What is the reason for the sound lag when watching Douyin on CarPlay?

CarPlay watching Douyin sound lag is due to signal transmission issues during wireless connection between CarPlay and the phone, which is a common problem currently without a specific solution. The following is an introduction about CarPlay: 1. Introduction: CarPlay is an in-car system released by Apple Inc. in the United States, which seamlessly integrates users' iOS devices, iOS usage experience with the dashboard system. 2. Function: CarPlay seamlessly integrates users' iOS devices and iOS usage experience with the dashboard system. If a user's car is equipped with CarPlay, it can connect to devices like iPhone and use the car's built-in display and control buttons, or Siri's hands-free function to interact. Users can easily and safely make phone calls, listen to music, send and receive messages, use navigation, and more.
When experiencing audio lag with CarPlay, I've analyzed several possible causes. Bluetooth transmission delay is a primary factor, especially with wireless connections where unstable signals can cause audio to fall out of sync with video. Slow network buffering is another common issue, particularly with TikTok video streams that require stable bandwidth—network congestion can lead to stuttering. Additionally, insufficient phone performance, such as a slow processor or limited memory, may struggle to process video data in real time. Outdated CarPlay system or TikTok app versions could also contain bugs. For testing, prioritize switching to a USB wired connection to reduce latency, ensure the vehicle is in an area with strong signal reception, and update both the system and apps to their latest versions. If this occurs frequently, remember to check compatibility between your phone and the car's audio system to prevent distractions that could pose risks while driving.
