Why is there a sound delay when the Xiaomi Desktop Speaker Pro Set connects to devices via AUX IN port?

Question

Accepted Answer

If there is a sound delay when the Xiaomi Desktop Speaker Pro Set connects to devices via the AUX IN port, please refer to the following reasons:
1. Although AUX transmits analog audio, the speaker converts the signal into digital internally for functions such as crossover processing with the subwoofer, which can cause a small delay before playback.
2. Some devices or Apps apply additional processing before sending audio to the speaker, such as sound enhancement or spatial audio effect, which can add extra latency, especially in video playback or real-time audio Apps.
3. The environmental or signal interference, including nearby Wi-Fi devices, Bluetooth signals, or certain hardware configurations, can also affect processing or playback stability.
