What Causes The TCL TV Lip Sync Problem?

Your TCL Android TV audio is out of sync due to various reasons, including the following: 

1. Audio Process Delay

In some cases, the TV’s audio processing gets delayed. This delay causes a conflict between the audio and video of the displayed content, resulting in the Lip sync problem. It might be due to the TV’s internal audio settings.

Using any source device, such as A cable box, Blu-ray player, or Gaming console, can cause a Lip sync problem. 

Any delay in the audio signal from the source device results in TCL Roku TV lip sync issues. The delay might be due to incorrect settings or insufficient processing speed. 

3. HDMI CEC Problem

HDMI CEC (Consumer Electronic Control) is a feature in smart TVs that secures the HDMI connection and communication among devices. Sometimes the weak connection between the TV and the source devices leads to audio and sound-related TCL TV common problems.  

4. Incorrect Settings

Wrong audio or video settings on the TCL TV are also a reason for the Lip sync issue on your TCL TV. For instance, Incompatible or incorrect audio output settings can cause synchronization issues.

5. Streaming Apps 

Multiple streaming apps can also cause out-of-sync audio and video problems. Streaming apps cause issues due to network latency, encoding or decoding delays, and incorrect audio or video settings.
