ScottLNightrav1n, can you send an email to the -devel mailing list?01:01
ScottLand thanks for hanging in channel long enough to get a reply ;)01:01
ScottLNightrav1n, ubuntu-studio-devel@lists.ubuntu.com01:02
* micahg should probably subscribe to that01:32
ScottLmicahg, it's not as exciting as you might think ;)01:33
stochasticNightrav1n, do you have a link of the image?04:29
micahgScottL: BTW, the ubuntustudio-meta upload should fix all the uninstallability except for wine04:53
micahgwell, wine + ia32-libs...04:56
ScottLmicahg, thank you :)05:23
* micahg hasn't done it yet, but still on the list05:24
* micahg goes and and does it05:25
micahgScottL: uploaded05:38
falktxhey there08:12
ailogood morning falktx 08:20
ailoNice day for coding, don't you think?08:21
falktxailo: yes!08:21
falktxI'll finish my canvas stuff and do a final test before cadence gets alpha1, finally08:21
falktxtime to make some music!08:21
ailoI'm doing some puredata patches myself. Making a custom app for sequencing and recording music.08:23
falktxnice08:27
* abogani waves all09:40
abogani... the jackd realtime threads should run at a priority higher than the standard IRQs but lower than the audio-related ones  ...09:40
aboganiWhat priority we use for Jackd in Ubuntu Studio?09:41
ailoabogani, The file /etc/security/limits.d/audio.conf, which is added when installing jack, has this setting:09:48
ailo@audio   -  rtprio     9509:48
ailo@audio   -  memlock    unlimited09:48
ailoI assume this is what you mean09:49
ailoUsers in "audio" group are able to start jack with these settings09:49
aboganiailo: Those are upper limits. I meant jackd's command line -P parameter or qjackctl (priority value).09:51
ailoabogani, There are no added parameter what I am aware of09:53
aboganiailo: Hmmm so we don't provide a reasonable default value... :-(09:54
ailoabogani, Ubuntu Studio uses the default settings created by just installing jackd. Performance is good. But, if I do ..10:01
ailops -eo pid,rtprio,ni,pri,comm10:01
ailo  PID RTPRIO  NI PRI COMMAND10:01
ailo24129      -   0  19 jackd10:02
ailoIs this what you mean?10:02
aboganiailo: Yes.10:03
ailoqjackctl has a parameter called "priority" and it is set to "default"10:03
* abogani is wondering about the numeric value of that "default"...10:04
shnatselyou can look it up in gnome-system-monitor10:05
shnatselit's called niceness10:05
shnatselnegative niceness values mean higher priority10:05
shnatselpositive niceness means lower priority10:06
shnatsel-20 is the highest possible priority10:06
shnatsel19 is the lowest possible priority10:06
ailoshnatsel, We're talking about something else10:06
shnatselah10:07
shnatsel:(10:07
ailoshnatsel, Are you talking about the qjackctl parameter called "priority"?10:07
shnatselnot sure about qjackctl, never seen it10:07
shnatselbut that's what most apps use because it's an OS mechanism10:08
ailoabogani, changing that parameter does not change anything. Still: "28568      -   0  19 jackd"10:08
ailoabogani, But, I can see that changing "priority" to 20 causes this commandline argument "jackd -P20"10:09
ailoabogani, No effect, anyway. But still, good performance10:15
ailoI'm looking into what the default value might be10:24
aboganiailo: Thanks, that is very important.10:25
ailoabogani, I've been told the default value is 1010:28
ScottLmicahg, outstanding!  thank you again :)15:39
ScottLabogani, ailo , we are looking at adding sane default jack settings this cycle15:41
ScottLholstein and someone else came up with some but we working on how to implement the settings during installation15:42
aboganiScottL: ok15:42
ScottLif there is a particular settings you think should be included please let me know15:43
aboganiScottL: rtirq set 80 as priority for snd so I *suppose* the right valued should be 79.15:44
ScottLabogani, i will note that15:45
ScottLthanks :)15:45
aboganiScottL: I'm not a Jack expert so please verify my supposition.15:46
scott-upstairsman, skaet runs a tight meeting for the release team meeting16:01
scott-upstairsTheMuso, this is cjwatsons response to the preseed issue you and len discussed on the mailing list : http://bazaar.launchpad.net/~ubuntu-cdimage/debian-cd/ubuntu/revision/172816:08
scott-upstairsi haven't a clue if this really fixes the problem by simply looking at the code16:08
Nightrav1nstochastic: yeah sure :) want a pm or shall i post the links to the channel? :)16:44
falktxscott-upstairs: ScottL: u there?17:01
scott-upstairsfalktx, aye, kinda in a release team meeting but i can probably talk for a bit17:01
scott-upstairsshoot :)17:01
falktxscott-upstairs: I really though deeply about what distro I should focus on. it's no doubt Ubuntu needs more work and help, so I guess I'll stick with Ubuntu17:02
scott-upstairsthat's fantastic for us ;)  but i feel that the arch people are going to loose something special then17:02
falktxArch users always have AUR17:03
falktxit's archaudio devs fault for being too slow17:03
falktxthe project is there, but seems stuck :(17:03
falktxscott-upstairs: anyway, Ubuntu 12.04 should be the focus now17:03
falktxis anything fully decided on the theme?17:04
falktx(ie, drop the current one and start a new?)17:04
scott-upstairsah, i'm sorry to hear that about the arch progress17:05
ScottLfalktx, i think there is going to be a great deal of development over the next two years for ubuntu studio and i think you could be a big part of that17:58
ScottLi think this is going to be an exciting time17:58
falktxScottL: i'm very sad that linuxsampler is not on Debian though18:05
falktxno linuxsampler, no openoctave18:05
ScottLfalktx, what can we do to get those applications into debian18:31
falktxno idea18:32
falktxI mean18:32
falktxwe need to fully understand why it's not there yet18:32
micahghttp://bugs.debian.org/578787 <-- openoctave18:32
ubottuDebian bug 578787 in wnpp "ITP: openoctave -- MIDI and audio sequencer and musical notation editor" [Wishlist,Open]18:33

micahgsame with openoctave it seems18:35
falktxI think it's time to join the debian multimedia team19:03
micahgfalktx: the team welcomes help19:09
