I had a lot of latency problems running Ubuntu 8.10 with a realtime kernel. And nothing changed modifying the limits.conf file and adding myself to the audio group. So I decided to install <a href="http://www.musix.org.ar/">Musix</a>. I think it is the best distro for audio-linux ever. At first glance it looks rather messy but it works as smooth as a Mercedes-Benz. <br>
<br>I've reached latencies of 3 ms. with no trace of xrun nor clicks in the audio, while in Ubuntu I just could barely get close to 25 ms which was insane. I cannot recommend anything else. Trust me.<br><br>Good luck!<br>

Hi Tom,<br>
<br>
I just went fine with the instructions on the jack-faq-page (<a href="http://jackaudio.org/faq" target="_blank">http://jackaudio.org/faq</a>). Did you add these lines to your /etc/security/limits.conf ?:<br>
------------------<br>
@audio - rtprio 99<br>
@audio - memlock unlimited<br>
@audio - nice -19<br>
------------------<br>
Do not forget to add yourself to the group 'audio' and re-login. This in combination with the rt-kernel works great for me.<br>
<br>
Regards, Thomas<br>
