JFTR, I've seen ardour running on an Audinate Dante PCIe card last summer at musikmesse. They have made a proprietary Linux driver to drive their WFS systems. Unfortunately, I forgot the company's name, all I know is it wasn't IOSONO. Though proprietary drivers are clearly nothing one should wish for, it seems there's at least something going on in network-driven audio. Intel has recently released an Open-AVB stack, and we'll discuss jackd integration any time soon. https://github.com/intel-ethernet/Open-AVB Last not least, the RAVENNA camp has stuff ready that might benefit from Intel's recent kernel changes.

Mostly wrote it to start a conversation and hear what others have to say on the subject. http://www.louigiverona.ru/?page=projectss=writingst=linuxa=linux_progress You can comment here or on my textboard (which does not require registration). Interesting reading. From an user perspective, I have been used GNU/linux from quite some time now (back from my 386 box), and I have seen very things to appear like ALSA and JACK. In recent years, the biggest improvement was jack2 on multiprocessor machines. It is just much more easier to get the job done because the processor use is lower. This give us also a better stability at high system load. .But in the same time, I have seen a couple of choices coming, which are not directly related to the linux audio community, but can influence us badly if such idiotic choices are becoming the norm into GNU/linux in the future. More specifically, if I do understand the need for some big corporations for stuffs like policykit and consolekit, I just have no use for them in an audio pro box. So, I don't want them, and the recent decision to include a java script interpreter into polkit (in order to try to make it to become manageable...) will certainly not made me to change my mind: I have other things to do with my time than to learn JS in order to be able to make system administration, and I will not pay for that either. The worst thing with polkit, what is completely idiotic, is than it is a mandatory dependency of gnome. In consequence, when installing any gnome related program, this will install polkit and consolekit, and something as simple and efficient than startx will become broken, because as soon than polkit is installed, it is forcing you to run consolkit in order to be able to launch xorg with your favourite and *kit free wm/desktop. In consequence, my box today is not only completely windows free, but also completely gnome free. The kernel is a terrific tool. It just do its job, and it do it very well. And we have plenty of terrific audio tools. To speak generally, I think than another consequence of such idiotic choices is than we need to keep a close eye on what is going on in userland.

But it irks me to see people continue to make this claim about jack2. Let me reiterate: the normal version of jack2 does not and cannot use multiple processors if the data flow is serialized. Mutiple processors are only used where there is parallel flow between clients. Although this is not unheard of (e.g. two synths flowing into a DAW), its unlikely to be the common case for most users. Many people find jack2 to be more stable because it does not zombify clients in its default mode operation. It allows clients to be late by a substantial amount, which can result in clicks and pops in their apparent audio stream, but doesn't cause the server to kick them out in the way that jack1 does. One way to look at this is that jack2 is more tolerant of programming errors and system latency than jack1. --p ___ Linux-audio-dev mailing list Linux-audio-dev@lists.linuxaudio.org http://lists.linuxaudio.org/listinfo/linux-audio-dev

Sure, John. I did not try to organize this. It might be possible, of course, in theory. And maybe it is one of the solutions - to have a place (possibly like kickstarter) where we can organize driver jobs. I don't know how realistic this is though, but could be worth a try.
