No sound usually means an unsupported audio codec, a muted track, or a player that cannot decode the audio. Re-encode audio to AAC in an MP4, or check the source has audio.
Common Causes
- Unsupported audio codec: the player cannot decode the audio (e.g., Opus in MP4).
- No audio track: the source video is silent.
- Muted or low volume: the clip was recorded muted.
- Wrong output settings: audio was not selected during conversion.
How to Fix It
Use a compatible audio codec
Convert to MP4 with AAC audio, the most widely supported combination (H.264 + AAC).
Verify the source has sound
Play the original video. If it is silent there, the problem is the recording, not the conversion.
Re-convert with audio enabled
Open a tool like MOV to MP4 or WebM to MP4 and ensure audio is included.
Troubleshooting by Scenario
| Scenario | Fix |
|---|---|

| Original is silent | Re-record or restore source |
Because Easy Converter processes files in your browser, audio handling depends on the chosen codec settings.
