However, there are still short sounds that do not play (using esd). It seems that there is a delay just after opening the audio device; if the sound is too short (shorter than that delay), nothing is played. The problem with 8-bit/8KHz µ-law sounds played using the command "cat soundfile > /dev/audio" still happens. In fact, now it is worse. Just FYI. JMA -- ****** Jose M.
