Re: [LAU] perhaps why some of us have more trouble w/ pulseaudio than others (ICE1712/M-audio delta problem w/ pulseaudio)

JACK is cool, but its latency and "performance" focused design is a liability on designs where the consumption of CPU cycles, memory and above all consumption are primary considerations. Apple again did the right thing here by coming up with a design that works almost equally well for high latency and low latency applications, but even Apple has had to promote a different API for iPhone and iPad developers that looks more a traditional queing model than the callback-focused design of traditional CoreAudio (and JACK). Saying that JACK is "better" than PulseAudio is like saying that more(1) is better than cat(1). Or that my Honda Fit (Jazz for europeans) is better than my neighbour's Ford F150 truck. They don't try to solve the same problems. They don't even really want to solve the same problems. And most importantly, AFAIK their developers don't want to solve the same problems.
