Screen recording has no sound?

Your recording has picture but no audio? Work through these steps — most cases can be fixed.

Step 1: Check the audio source setting

The most common cause is choosing "Silent recording" or having the wrong audio source. Using Kuailuping as an example:

  1. Open Kuailuping and go to settings.
  2. Find the "Audio source" option.
  3. If it's currently set to "Silent recording", change it to "Internal audio" or "Microphone".
  4. Start recording again and test whether there's sound.

The three audio sources:

  • Internal audio: records the sound the phone itself plays (video audio, game sound effects) — clear and noise-free.
  • Microphone: records sound from outside the phone, including your voice and ambient noise.
  • Silent recording: records only the picture, no sound at all.

Step 2: Confirm your system version supports internal audio

If you want to record internal sound (audio from videos, games, and so on), you need Android 10.0 or above. Google only opened the internal-audio-capture API in Android 10.

To check your system version, open "Settings → About phone → Android version".

  • Android 10 and above: internal audio recording is available.
  • Android 9 and below: the system doesn't support internal audio; you can only record speaker sound with the microphone. In that case, find a quiet place, turn up the media volume, and record that way.

Step 3: Check whether the app being recorded blocks audio capture

Some apps actively block the system from recording their sound as a copyright-protection or security measure — no screen recorder can bypass this. Common examples include:

  • Some video platforms (Netflix and certain streaming apps)
  • Banking and payment apps
  • Some DRM-protected music and video content
  • Some encrypted call and meeting apps

How to tell: use the recorder on another app (such as the built-in music player or a game). If other apps have sound but a particular app doesn't, it's that app's own restriction.

Step 4: Check media volume and silent mode

This cause is easy to miss:

  • Press the volume-up button on the side of the phone and confirm the media volume (not the ring volume) is turned up.
  • Make sure the phone isn't in silent or vibrate mode. On some phones, internal audio is muted in silent mode.
  • Check that the app you're recording isn't muted itself (for example, a video player's volume slider pulled all the way down).

Step 5: Check Bluetooth devices

If the phone is connected to a Bluetooth headset, speaker, or car kit, audio may be routed to the Bluetooth device, so the recorder can't capture sound.

How to fix it:

  • Turn off Bluetooth, or disconnect the paired Bluetooth device in Bluetooth settings.
  • Confirm sound is coming from the phone's built-in speaker, then start the screen recording.

Step 6: Try restarting the app and the phone

If all the settings above are correct but there's still no sound, try:

  1. Fully close Kuailuping (swipe it away from the recent apps list) and reopen it.
  2. Restart the phone and try recording again.
  3. Confirm Kuailuping has the microphone permission (Settings → Apps → Kuailuping → Permissions → Microphone enabled).

FAQ

Why does my screen recording have picture but no sound?

Common causes include: the audio source is set to silent, the system version is below Android 10 and can't record internal audio, the app being recorded blocks audio capture, the media volume is zero, or a Bluetooth device is connected. Work through the steps in this article.

How do I record both my voice and the phone's sound?

Most Android phones only allow one audio source at a time. To record both your narration and the phone's internal sound, use microphone mode and play sound out of the phone speaker — the microphone will pick up both. The audio quality won't match pure internal audio recording.

Why do some apps record sound and others don't?

Some apps (video platforms, banking apps, DRM-protected content) actively block the system from capturing their audio output. This is an app-level copyright or security restriction that no screen recorder can bypass.

Which audio modes does Kuailuping support?

Kuailuping supports three audio sources: internal audio (records the phone's system sound, requires Android 10+), microphone (records external sound), and silent recording (video only). Switch between them with one tap in settings.
