Screen recording is a powerful feature for Windows 10 users, whether you’re recording a presentation, creating a tutorial, or capturing gameplay. But nothing is more frustrating than discovering your recording lacks sound.
You may see a perfect video, but the audio is either missing entirely or muffled beyond recognition. These problems aren’t uncommon and can occur due to incorrect settings, driver issues, or even privacy permissions.
The good news? Most of these problems are easily fixable once you understand how audio works on Windows during screen recording.
In this guide, you’ll learn exactly how to troubleshoot and restore clear audio, whether you’re using Xbox Game Bar, OBS Studio, or another screen recording tool.
Understanding How Audio Works in Screen Recording
To fix sound issues during screen recording in Windows 10, it helps to understand how audio is captured in the first place.
You may want to record two sources of audio: system audio (like app sounds, game effects, or music) and microphone input (your voice). Your screen recording tool must access both sources separately and sometimes combine them into one track.
Tools like Xbox Game Bar, OBS Studio, or third-party apps will allow you to select audio input sources manually. If the wrong source is selected, you may end up recording silence.

Another important factor is Windows 10’s privacy settings. If microphone access is turned off in system permissions, even the most capable software won’t be able to record voice input. Similarly, some apps don’t have access to system-level sound unless explicitly allowed.
Drivers also play a role. Outdated or conflicting audio drivers can prevent any sound from being recorded properly, even if your speakers work fine.
In short, screen recording audio depends on how well your device, system settings, and screen recorder app are configured together.
Common Causes of Missing Sound in Screen Recordings
If your video is recording fine but the audio is missing or too quiet, the root cause is usually one of these common issues.
- Wrong Audio Source Selected: Many apps default to microphone-only or a disabled source. If “Stereo Mix” or desktop audio isn’t chosen, you won’t capture internal sound.
- App Permissions Disabled: Windows privacy settings can block screen recorders from accessing your microphone or other input sources. This is especially common after Windows updates.
- Muted or Low Volume in Volume Mixer: Even if the system sound is working, your recording app might be muted in Windows’ volume mixer, which would block sound capture.
- Connected Bluetooth Speakers or Headphones: Sometimes, Bluetooth devices redirect system audio in a way that prevents screen recorders from accessing it properly.
- Audio Drivers Are Outdated or Corrupted: Faulty drivers can create mismatches between your playback device and what your screen recorder sees.
- Running Conflicting Apps: Other software, such as voice changers, virtual sound cards, or third-party enhancements, might interfere with normal audio routing.
Identifying the exact issue depends on how your system and recording tools are set up, but these are the most common culprits worth checking first.
Step-by-Step Fixes for Windows 10 Sound Issues
Now that you understand the causes, let’s walk through practical fixes that solve sound issues for most screen recording scenarios in Windows 10.
Each step is easy to follow and requires no advanced technical skill. Go through them one by one; even minor adjustments can restore proper audio capture.
Check Volume Mixer and Sound Settings
Start with the basics: check the volume mixer to make sure your screen recorder isn’t muted.
Right-click the speaker icon in the system tray and choose “Open Volume Mixer.” Scroll across and find your recorder app. If the volume is low or muted, turn it up.
Next, click “Open Sound settings” and verify that your output and input devices are active and showing levels. If they appear greyed out or unresponsive, your device might be disconnected or disabled in the Control Panel.
You should also ensure the output isn’t set to an inactive device like a disconnected headset.
Set the Right Input and Output Devices
Sometimes, audio doesn’t record simply because Windows is using the wrong audio device. It can happen after updates or when switching headphones or microphones.
Open the Sound Settings window. Under “Output,” select your speakers or headphones. Under “Input,” choose the correct microphone.
Scroll down to “Advanced sound options” and click “App volume and device preferences.” From there, make sure your screen recorder is using the correct devices for both input and output.
If you’re unsure, unplug all other audio devices and test with your default ones. Getting the right device selected often resolves missing or muffled audio during recording.
Give Microphone Access to Apps
Windows 10 restricts microphone access for privacy. If it’s turned off, no app (including screen recorders) can use it.
Go to Settings > Privacy > Microphone. Make sure “Allow apps to access your microphone” is enabled. Scroll down and check that your specific screen recorder (like Xbox Game Bar or OBS) is listed and toggled on.
Do the same under “Camera” settings if your recording includes webcam footage.
Once access is enabled, restart your recording software and try again. Often, simply granting permissions solves the issue instantly, especially after Windows updates reset privacy preferences.
Test Audio in the Recorder App (OBS, Xbox Game Bar, etc.)
Each screen recorder has its own method of handling audio. You need to verify that the correct sources have been added and are active.
For OBS Studio, open the Audio Mixer and ensure “Desktop Audio” and “Mic/Aux” are not muted. You can also add them manually in “Sources.”
In Xbox Game Bar, go to Settings > Capturing and ensure both audio sources (game and mic) are enabled.
Do a short test recording and listen to the playback. If audio levels show in the mixer but don’t play back, check your file format or player app. Sometimes, it’s a playback issue, not a recording one.
Update or Reinstall Audio Drivers
Outdated or corrupted drivers can block audio from being recorded, even if playback is fine.
Open Device Manager and expand the “Sound, video and game controllers” section. Right-click your main audio device (like Realtek or Intel) and select “Update driver.”
Choose “Search automatically for updated driver software.” If that doesn’t work, try uninstalling the driver and restarting your PC. Windows will reinstall the default one automatically.
You can also download the latest driver from your device manufacturer’s website for more control. Updating your driver often fixes compatibility issues, especially after a major Windows update or sound-related bug.
Restart Windows Audio Services
Windows runs background services that control your system audio. If they’re stuck or misbehaving, recording apps may not capture sound properly.
Press Win + R, type services.msc, and hit Enter. In the list, find:
- Windows Audio
- Windows Audio Endpoint Builder
- Remote Procedure Call (RPC)
Right-click each and select “Restart.” If any are stopped, start them manually.
Also, set their Startup Type to “Automatic” by double-clicking the entry.
Once restarted, close and relaunch your screen recording app. These services are core to audio processing and are often the hidden reason recordings go silent, even when everything seems fine.
Using OBS Studio: Configuring Audio Correctly
OBS Studio is one of the most powerful and flexible screen recording tools, but only when configured correctly. If you’re using OBS and experiencing sound issues, double-check these basic audio settings.
- Open OBS and go to Settings > Audio. Make sure “Desktop Audio” and “Mic/Auxiliary Audio” are set to the correct devices (e.g., speakers, microphone).
- In the main interface, check the Audio Mixer. Confirm that both desktop and mic inputs are showing activity bars when audio is played or you speak.
- Right-click each audio source and choose Filters. Use this to add gain, noise suppression, or monitor your audio for real-time testing.
- Add audio sources manually under Sources. If OBS fails to auto-detect sound, add “Audio Input Capture” or “Audio Output Capture” manually.
If your recording still lacks sound, preview a short test clip and export it. Sometimes, the audio is present, but your media player doesn’t support the format.
Try VLC or Audacity for confirmation. OBS can seem overwhelming at first, but once set up properly, it offers reliable and customizable audio capture.
Alternative Screen Recording Apps with Better Audio Handling
If OBS feels too advanced, here are user-friendly alternatives:
- ShareX – Free and lightweight, with good audio support and no watermarks.
- Bandicam – Offers real-time drawing and multiple audio source capture.
- FlashBack Express – Great for beginners, with simple timelines and a clear audio setup.
- Camtasia (premium) – A robust editor with built-in screen recording and layered audio control.
Each of these tools offers easier interfaces while maintaining solid audio functionality. Ideal for users who want fewer settings and faster results without troubleshooting complex input/output chains.
Final Checks: Things to Do Before Hitting Record
Before you start recording, it’s good practice to run through a quick checklist:
- Run your screen recorder as Administrator to avoid permission issues.
- Turn off unused audio devices (Bluetooth, HDMI, etc.) to avoid conflicts.
- Check sound levels in your app and Windows mixer.
- Record a short test clip and review it before committing to a full session.
- Keep sound enhancements disabled in your audio driver settings if the audio sounds distorted.
These checks can prevent last-minute problems and help you catch issues early, saving time and ensuring your recording sounds as good as it looks.
Conclusion
Screen recording without sound can be frustrating, especially when everything seems to be working visually. Fortunately, most issues on Windows 10 come down to permissions, driver conflicts, or simple misconfigurations.
Whether you’re using OBS Studio or a simpler tool like Bandicam, understanding how to manage your audio settings goes a long way. Always test your setup before important recordings and keep your drivers and system updated.
With the steps in this guide, you’ll be equipped to troubleshoot and solve sound problems confidently, so you can record with clarity, whether it’s a tutorial, meeting, or gameplay session.
