do is to manually set up the audio device as default.
This is how:
On your desktop, right-click on the Speaker, go to Sounds and move to the Recording module.
Method 4 Remove Nahimic from your PC
Nahimic is an audio manager application that can help improve the audio quality of your PC. A lot of gamers use it to make a better sound for their games.
It does have a good performance in audio enhancement, but Nahimic can conflict with OBS. Your OBS is not recording since Nahimic has taken up the audio driver and layer that OBS needs. To fix the issue is very easy, just uninstall Nahimic.
On the Start menu, click Settings, and then go to Apps.
There, locate Nahimic and choose Uninstall. Nahimic will be removed from your computer in a few seconds.
Method 5 Reinstall OBS
If none of the methods can help you, your OBS is having an undefined bug, you can reinstall it.
Initially, uninstall it. On your desktop, click Start and go to Settings > Apps.
Locate OBS and click Uninstall.
Then the uninstallation is complete, visit this page and install a new one on your computer.
Method 6 Try an OBS alternative
When all the previous methods fail to solve the problem, just switch to an alternative screen recorder to create a video. Personally, Aiseesoft Screen Recorder will be quite good.
Aiseesoft Screen Recorder is known as one of the most powerful screen record software which is similar to OBS, it has very great performance in screen recording. Case in point, you can record a lossless video with lossless audio quality.
Moreover, the program is very easy to use which is quite different from OBS, the one that needs practicing. You can use the keyboard shortcut to start recording your screen without complicated settings.
If you hanker to have a flexible recording, Aiseesoft Screen Recorder will meet your need as well. You can decide the audio source and recording area manually with one simple click. No need to mention that all the shortcuts, properties of the output, and mouse movements are all adjustable.
To find out more, you can download the app yourself and start a recording.
Tip: Mac users only – Install an audio plugin when OBS won’t record desktop audio
All Apple devices are not allowed to record internal audios, including Macs, iPad, iPhone. Apple is trying to stop its users from doing unauthorized recordings on some protected items, like songs, music on Spotify.
Such limitation is very inconvenient for Mac users when there are so many important audio playbacks on a Mac computer. For instance, the audio on a video meeting or chatting, the audio from a self-made demo, etc.
All in all, to record desktop audio with OBS, you have to insert a third-party audio driver. To find out the details of this solution, you can read the post as follow: How to Record Desktop Audio with OBS Mac.
OBS is not recording audio? Now, the problem is solved. Hopefully, all the methods above get you out of trouble and you can create a perfect video with the desired audio. And never forget the fact that when the error remains, try an alternative like Aiseesoft Screen Recorder.
