Product: Microsoft OneDrive and Stream
Device & OS: not provided
Scenario: Uploading a video file to cloud storage or streaming platforms for sharing and online playback.

Solution 1Recommended

Convert the Video File to MP4 Format

Converting your video to an MP4 format with a standard AAC audio codec ensures full playback compatibility across Microsoft's cloud web players.

Cloud platforms like OneDrive and Stream rely on standard web-based HTML5 players. If your original video uses a proprietary or uncommon audio codec, it may play fine on desktop media players (which have the necessary decoders) but will fail to produce sound online.

Open a video converter

Launch a trusted video conversion application on your computer or open a reliable online video converter tool in your browser.

Import the video

Upload or drag-and-drop the video file that is experiencing the audio loss into the conversion software.

Select standard output settings

Set the output video format to 'MP4' and verify in the advanced settings that the audio codec is set specifically to 'AAC'.

Export and re-upload

Start the conversion process. Once finished, upload the newly converted MP4 file to your OneDrive or Stream account and test the playback.

Optimal Formats: For the best web playback experience on OneDrive and Office.com, Microsoft strongly recommends using the MP4 video format paired with the H.264 video codec and AAC audio codec.

Frequently Asked Questions

Why does my video have sound on my computer but not on OneDrive?

Desktop media players, like Windows Media Player or VLC, use local decoders that support a wide variety of audio formats. OneDrive's web player is more limited and relies on browser-supported codecs. If your video uses an unsupported audio codec, the web player will only play the visual track.

Can I fix the OneDrive video sound issue without converting the file?

If you share the file as-is, the recipient can download the video directly to their local device instead of playing it in the browser. Once downloaded, it should play normally with sound on their local desktop media player.

Which video formats does OneDrive officially support for web playback?

OneDrive supports most common video formats including MP4, MOV, and M4V. However, ensuring the file uses the H.264 video codec and AAC audio codec is crucial for guaranteed visual and audio playback on the web.
