The Xiaomi Soundbar 2.0ch is designed to enter standby mode automatically when there is no audio signal input for a certain period. This is a normal energy-saving feature and not a malfunction.
If the soundbar automatically turns off after not being used for a period of time, please refer to the following steps:
1. Ensure that the device connected to the soundbar is actively playing audio. Paused or muted playback can cause the soundbar to detect no signal and power down;
2. For Bluetooth connections, make sure the paired device remains connected and within range. Inactivity or disconnection can trigger auto-shutdown;
3. When using with a TV or computer, enabling background audio (such as sound effects or menu sounds) can help maintain activity and prevent auto standby.
