Example dapch code does not work without changing WaveHC.h file

I received the error message "Playing HLOTEST.WAVDVOLUME must be set to non-zero in WaveHC.h" I had to go into the WaveHC.h file and change the #define DVOLUME 0 to #define DVOLUME 1

Start by reproducing the example's error and inspect the example together with WaveHC.h, especially the DVOLUME definition. Confirm whether the example should work without manually changing that header; done means the example plays successfully with the default configuration.
