If the Mi Smart Projector sound effect is abnormal, please refer to the following troubleshooting steps:
1. Ensure that the volume level on the projector and the audio source is not set too high, as this can cause distortion or abnormal sound effects;
2. Test the projector with a different audio source (e.g., a different device or audio file) to see if the issue is specific to one source;
3. Access the projector's audio settings and adjust them to see if it improves the sound quality. You can try resetting the audio settings to their default values;
4. Ensure that your projector has the latest software updates installed by going to [Settings] >> [Device Preferences] >> [About] >> [System update] and check for updates;
5. Nearby electronic devices or strong light sources can interfere with the projector's audio quality. Try moving these devices away from the projector or blocking out excess light;
6. If the issue persists, you can try resetting the projector to its factory settings. This will erase all settings and data, so back up any important information before proceeding;
7. If the above troubleshooting methods still can’t resolve the issue, please contact our local official service center or your seller for further assistance. They will help you in this regard.
