Some more info. I just tried the following command (test.wav is a "long" stream and click01.wav is a "short" one): aplay test.wav & aplay test.wav & aplay click01.wav & aplay click01.wav So, all playbacks start (more or less) simultaneously. test.wav wasn't blocked at all. In fact, they were playing so simultaneously that you could hardly even hear any distortion due to phase difference. The click01.wav playbacks were blocking each other, though. The first one started playing as the test.wav playbacks started. In the light of this, I guess that a "short" stream is qualified by the entire stream fitting in one playback buffer ------------------------------------------------------- This SF.net email is sponsored by: SF.net Giveback Program.
