Well, in order to settle the matter, the wav file is available at http://maleelma.free.fr/lemmel/test.wav.bz2, and this is my software and hardware configuration : - amarok 1.4.1-3 - xmms 1.2.10+20060901-2 - alsa 1.0.12-1 - linux kernel 2.6.17.8 - lspci : ALi Corporation High Definition Audio/AC'97 Host Controller (rev 01) [a 939SLI-eSATA2 motherboard, with Realtek ALC 660 5.1 channel CODEC with HD Audio] - no asoundrc file
the wav file contains BIP sound, first on one channel, then the other one. File created with audacity. > as for time drifts when using JACK, forget about it.

Well I work with a Magnetic Resonance Imaging machine (MRI), and the generated sound must be rather accurate : the software is allowed to have a time drifting of 1 milli-seconde in sound generation. I was considerating that small wav files (about 3secondes) pre-loaded, will be a good choice, what do you think ?
