Samsung TV & Audio HW-S800B Ultra Slim 3.0 Channel 360 Watt Soundbar with Dolby Atmos and Bluetooth LIP SYNC Error Fix: Audio Out of Sync with Video (Lip Sync Delay)

Error code LIP SYNC on the Samsung TV & Audio HW-S800B Ultra Slim 3.0 Channel 360 Watt Soundbar with Dolby Atmos and Bluetooth means: Audio Out of Sync with Video (Lip Sync Delay). Audio is noticeably ahead of or behind the video — most common Samsung soundbar audio complaint. Causes and fixes by connection type: HDMI ARC — adjust audio delay on TV: Settings → Sound → Expert Settings → Digital Output Audio Delay → adjust in 20ms increments. Also try soundbar's own audio sync setting via remote or SmartThings. Bluetooth — inherent 100-300ms latency is unavoidable; switch to HDMI ARC or optical for video content. Optical — set TV audio format to PCM (least processing delay). Streaming apps — often have their own processing delay; check app-specific audio sync settings. Game mode on TV reduces input lag and can help sync. eARC has lower latency than standard ARC.
