Let's focus on the important parts. It's a Wiki about professional usage. I don't claim that low latency is unimportant. It's also important when playing virtual synth, but users shouldn't try to archive latencies between 1 ms and 5 ms, because this is hard to archive. If this works it's very good, if just latencies around 10 ms are possible it's ok, too. More important is to optimise everything to get a reliable system. Again, I don't claim that it's absolutely irrelevant to e.g. compile with "Timer Frequency is set to 1000Hz (CONFIG_HZ_1000=y" but usually hrtimer is used by default, e.g. by Qtractor. To optimise more for e.g. MIDI usage users should consider to run jack2 with -Xalsarawmidi. There also is an option for jack1, but I'm not a jack1 user, so hopefully somebody could help to edit the Wiki. It's the Arch Wiki, the recommended kernel from AUR (btw. there's also a LTS RT patched kernel available) for good reasons dropped 1000 Hz. IOW the AUR kernel is opposing to the hints provided by the Wiki. If 1000 Hz are still required, then we should clarify this. I just asked you to help to get the Wiki up to date and to _discuss_ controversial opinions, as well to explain some things that aren't explained. I can't understand the resistance and hostilities. What's wrong with trying to make the Wiki better? It was good, but seemingly isn't up to date. For example, I already removed "If you want to use any MIDI hardware you need to ensure the ALSA MIDI driver is loaded. You can set the MIDI driver to load at boot by creating the file /etc/modules-load.d/alsamidi.conf containing:" For what reason? This happens automatically. "Warning: Enabling threadirqs seems to be causing system lockups in conjunction with usb devices in at least some kernel versions starting with 3.13 and including at least 3.14-rc2. See for example https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1279081 and http://www.spinics.net/lists/linux-usb/msg102504.html also linked from there. EDIT: The changelog seems to indicate that this has been fixed in the 3.13.6 vanilla kernel. (Search for threadirqs in https://www.kernel.org/pub/linux/kernel/v3.x/ChangeLog-3.13.6)" No such kernel is still provided by Arch Linux, even the LTS kernel is 4.9.18. Does somebody need flash for pro-audio? In short, if somebody wants to set up an Arch Linux PC for pro-audio it's better to avoid clutter and to focus in short, of the important things.

Somebody else did ;). The Wiki is confusing and needs to be reworked. expansion. Regards, Ralf -- "Michael" described Floyd as "an idiot savant", and added, "Give him any two numbers, and he can multiply them in his head, just like that." Homer, testing Floyd, said, "Five times nine", and Floyd instantly responded "Forty-five", which impressed Homer. _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
