Alarm won’t sound

Difficult to answer with so little info.

For example do none of the alarm functions work when alarm switch is set to activate the alarm (ie Radio or Alarm)?

You also do not mention if it has a mechanical or digital mode-switch and if it worked in the past and has now stopped working.

If it did work previously and now no longer does, then suspect the mechanical switch or wiring/printed circuit board track.

It goes without saying that the switch needs to be set to one of the above choices (Radio or Alarm and if set to Alarm, then either to Music [Radio] or Buzzer).

If this is a new radio being set up, especially the digital kind with multi-function press switches, this can be tricky when trying to follow sometimes unclear instructions.
