| Symptoms. | Possible cause | Decision |
|---|---|---|
| The sound is interrupted at high volume. | Overload of built-in speakers or power limitation in firmware | Turn down the volume to 80% or connect external speakers |
| Wheezing and interference during reproduction | Poor quality of source audio or codec failure | Check the file on another device or update the firmware |
| Sound and image are not synchronized | Delayed audio processing (especially when connected via Bluetooth) | In the sound settings, enable Lipsinchronization or reduce latency manually |
| Silent sound in some applications | Limitations DRM or settings of audio output in the application | In the app settings (e.g. Netflix), select Stereo instead of 5.1. |
