If your vivo S50 screen recordings play back with no sound, you are not alone. This issue can make tutorials, gameplay clips, or saved calls useless, even though the video itself looks fine. In most cases, the problem is caused by recording settings, permission limits, or audio source restrictions that are easy to fix.
Why Your vivo S50 Screen Recorder Has No Audio
- The microphone or system sound option is turned off in the recorder settings.
- App permissions for microphone access are disabled.
- The screen recorder is set to record video only.
- The app you are recording blocks internal audio capture.
- Temporary software issues after an update or long uptime.
1. Check Screen Recorder Audio Settings
The screen recorder can capture video without audio if sound recording is disabled. You need to confirm which audio source is selected before starting a recording.
Open the Screen Recorder, and then tap Settings.
Tap Sound source, and then choose System sound, Microphone, or Both depending on your needs.
Start a new recording to test if audio is now included.
2. Enable Microphone Permission
If microphone access is blocked, your recordings will be silent even if audio recording is enabled. This often happens after app permission resets or system updates.
Open Settings, and then tap Apps.
Tap Screen Recorder and open Permissions.
Allow Microphone access, then record a short test clip.
3. Increase Media and Recording Volume
Low volume levels can make it seem like your recording has no sound. This is especially common when system audio is recorded at a very low level.
Press the Volume Up key, and then tap the three dots to open volume controls.
Increase Media volume and Recording volume if available.
Play the recorded video again to check for sound.
4. Test With a Different App
Some apps block internal audio recording for privacy reasons. Streaming apps, banking apps, and certain games may not allow sound capture.
Open an app that allows audio playback, and then play a video or music.
Start Screen Recorder and record for a few seconds.
Check if audio is present in the recording.
5. Restart Your Phone
Temporary system glitches can interfere with audio capture. A restart refreshes audio services and fixes many recording issues.
Swipe down from the top of the screen, and then tap the Power icon.
Tap Restart and wait for the vivo S50 to reboot.
Try recording again once the phone is fully loaded.
6. Update the System Software
Outdated software can cause compatibility issues with built in features like screen recording. Keeping your phone updated helps prevent audio bugs.
Open Settings, and then tap System update.
Check for updates and install the latest version if available.
Restart the phone and test the screen recorder again.
Screen recording with audio should work smoothly once the correct settings and permissions are in place. After adjusting these options, your vivo S50 should capture both video and sound without any issues.
FAQs
Why does my screen recording have video but no sound at all?
This usually means the audio source was turned off or the microphone permission was denied. Checking both settings fixes the problem in most cases.
Can the vivo S50 record internal audio from all apps?
No. Some apps restrict internal audio recording for security and copyright reasons, so only microphone audio may be available.
Does screen recording audio work with Bluetooth earphones?
It depends on the audio source selected. If the recorder is set to system sound only, Bluetooth audio may not be captured unless microphone recording is also enabled.
