Audio delay, missing sound, unavailable subtitles, and synchronization problems can come from the title, player, television, soundbar, or device settings. Follow this TereaTV checklist from the simplest test to the more specific fixes.
Identify whether the issue affects one title or everything
Open two or three different items. If only one channel, film, or episode has the issue, record its exact name and time. If every item is affected, focus on the device, player, HDMI path, Bluetooth connection, television, or sound system.
When there is picture but no sound
- Confirm the television and player are not muted.
- Raise the volume on both the streaming device and television.
- Disconnect Bluetooth headphones or speakers temporarily.
- Restart the player and streaming device.
- Change the player audio output to a widely supported format such as stereo or PCM for testing.
- Test without the soundbar or receiver if practical.
Fixing audio that is ahead of or behind the picture
First pause and resume the title, then change away and return. Restart the device if the delay remains. Disable optional motion smoothing or audio-processing features temporarily. Soundbars and receivers may provide an audio-delay setting; return extreme custom values to their default before testing.
Check the audio track
Some on-demand titles include several languages or codecs. Open the player’s audio-track menu and select the required language. If one track is silent, test another available track and note the result for support.
When subtitles do not appear
- Confirm that the selected title actually offers subtitles.
- Open the subtitle menu after playback begins.
- Select a language explicitly instead of leaving the setting on Auto.
- Increase subtitle size or contrast if text is present but difficult to read.
- Restart the title after changing the track.
Subtitles are early or late
If the player offers subtitle-delay controls, adjust in small steps and retest the same scene. Do not apply a large permanent offset based on one title because another title may already be synchronized correctly.
Clear cache only after the basic tests
A damaged temporary file can affect playback behavior. Close the player, clear only its cache where the device provides that option, then reopen it. Avoid clearing app data unless you have the official login details available, because clearing data can sign the account out.
What to send TereaTV support
- Device and model.
- Player name and version.
- Title, channel, season, or episode.
- Selected audio and subtitle language.
- Whether the issue also appears on another device.
- A short description of the delay or error without exposing credentials.
For broader playback problems, use the TereaTV buffering guide. For platform preparation, review the supported-device checklist. Contact official TereaTV support when the same reproducible issue remains.
