Audio delay on Smart TV is usually the TV's audio processing, not the app.

 

[KevinNet]

Most Smart TVs have an audio sync offset setting. Check your TV's audio settings.

Where exactly on Samsung TVs?

Samsung: Settings > Sound > Expert Settings > Digital Output Audio Delay.

 

[BufferBuster]

Found it! Setting it to -30ms fixed my sync perfectly.

 

[CarlaStream]

LG has it under Sound > Advanced Settings > AV Sync.

LG setting helped. Had to experiment with values but -20ms was perfect for me.

If using a soundbar, the soundbar might also have its own delay setting.

 

[NickCable]

Had to adjust both the TV and the soundbar separately. Combined they're synced now.

The passthrough audio setting on some TVs bypasses processing and reduces delay.

 

[GaryStream]

Audio passthrough on Samsung removes the delay entirely on my setup.

Post-update settings reset is common. Worth saving your settings photo for reference.

The sound delay was worse after a TV firmware update. Settings reset.

Fixed with the audio delay offset. Didn't even know this setting existed.
