Hey I just tried out the sound examples on my old P200 and they don't work either. The sound seems to stutter. What I think is happening is its not waiting the correct time before the callback function is activated. Damn shame. I was hoping SDL would be useful. Just tries it on the 1.5 Ghz Win 2000 machine and I get the same noise. Not Happy! Edited by - Davaris on December 11, 2001 1:07:38 AM
