  "Insert a buffer's worth of sound samples into the currently playing  
  buffer. Used to make a sound start playing as quickly as possible. The  
  new sound is mixed with the previously buffered sampled."
  "Details: Unlike primitiveSoundPlaySamples, this primitive always starts  
  with the first sample the given sample buffer. Its third argument  
  specifies the number of samples past the estimated sound output buffer  
  position the inserted sound should start. If successful, it returns the  
  number of samples inserted."
