How to program STEVAL-MKBOXPRO's audio buzzer?

In the getting started guide there is a programmable audio buzzer names SPK1 but I can't find reference of it anywhere, where I can enable it in the .ioc file and how to interact with it? Please could someone advise me on this.

Have you tried looking at the schematics?

 

As always, they's on the 'CAD Resources' tab of the Product Page:

A complex system that works is invariably found to have evolved from a simple system that worked.A complex system designed from scratch never works and cannot be patched up to make it work.
