Apple Computer writes in Technical Note 19 "How to produce sound without clicking" that you can make only one call to the Sound Driver to turn it on, and then send it continuous null sound. When the application decides to make a noise, stuff the waveform in the sound buffer. After the sound has played, continue sending it null sound. I believe that the concept here is to have the sound driver running all of the time, so it dosen't click on and off. Now, in that Technical Note, Apple includes a sample program that is supposed to do this. I may have a corrupt version of the technical note, or an outdated copy, but it dosen't work. (That is from Turbo Pascal 1.0a). Rob Johnston
