How to Fix OneDrive Videos Having No Sound in a Web Browser
Question details
Users experience silent playback when watching MP4 or MKV videos uploaded to OneDrive via a web browser, despite the files having sound locally.
- Product
- OneDrive
- Device & OS
- Mac
- Scenario
- Playing recently uploaded video files directly from OneDrive in a web browser.
- Observed behavior
- The videos play normally with sound locally on a Mac, but have no audio when streamed through the OneDrive web player.
Before troubleshooting, ensure your Mac's system volume is turned up and test the video on your local drive to verify the original file contains an active audio track.
Check Browser Player Settings and Volume Mixer
Ensure the web player isn't muted and the browser has permission to play sound.
Often, the simplest solution is checking if the media player or browser itself has been muted. Web browsers can sometimes block auto-playing audio.
Look at the built-in volume icon at the bottom right of the OneDrive video player frame to ensure it is not muted or set too low.
Open your Mac's sound settings or the volume mixer to confirm the web browser is allowed to play sound and is not muted.
Open the video in a different supported browser (like Safari, Chrome, or Edge) to rule out browser-specific audio blocks.
Clear Browser Cache and Cookies
Corrupted browser data can interfere with media playback and streaming services.
Verify Video Encoding and OneDrive Processing Status
Some newer formats or codecs might not be fully processed or supported by the OneDrive web player.
Seamlessly Manage Your Files with WPS Office
While troubleshooting OneDrive media issues, consider switching to WPS Office for your document needs. It's a free, lightweight, and highly compatible Office alternative that includes its own cloud storage for easy file management.
- 1. Download and Install WPS Office: Visit the official WPS website and download the free version for your Mac or PC.
- 2. Sign In to Access Cloud: Create a free account to activate your WPS Cloud storage for easy cross-device file syncing.
- 3. Open and Edit Microsoft Formats: Drag and drop your existing Word, Excel, or PowerPoint files directly into WPS Office to continue working seamlessly.
Frequently Asked Questions
Why do MKV files often have no sound in the OneDrive web player?
MKV is a container format that frequently uses audio codecs like AC3 or DTS. Many web browsers do not natively support these codecs for playback, resulting in silent videos. Converting the audio track to AAC usually resolves this.
Can I download the video from OneDrive to play it with sound?
Yes, downloading the file directly to your Mac or PC and playing it with a local media player (like QuickTime or VLC) bypasses browser limitations and will play the audio normally.
Does OneDrive remove the audio track during the upload process?
No, OneDrive does not remove the audio track when you upload a file. However, the web player might serve a compressed preview version while processing, which can temporarily lack sound or quality until fully processed.
