With that in mind, if you want to use the sound driver then you need the following files added to your project:
23.1 Header File Contents Overview
The “Sound” module header CHAM_AVR_SOUND_DRV_V010.h has nothing in it except the prototypes for the handful of
functions. Rather, it makes more sense to show you the SPI header messages relating to the sound driver:
The above messages are located in CHAM_AVR_TWI_SPI_DRV_V010.H as well as in the main SPI driver running on
the Propeller CHAM_DEFAULT2_DRV_V112.spin or CHAM_DEFAULT1_DRV_V112.spin. The above messages only
expose rudimentary abilities of the sound driver, but they are enough to start and stop sounds, play music, sound fx, etc.
