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 available for Ubuntu 13.04. Meanwhile, you can build the Linux RT kernel yourself. Follow the instructions in <a href="https://rt.wiki.kernel.org/index.php/RT_PREEMPT_HOWTO">https://rt.wiki.kernel.org/index.php/RT_PREEMPT_HOWTO</a> for details.

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 disabled pulseaudio). Even though i use a Roland ua25-ex that stands undisturbed upon its interrupt line... Any tips eventually?
