Again, Marcos' selection of a | lightweight | desktop (iceWM + ROX Filer) proves he understands the | scope of the | project and how to reach those goals. | | When researching information about Ubuntu Studio and | sound with Ubuntu, | I came across some very useful documentation | https://help.ubuntu.com/community/Sound. The Ubuntu | Studio Preparation | page has brief yet useful discussion about Kernel | Preemption and XRUNS. | In that discussion, there is a link to a document on | compiling a Kernel | with Real Time Preemption: | https://help.ubuntu.com/community/HowToVanillaKernelWithRealtimePreemption |. | | | Since Musix is based on Knoppix which is based on | Debian, and Ubuntu is | based on Debian, the documentation above should work. | I have Debian | Stable installed on a Mac G3 Blue and White, and | hopefully I will have | time to test the documentation. | | Please don't do kernel experimentation on a system | with important data! | | I hope this helps. Yes it helps, and thanks for your words, but I must tell you that thae Musix's kernels followed, in part, those Ubuntu Studio's tutorials, so, the work was done... but, sure, if the user is an experiences one, he could buid a new kernel I suggest to Try the 2.6.16-multimedia kernel that it's into Musix, Also, the 2.6-16-beyond4.1 it's a realtime kernel... To try it, start jack and type into a konsole: ps -C jackd -cmL You must see something like this: ps -C jackd -cmL PID LWP CLS PRI TTY TIME CMD 11213 - - - ? 00:00:00 jackd - 11213 TS 19 - 00:00:00 - - 11218 TS 20 - 00:00:00 - - 11219 TS 24 - 00:00:00 - - 11222 FF 90 - 00:00:00 - - 11223 FF 80 - 00:00:00 - If there are no FF, it's not in realtime, also, Musix 0.99 tells you if you are not using a realtime kernel. Julien: is realtime-lsm loaded? Type into a konsole: lsmod | grep realtime ............ If you want more evidences: marcos@musix099b16:~$ cat /boot/config-2.6.17-2-multimedia-486 | grep -i realtime CONFIG_SECURITY_REALTIME=m marcos@musix099b16:~$ cat /boot/config-2.6.16-beyond4.1 | grep -i realtime CONFIG_SECURITY_REALTIME=m .............. Julien, what could be wrong with zynaddsubfx? or does it happends with any other apps?
