If you're experiencing no sound while playing audio through your WiiM device, follow these troubleshooting steps to resolve the issue. 

1. Check the External Device is Powered On


Ensure that the external device (e.g., an AVR, DAC, or speaker) connected to your WiiM device is powered on.


2. Check the Power Input of Your WiiM Device


Ensure your WiiM device is properly connected to the power source using the required power adapter and cable. Insufficient power can lead to no sound issues when using analog output.


3. Check the Volume


Ensure that the volume is turned up in both the WiiM Home app and on the external device (e.g., an AVR, DAC, or speaker) connected to your WiiM device.


4. Check the Physical Connections 


Check that the physical connections between your WiiM device and the external device (e.g., an AVR, DAC, or speaker) are correctly and securely plugged in.


If you're using the Optical Out port on your WiiM device, check for a red laser light when music is playing.Don't look directly into the port! 

If no light is visible during playback, it may indicate a malfunction. In that case, please contact us or your seller for further assistance.


If you're using the Coax Out port, make sure to use the Coax cable with 75-ohm impedance. If you don't have one, you can use the provided RCA cable as a substitue.
