Why LinkedIn Videos Have No Sound When Downloaded & How to Fix It
An exhaustive diagnostic guide to troubleshooting missing, muted, or copyright-silenced audio in downloaded LinkedIn MP4 files.
If a downloaded LinkedIn video has no sound, the issue is typically caused by: 1. A copyright licensing takedown by music labels (e.g. UMG/Warner) muting the audio globally or regionally. 2. Device hardware volume or silent switch enabled on iOS/Android. 3. Video player codec mismatch with AAC audio streams. 4. Content creator uploading without mic input. Use LinkedNL to download synchronized 1080p MP4 with preserved audio or extract standalone 320kbps MP3.
Test LinkedNL with Your LinkedIn Link
Paste any public LinkedIn video or lnkd.in link to extract clean HD MP4 or MP3 directly to your device.
The 5 Root Causes Why LinkedIn Videos Download Without Sound
Encountering a downloaded LinkedIn video that plays silently is a frequent frustration for creators and archivers. This issue is almost never random—it stems from one of five distinct technical or licensing mechanisms:
- 1Copyright Music Takedowns: Music labels (such as Universal Music Group, Warner, or Sony) regularly issue copyright strikes that mute the audio track across the LinkedIn platform.
- 2Audio Codec Incompatibility: The video's audio track is encoded in an advanced format (e.g. AAC-LC or Opus) that your default media player cannot decode.
- 3Device Silent Mode & Muting: iOS Silent switch or Android media volume set to zero.
- 4Commercial Audio Licensing Restrictions: Commercial business accounts using non-cleared songs.
- 5Corrupted Download Stream: An interrupted network connection during file transfer causing a missing audio container atom (

Original Sound vs Added Music
If a LinkedIn video's background music was removed by LinkedIn for copyright, the entire audio stream is silenced on ByteDance's servers, including voiceovers mixed into the same track.
Copyright Takedowns & Commercial Music Licensing
LinkedIn operates under complex licensing agreements with global music publishers. When a licensing dispute occurs (such as the high-profile catalog removal by major labels), LinkedIn runs automated algorithms that silence millions of videos utilizing those commercial sound recordings.
When this occurs, the master video file on LinkedIn's CDN is updated with a blank audio stream. If you download a video that has already been silenced by LinkedIn, the resulting MP4 will contain no audio data because no audio exists on the source server.
Audio Codec Incompatibilities (AAC vs MP3 vs Opus)
LinkedIn encodes audio using Advanced Audio Coding (AAC) within an MP4 container. While modern smartphones natively decode AAC, older Windows media players (such as Windows Media Player legacy) or Linux video players may lack proper codec filters:
- Supported Codec: AAC-LC (Low Complexity) stereo at 44.1 kHz / 48 kHz
- Bitrate: 128 kbps to 320 kbps variable
- Container Format: ISO Base Media File Format (MPEG-4 Part 14)
If your computer plays the video without sound while your phone plays it with sound, the issue is your computer's media player codec pack. We recommend using VLC Media Player to play any MP4 file seamlessly.
Device Audio Settings Diagnostic Checklist
Before assuming the download is broken, verify these device-level audio settings:
| Platform | Potential Audio Conflict | Quick Diagnostic Fix |
|---|---|---|
| iPhone / iPad | Hardware Silent Switch / Focus Mode | Flip the physical switch on the left side or check Action Button / Control Center. |
| Android | Separate Media Volume Slider | Press Volume Up > tap the three dots (...) > raise the Media volume slider. |
| Bluetooth Devices | Audio routed to disconnected headphones | Turn off Bluetooth or disconnect wireless earbuds in Control Center. |
| Windows PC | Muted browser / application volume mixer | Right-click speaker icon > Open Volume Mixer > unmute the media player. |
| Mac (macOS) | Output device set to external monitor | Open System Settings > Sound > select MacBook Built-in Speakers. |
How LinkedNL Preserves Audio & Extracts 320kbps MP3s
LinkedNL analyzes the audio and video streams separately on the CDN. When you download through LinkedNL:
- Multiplexed HD MP4: We ensure the H.264 video track and AAC audio track are properly multiplexed with synchronized presentation timestamps (
PTS). - Dedicated MP3 Audio Extraction: If you only need the sound or voiceover, our audio engine extracts the pure audio bitstream and converts it into a high-fidelity 320kbps MP3 file suitable for any device or editor.
Step-by-Step Fixes for Silent LinkedIn Downloads
Follow this sequential workflow to fix sound issues:
- 1Test the Video in the LinkedIn App: Play the video inside the official LinkedIn app. If it is silent there, the creator uploaded it without audio or LinkedIn removed the sound due to copyright.
- 2Re-download Using LinkedNL: Paste the link into linkednl.com and select the "Download Without Watermark (HD)" option.
- 3Try the MP3 Download Option: If the video player has codec issues, download the "MP3 Audio" track to verify if the audio stream is intact.
- 4Play with VLC Media Player: Open the downloaded MP4 in VLC (available free for Windows, Mac, iOS, and Android) to bypass system codec limitations.
Frequently Asked Questions
Q.Why is my downloaded LinkedIn video muted?
The most common reasons are: 1. LinkedIn muted the sound due to copyright licensing issues. 2. Your device is on silent mode or the media volume is low. 3. Your media player does not support the AAC audio codec.
Q.Can LinkedNL recover sound from a video muted by LinkedIn for copyright?
No download service can recover sound if LinkedIn has permanently muted the audio on their servers, as the master file itself has had the audio track removed.
Q.How do I download just the audio track or voiceover from LinkedIn?
Paste the video link on linkednl.com and click the "MP3 Audio" button. You will get a high-quality 320kbps MP3 file containing only the audio track.
Q.Why does the downloaded video have sound on my phone but not on my PC?
This happens when your PC's media player lacks AAC audio decoders. Installing the free VLC Media Player will resolve the issue immediately.
Q.Can I use downloaded LinkedIn audio in my own videos?
You can use audio for personal editing, but ensure you comply with copyright and licensing regulations if you plan to publish or monetize your content.
