Rosegarden with ANGULA Kernel
I've been trying to get JACK to run for Rosegarden but in the tutorial it says that you need to use the Angula kernel for it to work properly. Is this true? And if I do need to run Angula can I run it from a Live CD?
When I try to start JACK it gives me an error and tells me that JACK can't start. This is the message: 03:54:36.616 JACK is starting... 03:54:36.616 jackstart -R -P10 -dalsa -dhw:0 -r48000 -p512 -n2 -S -M 03:54:36.624 Could not start JACK. Sorry. Thanks. |

You don't need an agnula kernel, but if you want to use the -R parameter you'll need a kernel that supports it. My kernel (2.6 series) kernel was built with the 'realtime-lsm' patch, if you load the realtime module you can give certain apps realtime priority. I use Rosegarden without much trouble on Vector Linux 5.8, the kernel is already patched for realtime support and there's a Rosegarden package in the repository. |
You might want to study on the 64Studio distro. Comes with realtime kernel.

you are most likely looking at an old tutorial.
there is really no reason to have to use a special kernel. 2.6 kernels generally do OK with audio as they are. but you have to get user realtime access somehow. the current way to get realtime access as a user is with PAM compiled with rtlimits. the kernel module realtime-lsm is the old (no longer maintained) depreciated way. you may even already have a version of PAM ready to go. look at your file /etc/security/limits.conf possibly just uncomment some lines that look like this Code:
@audio - nice -10 But some GUI toolkits prevent this so some GUI apps won't start. |
I got Jack running. Thanks so much to everybody. 64Studio looks really interesting. I might give that a shot. Thanks again.
