Low Latency vs. Real Time Kernel
by Brian Monroe 10 Nov '14

10 Nov '14

I've been spending a lot of time on the #opensourcemusicians channel talking to Ubuntu Studio users about their kernel and latency times they're getting. Seems like most of them are using g a stock kernel with the preemptive option enabled and they are getting great latency results (2ms)while utilizing the @audio group on their user. I ended up compiling my own low latency kernel and I haven't had any issues with it yet. If this is what we are missing for the spin I'd be happy to maintain packaging for the kernel. I know ccrma has been behind a few kernel releases. I saw the instructions for adding the real time patch for a tick less kernel and from what I can tell it wouldn't be hard to get that rolling as well. I'm not entirely sure what ccrma does differently with their kernels compared to other Linux users, and I'm still a bit of a noob so I could be off base with this, but I would reason that we should be able to just utilize the same settings to archive similar performance enhancements. I thought I read that ccrma uses a unique scheduler, but if we could get a 2ms latency time without it, the point may be moot.

Updating the wiki
by Brendan Jones 22 Nov '12

22 Nov '12

Hi all, I've created a page on the wiki for configuring Jack. I've copied parts from the Musicians guide, the Jack README and added a section regarding rtirq. It is by no means complete. Missing things that come to mind are common bugs, a2jmidid, Jack/ALSA bridging etc. We probably need one for pulseaudio as well, with particular emphasis on starting and stopping pulseaudio, logging and bug reporting, jackdbus integration, jack module loading, pacmd startup scripts in qjackctl, and the new jam-control app Please feel free to log in and make corrections changes and additions. It would be great of we could come up with a comprehensive wiki for new Fedora users that is at least as good as that provided by other distros like Arch. Here's the new Jack page: https://fedoraproject.org/wiki/JACK_Audio_Connection_Kit And here are existing pages in the wiki that need updating/reorganizing: https://fedoraproject.org/wiki/How_to_debug_PulseAudio_problems https://fedoraproject.org/wiki/How_to_troubleshoot_sound_problems regards, Brendan

Heads up: jack problem on F-17
by Orcan Ogetbil 15 Nov '12

15 Nov '12

Hi all, I accidentally pushed a optimized jack build jack-audio-connection-kit-1.9.8-10.fc17 to the stable repo, which reintroduces the verbosity problem[1] (Strangely, when I built this package locally, I did not have this issue ). For now, please keep your jack version at jack-audio-connection-kit-1.9.8-9.fc17, or use the optimized but non-verbose builds from [2]. I will keep you updated as soon as we come up with a solution. I apologize for the inconvenience. Best, Orcan [1] https://bugzilla.redhat.com/show_bug.cgi?id=827748 [2] http://oget.fedorapeople.org/jack/

Fedora Jam KDE theme - review required
by Brendan Jones 13 Nov '12

13 Nov '12

fedora-jam-kde-theme is up for review [1]. Some screenshots here [2]. Still not sure if this will pass the Spins review process but we will see. With this in mind I've tried not to rock the boat to much by going with the spherical cow splash icons and basing the wallpaper on the F18 theme. If any reviewers could pick this up that'd be great. We need to get this reviewed ASAP. [1] https://bugzilla.redhat.com/show_bug.cgi?id=875735 [2] http://bsjones.fedorapeople.org/projects/fedora-jam-kde-theme/
