Why does my video play with no sound on LinkedIn? What to check
Unmute the LinkedIn player and check device volume, then compare with the local original. If sound returns, the player was muted. If it stays silent, inspect the source or export; autoplay does not prove the audio track is intact.
Check these first
- Whether the video has sound when opened directly (tap to unmute) rather than assuming the file is silent
Likely causes
- The player may be muted
Try unmuting the player and checking device volume. If the original is also silent, investigate the audio track or export; autoplay behavior cannot prove the track is intact.
Fix it
- Design for sound-off viewing
Captions can make the opening understandable when sound is off. This does not establish how many viewers use muted playback.
