  What exactly do you mean by "activate"?

  When I connect my phono amp to the analogue input of the card and the RPi is running on Raspberry Pi OS, I can’t here any sound from the analogue output. Do I need to set up any in order to use the card under RPi OS?

  I can only here sound from the analogue output when running the songs in the RPi

  The the normal behavior. The input can be recorded, but it's not routed on the output. To do this, you need to use a tool that can read from the input and play back data on the output. 

  A simple tool that can do this is "alsaloop" Make sure, you read the manual page to use the correct command line parameters.
