Find where the delay starts
Check whether the issue occurs in every app or only one source. Test TV speakers without the soundbar and compare live content with a local video file. Treat iptv audio sync probleem as a topic to investigate, not as proof of the commercial claims behind an offer.
For lip-sync issues, test the player audio delay first, then the TV or soundbar settings. Change one setting at a time.
Review audio settings
A TV, soundbar or receiver may process digital audio with a delay. Look for audio delay, passthrough and lip-sync options in device settings.
Update software
Check firmware on the TV and soundbar and the player version. Restart devices after changing settings.
Report source-specific issues
If the issue occurs only with one programme, record the title and time and report it to the source provider.
Checklist before you continue
Connect audio directly to the TV first to identify whether delay comes from a soundbar, Bluetooth connection or player setting.
