View Full Version : Planet CCRMA for F14?
11th October 2010, 05:14 PM
I see that Planet CCRMA only goes up to Fedora 12. http://ccrma.stanford.edu/planetccrma/software/ Is there any chance it will get updated soon?
I see that there is an audio spin, http://fedoraproject.org/wiki/Music_Creation_Lite_Spin but I was mostly interested in a real-time kernel.
Is the audio spin/remix for Fedora 14 likely to happen? http://fedoraproject.org/wiki/AudioCreationSpinDevelopment

There is indeed a Planet CCRMA At Home repository for fedora 13:
Look at the testing repo for newer stuff. No doubt there will be an f14 repo as well when 14 is released. Somebody really should volunteer to update their website.:rolleyes:

Yes, I saw some links for Fedora 13 after I posted. I guess I'll look into compiling a real-time kernel for Fedora 14. I really like Nouveau, and don't want to downgrade.

If you haven't done so already, check out the CCRMA mail list: http://ccrma-mail.stanford.edu/mailman/listinfo/planetccrma
There is probably some help there with nouveau and the RTK.

I looked, but it was mostly people complaining about nVidia's drivers. I've got a real-time kernel without debug compiling right now, hopefully all will be ok. I wish someone on Koji would pickup compiling "multimedia" real-time kernels with separate debuginfo.

Real-time kernel without debug hasn't helped so far. Must be a Jack/Pulse/Alsa/FluidSynth/position of the moon/ audio recording problem. I'll start a new thread if I can't get it working.
How crazy, I had to make all these changes for better Linux audio. Get "hg clone https://realtimeconfigquickscan.googlecode.com/hg/ realtimeconfigquickscan" and run "perl QuickScan.pl" to see what changes you need to make. LinuxMusicians website really helped out!
I recompiled Fedora 14 Updates-Testing kernel 22.214.171.124-39.fc14.i686 with seperate debuginfo, and real-time kernel support set to 1000.
Also added these lines to /etc/security/limits.conf
@audio - rtprio 99
@audio - memlock unlimited
And added new 40-rtc-permissions.rules file in /lib/udev/rules.d with
Changed settings in /etc/security/limits.d/99-jack.conf to
@jackuser - rtprio 99
@jackuser - memlock unlimited
@pulse-rt - rtprio 99
@pulse-rt - nice 0
Added new 40-hpet-permissions.rules file in /etc/udev/rules.d/ with
Added this to /etc/rc.d/rc.local
echo 2048 >/sys/class/rtc/rtc0/max_user_freq
echo 2048 >/proc/sys/dev/hpet/max-user-freq
sysctl -w vm.swappiness=10
sysctl -w fs.inotify.max_user_watches=524288
I enabled ACPI 2.0 support on my motherboard.
I didn't change to GOVERNOR=performance in /etc/sysconfig/cpuspeed, since my computer is old, and my motherboard settings are conservative.
I changed the default Capture device in alsamixer to only PCM for recording internal audio, otherwise I got loud static.
I changed the default connections from System into my recording app, to Qsynth into my recording app for MIDI recording into audio.
