Hi all,
Just an update.
I compiled my own rt kernel following the system configuration guide
http://wiki.linuxaudio.org/wiki/system_configuration#the_kernel
I've used the linux-3.2.35 kernel with the 3.2.35-rt52 patch compiled
against the .config of the latest low-latency kernel available from

Hi all,
Is it available a Real Time kernel for the 13.04?
I've tried both the default lowlatency kernels but to be honest i'm not
satisfied with them.
With my hp pavilion g6 can't get good results with jack below 11,6 ms
(many xruns) even if i tried several further configurations (ex, i

PS: What issues do you experience? Can you please post the output of
rtirq status?

That Laptop has limited cpu and I/O resources for the many apps that can
run on this kernel thus you get plenty of xruns. In other words, you need
more hardware resources. Perhaps if you use an externel usb sound card you
may get some help. You need to be at 8Gb of Ram and a high speed hard
Hi Nicola,
google for KXStudio, perhaps it provides linux-rt for Ubuntu 13.04, if
not, then I can explain how you can build your own kernel-rt. Since I'm
short in time, I only will do it, if no linux-rt should be available by
a repository.
Regards,
Ralf

Hello Nicola,
A packaged RT kernel for Ubuntu 13.04 is not available via any repository
or PPA currently. We do have plans to resume maintenance of the linux-rt
package in the near future (possibly after the release of Ubuntu 14.04
LTS). However, I don't think a packaged RT kernel will be

First of all, thanks everyone for your quick replies.
Second, it's the first time that i write here but i'm a happy ubuntu studio
user since 9.10!
So thanks to make this distro as great as it is...hope to contribute myself
more in the early future.
Now, i attach the output of these commands:
