You can; but you have to use special software, because yours is a special case. The normal desktop/laptop user does not use a synth. > ALSA/Pulse needing third-party stuff just to get basics right (acceptable > latency; not *ultra* low latency, just acceptable one) is a sign that > they're not designed right. Your definition of "acceptable" is *ultra* low to me, and many others. To me acceptable latency means that the audio system does not waste my laptop/phone battery. > And in the end, you know what?

To me Alsa+PulseAudio works better because it allows the battery of my laptop to last for hours while I see a movie with my bluetooth headset. With the latencies you want, that's not possible. I believe my use-case is more general. > At least it gets the basics right. Other > operating systems are much more advanced in that manner. It's ALSA that > holds Linux audio back. Jack uses ALSA. From the Jack FAQ page (http://jackaudio.org/faq): <quote> Doesn't use JACK add latency? There is NO extra latency caused by using JACK for audio input and output. When we say none, we mean absolutely zero. The only impact of using JACK is a slight increase in the amount of work done by the CPU to process a given chunk of audio, which means that in theory you could not get 100% of the processing power that you might get it if your application(s) used ALSA or CoreAudio directly. However, given that the difference is less than 1%, and that your system will be unstable before you get close to 80% of the theoretical processing power, the effect is completely disregardable. </quote> ALSA works great. And for regular users, with PulseAudio both are full of awesome awesomeness. For your use-case, you should try Jack.
