CapCut No Sound? How to Fix Audio in Preview and Export

First, figure out where the sound is missing

Before changing anything, take ten seconds to pin down the symptom. It saves you from chasing the wrong fix.

• No sound in the preview while editing. You press play inside CapCut and hear nothing. This is almost always a volume, mute, or audio-device issue on your own computer or in the project.
• Sound in the preview, but the export is silent. Editing sounds fine, but the finished MP4 has no audio when you play it elsewhere. This points to a track being muted at export, a codec the player can't read, or a snag during rendering.
• No sound anywhere, including imported clips. A clip that should have audio shows a flat, empty waveform. The file itself may use an audio format CapCut couldn't read on import.
• Sound plays, but at the wrong moment. That is a sync problem rather than missing audio; see CapCut audio out of sync for those fixes.

Fix no sound in the CapCut preview

If you can't hear anything while editing, run these checks in order. Most people find the cause in the first two.

1. Check your computer's volume and output. Make sure your system isn't muted and the volume is up. On Windows, click the speaker icon in the taskbar and confirm the correct output device (your speakers or headphones) is selected. On Mac, check System Settings > Sound > Output. If you plugged in or unplugged headphones while CapCut was open, this is often the whole story.
2. Check the master volume inside CapCut. Look at the preview window for a speaker or volume icon, usually near the playback controls. If it's muted, click to unmute it. It's easy to bump this by accident.
3. Look for a muted track on the timeline. Each audio and video track has its own mute toggle (a small speaker icon on the track header). If a track is muted, its clips play silently. Click the icon to turn sound back on for that track.
4. Check the volume on the individual clip. Select the audio or video clip, open the Audio tab in the panel, and make sure the Volume slider isn't dragged down to zero. A clip set to 0% is silent even when everything else is fine.
5. Confirm the clip actually has audio. Some screen recordings and downloaded files have no audio track at all. If the clip shows a flat line where the waveform should be, there's simply nothing to play.

Fix audio missing from the exported video

This is the more confusing version: it sounds right inside CapCut, but the file you saved is silent. Here's the capcut audio missing export checklist.

1. Make sure no track was muted at export. A muted track plays silently and exports silently. Before you export, scan every track header on the timeline and confirm none of the speaker icons are switched off.
2. Check where you're playing the exported file. Try the video in a different player, like VLC, or upload it to its destination (the platform you made it for). Some basic players or older media apps struggle with the audio codec CapCut uses, so the sound is there but your player won't decode it.
3. Re-export as a standard MP4. In the export dialog, choose MP4 as the format if it isn't already. MP4 is the most widely compatible container and the safest choice for audio that plays everywhere.
4. Lower the export settings and try again. Occasionally a very high frame rate or bitrate setting causes a hiccup during rendering. Drop to 1080p, 30fps and export once more to see if the audio returns.
5. Re-add the audio and export fresh. If a single imported clip's sound is missing from the export, remove that clip's audio from the timeline, re-import the original file, drop it back in, and export again. This rebuilds the audio data and clears most one-off glitches.

If your export troubles go beyond sound and the picture is also coming out soft or pixelated, our guide on fixing a blurry or low quality CapCut export walks through the right resolution and bitrate settings.

When an imported file's audio won't play (codec issues)

Sometimes the trouble starts the moment you drag a file in. The clip appears, but its waveform is flat and there's no capcut no audio to be found, in preview or export. This usually means the file's audio is in a format CapCut couldn't read.

Most everyday videos use widely supported audio like AAC, and those import without a hitch. But files from certain cameras, screen recorders, or unusual downloads can use a codec CapCut doesn't decode, so it brings in the video and leaves the audio behind.

The reliable fix is to convert the file before importing:

• Run the original file through a free converter (a tool like HandBrake works well) and export it as an MP4 with AAC audio.
• Import that converted copy into CapCut. The waveform should now appear, and the sound will play in both the preview and the export.

Update CapCut (and restart it)

If the checks above didn't land, the app itself may be the issue. Audio bugs do crop up in specific versions and get patched quickly, so running the current build matters.

1. Restart CapCut first. Close it completely, then reopen your project. A fresh start clears temporary audio glitches more often than you'd expect, including cases where CapCut latched onto the wrong output device.
2. Update to the latest version. Open CapCut and look for an update prompt, or head to the official site at capcut.com and download the current desktop version over your existing install. Newer builds fix known capcut sound not working reports.
3. Reboot your computer if sound is broken system-wide. If nothing on your PC or Mac has sound, a full restart reloads your audio drivers, which often fixes the underlying problem.

Always download updates from capcut.com rather than a third-party site. If a fresh install gives you trouble, our walkthrough for when CapCut won't install on Windows covers the common roadblocks.

Still no sound? A few last things to check

If you've worked through everything and CapCut is still silent, these less common causes are worth ruling out.

• Audio drivers are outdated or disabled. On Windows, open Device Manager, expand Sound, video and game controllers, right-click your audio device, and choose Update driver. A driver issue can mute every app, not just CapCut.
• The app's permissions are limited. On Mac, audio output rarely needs permission, but if you're recording a voiceover and nothing is captured, check System Settings > Privacy & Security > Microphone and make sure CapCut is allowed. On Windows, the matching switch is Let desktop apps access your microphone; our guide to recording a voiceover in CapCut on PC covers both systems.
• A second audio app is grabbing the output. Conferencing and streaming tools sometimes take exclusive control of your sound device. Close apps like Zoom, Discord, or OBS, then reopen CapCut.
• The export finished with an error. If the render didn't complete cleanly, the file can be missing its audio. Export again and let it run all the way to 100% without interrupting it.

While you're updating drivers, if you also see graphics warnings when you launch the app, our guide on the CapCut GPU and graphics driver error can help you clear those at the same time.
