 Play a .wav file.
int wav_playing ()

void wav_volume (int vol)
 Set wav play volume 0 to 10. 0 is lowest, 10 is highest.
void wav_stop (void)
 Stop wav file reading but leave audio output open so that you can play another track without a click at the start. Recommended over wav_close unless your application needs to recover both the wav reading and audio output cogs for other uses.
void wav_close (void)
 Stop wav file reading and close audio output. Only recommended if your application needs to recover two cogs for other purposes. Otherwise, use wave_stop. It will stop the cog that reads the wav file, but leave the audio output cog open, which will prevent a click at the start of the next track your application plays.
