@redu By the way, do you have pulseaudio-module-jack installed?
is this chosen as your default device in jack? also try to uncheck the realtime-priority tick.

What realtime priority and who cannot have? I use default kernel (no RT or lowlatency even) and jackd (and jack1) works fine. But are you using Ubuntu or Debian, or you are using Archlinux and think the kernels are the same? What you mean by "same"? They may differ in version, config opts...

How can low latency kernel resolve broken jackd start? Pretty easily, especially if it is jack1. It cannot have realtime priority and it doesn't start. My bet is that its something that the user underestimates or overlooks. Not saying much... :lol: What realtime priority and who cannot have? I use ...

Try installing the low latency kernel and try jack again. How can low latency kernel resolve broken jackd start? Pretty easily, especially if it is jack1. It cannot have realtime priority and it doesn't start. My bet is that its something that the user underestimates or overlooks. Not saying much.....

Install ubuntustudio-installer from your software center. You should have at least the lowlatency kernel and all the settings provided. By the way ubuntustudio-controls app, is currently my favorite JACK client. PS: Guys. Some of you needlessly over-complicates some Linux Audio related issues. Not a...

Maybe that's part of the problem. Frequency should be 1000 Hz. cat /boot/config-`uname -r` | grep HZ CONFIG_NO_HZ_COMMON=y # CONFIG_HZ_PERIODIC is not set CONFIG_NO_HZ_IDLE=y # CONFIG_NO_HZ_FULL is not set # CONFIG_NO_HZ is not set # CONFIG_HZ_100 is not set CONFIG_HZ_250=y # CONFIG_HZ_300 is not s...

OMG: I found what's responsible for that mess. I almost thought my CPU or RAM is broken, but it was the #GRUB threadirqs boot option This is just for information. I don't claim, if it directly apply to you lilith Have in mind that the threadirqs option is not needed for realtime kernels. And even i...

There a a couple of more switches for the cpu's which have by far more influence on the performance of your system, then anything you could do with the priority settings. Give me an example for that "CPU switches"?. The idea for the CPU governor is to save power. And logically this will d...

As far as I understand it slowly increases the DSP load and detects at which DSP load the first xruns appears. In addition it also shows the number of cycles. If your system is well configured you should reach 95% or more. What I don't understand is if a DAW that runs with higher priority in the ba...

In fact the way to actually boost the performance and minimize the xruns, is to stop networking, during your music sessions and to look and check off any startup modules and services, that you don't use. Does this also account for networking via LAN? Yes it does. Theoretically not as much as WIFI, ...

Hi Digital Larry Ubuntu Studio (especially the recent versions) is set to optimize audio performance out of the box. You really don't need to change anything in the system. Ubuntu Studio is already set off. In fact the way to actually boost the performance and minimize the xruns, is to stop networki...

Hi lilith and tramp I have two questions, from this ongoing conversation What does xruncounter does? What is exactly measured? How grep became so important object of interest for a Professional Audio? And /proc suppose to contain system data only. Nothing interesting for me and you. PS: What is the ...

Yes
This command will install the latest linux-image-lowlatency from the repositories. This is the "Debian Way"

There is no issue with selling a Linux distribution. I agree there I find nothing morally wrong with selling a Linux distribution, as long as you are transparent about it and provide the full sources (including all configuration and build utilities). I think the GPL puts this fairly nicely: Actuall...

Regardless of how the particular Linux kernel is called, if you don't have PREEMPT option enabled, you cannot assign priorities whatsoever. Neither by Jack nor Rtirq. If you have PREEMPT enabled, but not RT, you can assign priorities up to 89. Have that in mind when you set your system. The reason i...
