No sound when you turn on your TV box? This is most likely a settings or connection issue. Follow these steps to easily turn on the sound.
I. Check Hardware Connections
Make sure the audio cable is plugged in securely.
Whether it’s an AV cable, HDMI cable, or SPDIF cable, unplug it and plug it back in firmly.Test with another device.
Connect the audio cable to another device (e.g., your phone to speakers) to rule out the possibility of a damaged cable.
II. Troubleshoot TV Box System Settings
2.1 Open Settings
Find the 【Settings】 icon on the main screen of the box and click to enter the settings page.
2.2 Enter Sound Settings
On the settings page, click to enter the 【Sound & display】 interface.
2.3 Check Audio Output Mode
Select 【Audio output】 and confirm that the currently selected output method matches the actual connected interface:
● Connect to TV with HDMI cable → Select “HDMI”
● Connect speakers with SPDIF cable → Select “SPDIF”
● Connect to speakers with AV cable → Select “AV”
III. Other General Solutions
● Restart Devices
