Hello, I can't get the dac2pro to work on my pi5. I'm a newbie... I understood that it was necessary to add the line dtoverlay=hifiberry-dacplus in the config.txt file, but where exactly? I've searched everywhere on forums or tutorials, sometimes it requires removing lines, other times a #, but I can't get it to work. By default the dac2pro green LED is on, but no sound comes out. And as soon as I touch config.txt, led turns off, no sound either. Any idea?

  If the LED is on, the driver is loaded already. You can try without any config in config.txt if you're already using the latest Linux kernel.
  What's the output of the command

  aplay -l

  Here is the config.txt. Do you see a problem ?

  I'm sorry, I don't understand which information you want, my English is not the best and I'm a newbie... Could you please explain?

  Ok. You're probably still using an older kernel. First let's try updating the kernel to the latest version that has a better sound cards detection integrated
  
  Run
  rpi-update
  
  When it has been finished, reboot
