I get the same behaviour when capturing audio, Brahim; not sure if that's of any help. I don't tend to use playback at all (system captures audio almost exclusively), but it definitely just happens at initial binding and opening of audio device.

Can you try to edit your sample/audio and remove the dc content using e.g.
a trial version of WaveLab, and also make sure the beginning and end of your
sample are fade in and fading using a short ramp.

I can try here your sample on a TOBI, Chestnut, PALO35, etc can you share
your sample ?
