Subtitle delay is usually a sync problem between the video, audio, and caption track. It is common in streaming apps, live TV, DVR playback, soundbars, and Bluetooth headphone setups.
These steps apply to subtitles and closed captions in apps such as Netflix, Prime Video, Hulu, Disney+, cable boxes, DVRs, antennas, and smart TVs.
Does this affect you?
Use this if captions appear before or after dialogue, drift farther out of sync as a show plays, or behave badly in one app while other apps look normal.
Restart the app or stream
- Stop playback and back out of the title.
- Return to the app’s home screen.
- Fully close the app instead of only backing out.
- Reopen the app and resume the same episode or movie.
- Turn subtitles off and back on inside the playback controls.
When subtitles begin in sync and slowly drift, the app often needs to re-fetch the subtitle track and line it up again.
Adjust audio/video sync settings
Use this when subtitles are delayed and the spoken audio also seems ahead of or behind mouth movement.
- Open your TV’s sound settings.
- On Samsung, look under Settings > Sound > Expert Settings.
- On LG, look under Settings > All Settings > Sound > AV Sync Adjustment.
- On other TVs, look for AV Sync, Audio Delay, or Lip Sync.
- Adjust the delay in small steps while watching a scene with clear speech.
- Stop when the audio lines up with the speaker’s mouth movements.
Subtitles are usually timed to the audio track, so fixing the audio/video sync can also make captions feel correct. This is especially useful with soundbars, receivers, and other external audio gear.
Fix live TV or DVR subtitle delay
- If you use a cable box, satellite receiver, or DVR, unplug that box for 30 seconds and restart it.
- Compare live playback with recorded playback.
- If only one recording is out of sync, delete and re-record the show if possible.
- On the TV, toggle captions off and back on under Settings > Accessibility > Closed Captions.
- For antenna channels, check signal strength if caption delay happens only on over-the-air TV.
Live TV captions are decoded by the box, DVR, or broadcast path, so restarting the TV alone may not fix them.
Updates, bad subtitle files, and Bluetooth lag
If only one movie or episode has bad timing, the subtitle file may have been encoded incorrectly by the streaming service. Report the title through the app’s help or report feature.
Update the affected app from your TV or streaming device app store. Streaming services regularly fix subtitle timing bugs through app updates.
Bluetooth headphones can add audio delay, making subtitles feel wrong even when the caption track is fine. Check the TV or headphone settings for low-latency, game mode, or reduced-delay audio options.
