Did you use NIOS II for alarm clock or direct HW?

I think you need to use NIOS II and right drivers to initialize and use CODEC chip.

Easiest way is to get Piezo buzzer and control it with selected GPIO.

If you want to use IO pin to audio output for amplifier then this may help. Examples are in Verilog.

Edit:

GPIO (General Purpose Input Output). Usually mean pin in FPGA.
