Check your supply. Measured at input, do you have the 5.5v ?

If it is playing music file than it is probably just a bad LED. Do you have another one you could try?

i already wrote that there is no sound.
and when i stop the music or even disconnect the input the mute led doesn`t light up.
just the lock led turns off.

Hi Back,

Did you double check the led's orientation? It is a bit fuzzy on the picture but it seems to be in wrong orientation!

Good luck,
Milton
