No sound at the headphone output with audio board

[Cordel]

Hello,

I have searched and tried a lot but I have a problem with the audio board and Teensy 4.0.
I Have no sound coming from the headphone.
I have set every thins like the tutorial and the part_1_02_Hardware_Test is correctly loaded on the teensy
the 3 buttons respond well on the serial port
the 2 pot too
and the volume pot is good too
but I should hear the beep with the headphone connected but no.
I did try several different headphones with no succes.

I can't send a photo of the installation.

I haven't solved the problem but I've found an alternative by sending the sound to audacity, which is sufficient for my project.

@Cordel: Here are the initialization calls that I have used in a short test sketch, written to test the modulated/tunable strings audio object that @h4yn0nnym0u5e created for our use:

   sgtl5000_1.enable();
   sgtl5000_1.muteLineout();
   sgtl5000_1.dacVolume(1.0f);
   sgtl5000_1.unmuteLineout();
   sgtl5000_1.adcHighPassFilterDisable();
   sgtl5000_1.volume(0.5f);

I don't think that any part of it is particularly specific to enabling the headphone output, but hope that it helps in some way . . .
