The Xiaomi Smart Projector L1 Pro has a speaker. Under normal conditions, when the device is working properly, sound should be heard.
To resolve the issue of no sound on the Xiaomi Smart Projector L1 Pro, please refer to the following steps:
1. Please check whether the volume is set too low. Low volume will cause you not to hear any sound, so you can increase the volume;
2. Please check whether the system sound is turned off. If the system sound is muted or disabled, you can enable it in the settings;
3. Please check whether a Bluetooth speaker is connected. If the projector is connected to a Bluetooth speaker, the built-in speaker will be disabled, so you can disconnect the Bluetooth device;
4. Please check whether an external speaker is connected. When an external speaker is connected, the built-in speaker will be turned off, so you can verify and adjust the connection;
5. Please check whether the issue is caused by the playback source. A muted or silent media file will cause no sound, so you can try playing another source or app;
6. Please check whether the device needs to be restarted, reset, or updated. Resetting the projector will erase all data, accounts, documents, and installed applications. You can restart or update the device to resolve temporary issues and improve performance;
7. If the above methods do not resolve the issue, please contact the local after-sales service center.
