Quick fix first. Play the video outside Edits — in your camera roll or gallery — before you change anything in the project. If the exported file has sound but the Instagram post does not, the problem is at upload or playback, not in your edit. If the exported file is silent too, check the timeline: a muted clip, a volume slider turned to zero, or an audio track that was never added are the usual causes, and all three are fixed in seconds. Only if the timeline plays sound but the export does not should you work through the deeper steps below.
Missing audio is alarming because it feels like the project is broken, but in most cases the audio is still there — it is just muted, turned down, routed to the wrong output, or stripped at upload. This guide separates those cases so you fix the right one instead of re-editing a project that was fine.

The symptom, precisely
Pin down exactly where the sound disappears. Sound missing in the timeline preview but present in the original clip points to a timeline setting — mute or volume. Sound present in the timeline but missing in the export points to an export or rendering problem. Sound present in the export but missing on Instagram points to upload processing or to the viewer’s playback settings, including Instagram’s own mute behavior. Sound missing only in some clips points to those clips: they were recorded silent, muted individually, or carry an audio format Edits does not handle. Each pattern has a different fix.
Likely causes, ranked
- A muted clip or audio track. The most common cause by far: a clip was muted during editing, or an audio track’s volume was set to zero, and the setting survives export.
- Phone output problems. Silent mode, media volume at zero, or audio routed to a Bluetooth device or headphones that are not in your ears will make a perfectly good video seem silent.
- Instagram’s playback mute. Reels often start muted until the viewer taps for sound, so a video that seems silent to a viewer may simply be waiting for a tap.
- Missing or broken audio in the source clip. Some clips genuinely have no audio track — screen recordings with audio off, for example — and no setting will create sound from silence.
- Audio removed at upload. A music track that Instagram cannot license for your region or account can be muted or replaced after upload, while the exported file keeps it.
- An export or app bug. Least common, but a bad update or a corrupt cache can occasionally drop audio from an export that played fine on the timeline.
Fixes in order, quickest first
Work down this list, testing playback after each step. Stop when the sound returns.
1. Check your phone’s output first. Turn off silent mode, raise media volume, and disconnect Bluetooth devices and headphones. Play another video outside Edits: if that is silent too, the problem is your phone, not the project, and no editing change will fix it.
2. Unmute the clips and check track volumes. In Edits, tap each clip and confirm it is not muted, then check every audio track’s volume slider. The music and audio guide shows where these controls live. A single muted clip in the middle of a project is easy to miss and explains sound that cuts out partway through.
3. Check the original clips. Play each source clip in your gallery. If a clip is silent there, it was recorded that way — replace it, or add narration or music over it. Clips imported from screen recordings or messaging apps are the usual silent suspects.
4. Re-add the audio on a fresh track. If the timeline shows an audio track but nothing plays, delete that track and add the music or voiceover again. A track that was added before an app crash or a failed save can look present while carrying no audio data.
5. Export a short test and play it in your gallery. Export ten seconds and play the file outside Edits. If the test file has sound, the project is fine and the problem is in the full export or the upload — go to step 7. If the test file is silent, the problem is in the project or the app.
6. Update Edits and clear the cache. Install the latest version from the official store, and on Android clear the app cache. Then re-export the test clip. If sound returns, a bad update or corrupt cache was the cause.
7. Check the posted Reel’s playback, not just your own view. Open the posted Reel on another device or ask a friend whether they hear sound, and tap the video for sound if it starts muted. If others hear it and you do not, the problem is your playback settings, not the upload.
8. Reinstall as a last resort. Export any finished work first, and accept that on-device drafts may be lost. Reinstall only when the timeline plays sound, the test export is silent, and the earlier steps have all failed.
When audio disappears after upload
If the exported file has full audio but the posted Reel is silent or partially muted, the cause is usually Instagram’s handling of the audio, not Edits. Music tracks can be muted or replaced when Instagram cannot license them for a region or account type, and that decision is made at upload, not in your edit. The practical fix is to swap the track for one from Instagram’s own audio library, or for an original recording or voiceover, and re-upload — the advanced audio tools guide covers working with original audio. Re-exporting the same project with the same track will produce the same result, so do not repeat that step hoping for a different outcome.
Keeping audio reliable
Before a long edit, play every source clip once in your gallery and confirm it has the audio you expect — catching a silent clip at import is far cheaper than discovering it after an hour of editing. Keep one backup of the finished export in your camera roll, so a muted upload never means re-editing the project from scratch.
How to tell when it is a rollout or a server problem
Missing audio is almost always local, but occasionally a staged rollout changes how Edits handles an audio format, or a server-side change alters how uploads are processed — and then many creators lose audio at the same time without changing anything. The signs are: audio that worked last week disappears from new exports with no settings changed, other creators report the same loss at the same time, and the timeline still plays sound while every export comes out silent. When you see that pattern, check our updates page and wait for a fix rather than rebuilding projects: reinstalling and re-editing will not beat a rollout problem, and they risk your drafts for nothing.
Frequently asked questions
Why does my video have sound in Edits but not after export?
That pattern points to the export step: a track that plays on the timeline but is dropped during rendering, or an audio format the export cannot carry. Try the short test export in step 5, then update the app and clear the cache. If the test export is also silent while the timeline plays, work through the later steps rather than re-editing the timeline.
Why can I hear the audio but my viewers cannot?
Most often because the Reel starts muted for viewers until they tap for sound, or because their own device is on silent mode. Check the Reel on another device with sound on. If others hear it, the upload is fine and the silence is on the viewer’s side.
Why is only the music missing but voices still play?
That split usually means the music track itself was muted, removed, or stripped at upload, while the original clip audio survived. Check the music track’s mute and volume settings first; if the exported file keeps the music but the posted Reel does not, Instagram’s licensing handling is the likely cause, and swapping the track is the fix.
Can a Bluetooth device really make my video seem silent?
Yes — it is one of the most common false alarms. If audio is routed to earbuds in a pocket or a speaker in another room, the phone plays sound that you cannot hear. Disconnect Bluetooth and play the video on the phone speaker to rule this out before touching the project.
Should I reinstall Edits to fix missing audio?
Only as a last resort. Most missing-audio cases are a mute setting, a volume slider, or a playback problem, and reinstalling fixes none of those while risking your drafts. Reinstall after the test export and the update step have both failed — not before.

If sound is still missing after these steps, note exactly where it disappears — timeline, test export, full export, or posted Reel — because that single detail separates a project setting from an app bug from an upload problem, and it is the first thing anyone helping you will ask.
Testing audio systematically. When several tracks are involved — original clip audio, a music track, and a voiceover — test them one at a time. Mute everything except the original audio and export a short test; then unmute only the music and test again; then only the voiceover. The track that stays silent in isolation is the one carrying the problem, and the others can be left alone. This isolation test takes a few minutes and prevents the common mistake of rebuilding an entire project when only one track was at fault.
A note on voiceovers. Voiceovers recorded inside Edits depend on microphone permission, and a denied permission produces a voiceover track that looks recorded but carries no sound. If your voiceover is the only silent element, check the phone’s app permissions for Edits and re-record a short test line before re-recording the whole narration. A permission problem fixed at the start saves a second full recording session.
