I did some more test and measurements (see http://www.grame.fr/~letz/jackdmp_solaris.html section Timing measurements). A strange behaviour I had doing these tests: on OpenSolaris, with a high CPU load when accessing devices in O_EXEC mode, I had this "distorted sound" up to the point a write underrrun was detected (after several seconds) and... the sound not distorted anymore! But this behaviour did not happened on Solaris (on the same machine) where the sound stayed distorted.
