How to activate coax input

I just got my Khadas Tone1 board. When connected to a PC the DAC works as expected. Now I want to connect a CD player as well. But I am not able to get sound out the board. To make sure nothing gets sent over USB I have also connected the board just to a charge - but same result no audio. The same CD player connected to another DAC works fine.

What can I do here ?


  • You can try to connect to PC,and play a music by any app,then stop it,the Tone1 can change the input source from USB to coaxial input.

  • You can also take a high defintion photo of your connection.
