Your audio is out of sync with the video while streaming
Audio sync problems are caused by a Bluetooth speaker or soundbar adding a slight delay. Bluetooth audio has built-in latency. Use HDMI ARC/eARC or optical for a soundbar instead, or enable the TV's audio delay compensation setting.
Audio/video sync (lip sync) problems happen when audio takes a different route or processing time than video. Bluetooth audio has a built-in delay of 40-300ms for the codec. Modern TVs' picture processing also adds delay. When audio arrives before the processed picture, you get out-of-sync audio.
