No Audio on Screen Recording? How to Fix It on Any Platform

You hit record, captured everything on screen, and then played it back to silence. No audio in a screen recording is one of the most common frustrations for students, remote workers, and content creators — and it almost always comes down to a settings issue, not a broken app or computer. This guide walks through the exact fixes for Windows, Mac, iPhone, Android, and OBS so you can find and solve the problem in minutes.

No Audio on Screen Recording? How to Fix It on Any Platform

Why Your Screen Recording Has No Audio

Before jumping into platform-specific steps, it helps to understand the three reasons this happens. Most cases fall into one of these categories:

Why Your Screen Recording Has No Audio

• Audio input was never selected. Recording software typically defaults to no audio source. You have to actively choose a microphone input, system audio, or both before starting the recording.

• OS-level microphone permission is blocked. Windows, macOS, and iOS all require apps to be explicitly granted microphone access. A recent update or a fresh install may have revoked it without any notification.

• The app recorded the wrong source (or none at all). Some apps separate microphone audio from system audio. If you needed both and only one was enabled, the track you wanted will be missing.

The good news: almost every fix in this guide is a settings change. You will not need to reinstall anything.

Fix No Audio on Screen Recording — Windows 10 and 11

Windows has two common recording tools: the built-in Xbox Game Bar and third-party apps. Work through these steps in order.

1. Check audio toggles in Xbox Game Bar. Open Xbox Game Bar (Windows + G), go to the Audio widget, and confirm that both the system audio output and your microphone input are not muted. The capture widget also has separate toggles for microphone on/off during recording — make sure yours is enabled before you start.

   

2. Verify microphone permission in Windows Settings. Go to Settings > Privacy & Security > Microphone. Confirm that “Microphone access” is turned on at the system level, and that the specific recording app you are using also has permission toggled on in the list below.

   

3. Check the volume mixer and input device. Right-click the speaker icon in the taskbar and select Sound settings. Under the Input section, confirm the correct microphone is selected as the default device. Also open the Volume Mixer and check that your recording app is not muted or near zero volume.

   

4. Using a third-party recorder? Apps like Bandicam, Camtasia, or Action! each have their own audio source selectors inside the app’s recording settings. Look for an “Audio” or “Sound” tab and confirm a valid input device is assigned. If you are using OBS, see the dedicated OBS section below.

Fix No Audio on Screen Recording — Mac (QuickTime and Built-in Recorder)

QuickTime Player is the default screen recorder on macOS, and it has one critical behavior that catches almost everyone: it defaults to no microphone input.

1. Select a microphone in QuickTime’s options panel. When you open a new screen recording in QuickTime (File > New Screen Recording), click the small dropdown arrow next to the record button. Under the “Microphone” section, select your built-in microphone or any connected audio device. If this is set to “None,” QuickTime will record silent video every time.

2. Understand the system audio limitation. QuickTime cannot capture internal Mac audio (music, app sounds, video playback) natively. If you need to record what is playing through your Mac’s speakers, you must install a virtual audio driver. BlackHole is a free, modern option — it creates a virtual audio device you route through QuickTime’s microphone input to capture system output. Soundflower is an older alternative that still works on some macOS versions.

• Note: If you only need to record your voice narrating over a screen, the built-in microphone selection in QuickTime is all you need. System audio capture is only necessary if the on-screen audio is part of the recording’s content.

3. Grant microphone permission in macOS. Go to System Settings > Privacy & Security > Microphone and confirm QuickTime Player (or whichever app you are using) has access enabled. If it is not listed, it may not have requested permission yet — try starting a recording first, and macOS will prompt you.

Fix No Audio on Screen Recording — iPhone and iPad (iOS)

The iOS built-in screen recorder is straightforward, but audio is off by default in a way that is easy to miss entirely.

1. Enable the microphone before recording. This is the most commonly missed step on iPhone and iPad. Long-press the screen record button in Control Center (do not just tap it). A panel will appear showing a microphone icon labeled “Microphone Audio.” Tap it to turn it on — the icon should highlight red to indicate it is active. Then tap “Start Recording.” If you tap instead of long-press, recording starts immediately with audio off.

• Important: This setting does not persist between sessions on all iOS versions. Get into the habit of long-pressing every time to confirm the microphone status before you start.

2. Check microphone permission for screen recording. Go to Settings > Privacy & Security > Microphone and confirm that the Screen Recording feature or any third-party recording app has microphone access enabled.

3. Understand iOS system audio restrictions. Apple limits third-party apps from capturing internal audio from other apps (for example, a streaming app’s audio). The built-in screen recorder can capture microphone audio clearly, but system audio from protected apps may not be recordable regardless of settings.

Fix No Audio on Screen Recording — Android

Android’s screen recorder implementation varies by manufacturer, but the core fix is the same across most devices.

• Set the audio source before recording. Open the built-in screen recorder from the quick settings panel. Before tapping record, look for an audio or sound toggle. Most Android recorders offer three modes: Internal Sound (system audio), Microphone, or Both. Select the option that matches what you need. On Samsung devices, this is labeled “Sound”; on Xiaomi it appears as an audio source icon; on Pixel phones it is a microphone toggle in the recording controls.

• Grant microphone permission to the screen recorder app. If the microphone option is grayed out or audio is still not captured after selecting it, go to Settings > Apps > Screen Recorder > Permissions and enable microphone access.

Note: UI labels differ across Samsung One UI, Xiaomi HyperOS, and stock Android, but every current Android screen recorder includes an audio source selector. If you cannot find it, swipe through the screen recorder’s pre-record options panel before confirming the recording start.

Fix No Audio in OBS Screen Recording

OBS Studio gives you full control over audio routing, which also means there are more places for something to be misconfigured. Check these four areas in order.

1. Check the Audio Mixer panel. In the main OBS window, look at the Audio Mixer at the bottom. You should see channels for Desktop Audio and Mic/Aux. Confirm neither channel is muted (the speaker icon should not show a red line through it), and that the volume faders are visibly raised above zero. A fader silently dragged to the bottom is a frequent cause of missing audio in recordings.

   

2. Verify audio devices in OBS Settings. Go to Settings > Audio. Under the “Global Audio Devices” section, check that Desktop Audio is set to your correct output device (usually your default speakers or headphones) and that Mic/Auxiliary Audio is set to your microphone. If either is set to “Disabled,” no audio from that source will be captured.

   

3. Resolve sample rate mismatches. OBS defaults to a 44.1 kHz sample rate, but Windows often defaults to 48 kHz. If these do not match, audio may be absent or distorted. To fix it: right-click the speaker icon in the Windows taskbar, open Sound settings, find your audio devices under Playback and Recording, go to their Properties, and change the sample rate to match whatever OBS is set to. You can also change the OBS sample rate in Settings > Audio to match Windows instead.

   

4. Check track assignments for your recording output. Go to Settings > Output > Recording and confirm that at least one audio track is enabled under the “Audio Tracks” section. If all tracks are unchecked, the video file will have no audio regardless of what the mixer shows. Also verify that your audio sources in the scene are assigned to an active track under Edit > Advanced Audio Settings.

   

   

Still No Audio? Advanced Checks

If you have worked through the platform-specific steps above and the recording is still silent, try these final checks before assuming a deeper technical fault.

• Update your audio drivers (Windows). Open Device Manager, expand “Sound, video and game controllers,” right-click your audio device, and select “Update driver.” Outdated or corrupted drivers can prevent audio from being routed to recording apps.

  

• Check the export or render settings. If you recorded in an editing app like Camtasia or DaVinci Resolve, your export settings may have audio tracks disabled. Recheck output settings and re-export with audio enabled.

• Test the file in VLC. Before assuming the problem is in the recording software, open the saved file in VLC Media Player. VLC reads a wider range of audio codecs than most default players. If VLC plays audio that another player does not, the file is fine and the issue is with your playback app.

Want Better Audio Quality Once the Fix is Working?

Once your recording software is capturing audio correctly, built-in laptop microphones and phone mics can still hold your content back with background noise and low clarity. For mobile recordings, the Hollyland LARK A1 connects directly via USB-C or Lightning with no setup required and offers three-level noise cancellation — a straightforward upgrade for tutorial creators recording on iPhone or Android. For desktop vloggers and walkthrough creators, the Hollyland LARK M2 (9g, 40-hour battery life) eliminates the ambient noise that settings alone cannot fix.

Frequently Asked Questions

Q: Why does my screen recording have video but no sound?

The most common reason is that the audio input — microphone or system audio — was not enabled in the recording software before starting. Recording apps do not always default to capturing audio. Open your app’s audio settings, select an input source, and record a short test clip to confirm audio is being captured before you record the full session.

Q: How do I get sound on my iPhone screen recording?

Long-press the screen record button in Control Center (do not just tap it). A panel will appear with a microphone icon — tap it to enable microphone audio before starting the recording. Simply tapping the button starts recording immediately with audio off, which is why so many iPhone recordings end up silent.

Q: Can QuickTime record system audio on Mac?

Not natively. QuickTime can only record microphone input, not the audio playing through your Mac’s speakers. To capture internal audio, you need to install a free virtual audio driver such as BlackHole, which creates a device you can select as QuickTime’s audio input to route system sounds into the recording.

Q: Why is there no audio in my OBS recordings even though I can hear myself during the session?

Audio monitoring and audio recording are separate in OBS. You can hear yourself through the monitor while the recording track captures nothing if your audio source is not assigned to an active output track. Check the Audio Mixer for muted channels, and confirm that recording tracks are enabled under Settings > Output > Recording > Audio Tracks.

Q: My screen recording had audio before — why did it suddenly stop working?

A Windows or macOS system update is the most likely cause. Both operating systems can reset app-level microphone permissions after major updates without notifying you. Go to your OS privacy settings (Settings > Privacy & Security > Microphone on Windows or macOS) and re-enable access for your recording app.

Conclusion

Most screen recording audio problems come down to two things: the correct audio input was not selected in the recording software, or microphone permission was blocked at the OS level. Start with the section that matches your platform, check those two points first, and you will resolve the issue in most cases. If you are still stuck after those steps, the advanced checks above cover driver issues, export errors, and file playback problems.
