also, just to be clear: sure, there's still poll(2) involved. the point is not that its cheap (this is what Abramo and I disagreed about originally, and he turned out to be right - its cheap *enough* for many things), but that it encourages/enforces program design that allows desirable things to be done. i spent some time last week porting a nice little app called RythmnLab to use JACK. it used the same kind of design that so many linux audio apps do - blocking reads and/or writes on the audio device. this approach just can't be used for low latency sample sync'ed performance. its precisely this goal that is so important to the Windows/MacOS proprietary s/w developers these days, and it should be for us as well, IMHO. --p _______________________________________________ Alsa-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/alsa-devel
