Why does my video play with no sound on X? What to check
Unmute the X player and check device volume, then compare with the local original. Playback settings vary. If the original has sound but the uploaded version does not, inspect processing or export settings instead of assuming muted autoplay.
Check these first
- Whether the video has sound when tapped to unmute
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.
