Well, since i don't know anything about mmap'ing device files, i would be glad if somebody could point me to sources of information about mmap'ing device files and especially the differences in handling of ALSA and OSS.. P.S.: the test case here is running Enemy Territory with aoss. Try it and you will see how alsa-oss' mmap emu fails badly [only some craacks and little chunks of audio audible].. -- Palimm Palimm! http://affenbande.org/~tapas/wiki ------------------------------------------------------- This SF.Net email sponsored by Black Hat Briefings & Training.
