DAC+ DSP LED behaviour

I am creating something with an external I2S device and this works great so far.

I am trying to get a signal out when something is playing back, be it the raspberry or the I2S device and thought it should be doable with the DSP and as far as I can see it is working with the LED out of the box. If I play something back from the Raspberry it does light up. If I play something back from an external I2S device it does not.

I can not really identify the reason for that in the DSP program.

Any ideas?

Thank you all beforehand!

  In our profiles the LED simply show the state of the "MUTE" block.

  Hey there
  
  I have seen it and managed to create a signal detection with the LED as GPIO out in order to test it.
  

  I used the "4way-iir-delay-mixer" as a base as I read this is the project used out of the box.
  
  the problem now is as soon as I download the project the output from the Raspberry is nearly silent and the second I2S input does not work at all.
  The second input as well as the first both are detected by the signal detection circuit, therefore i think something is working correctly .

  I did not manipulate any other settings.
  
  I even downloaded the project again and uploaded it but the problem persists.
  
  Are there any things changed regarding the project that was initially on the board?
  
  Thank you very much for the assistance :)

  Nvm. the old version of the "4way iir delay mixer" behaves as expected and does not show any of the unwanted behaviours I described above. Only the newer version does it.
