len_1304Lumpy, new version of Pulse out. I have been playing with PA+linphone+jack+idjc.01:28
len_1304Machine = a-bit MB with P4 at 2.4Gh with 2.5G ram. Running US Version R. Bios has hyperthreading turned off (allows -p16 to work with guitarix).01:31
len_1304For this experiment Jack is running at -p 512 for 23 ms latency.01:33
len_1304jack and pulse (even bridged) are idling at about 1% cpu each. The pa-jack bridge is stereo only.... I don't know if mono would help.01:34
len_1304Pulse is set to have all audio cards turned off so that the jack bridge will always be default when the phone connects.... and to avoid any weird behaviour of PA/jack interacting with two cards at once might introduce.01:38
len_1304At idle, phone hung up, idjc streaming but not playing any music file... idjc runs about 10% cpu. With music playing, that goes up to 40ish%, closer to 50% if the sample rate of jack and the file are different.01:41
len_1304for this reason I am running rate of 44100.01:42
len_1304Opening the mic seems to have no effect (it shouldn't) so the act of introducing audio from the phone to idjc would be the same.01:43
len_1304The phone rings, gets answered and the phone opens ports to pulse. The phone starts using 50% or so cpu. Idjc also goes up. The audio from/to the phone gets choppy even though jack is not yet showing xruns, so the chop is all the pa/phone side.01:47
len_1304If idjc is also playing music... the whole audio chain goes into oscillation... I can recover from it by backing out one app at a time, but the set up is not usable.01:49
len_1304Lumpy, this set up would require more cpu horse power than I have. I do not know if two cores would be enough or not.01:58
len_1304The phone on gmail is much better but the latency is up around .5 or more sec.02:06
len_1304Nope I got it wrong, streaming takes 30% cpu. The player doesnt take that much unless the rate is different from jack.02:30
shai_haludholstein: earlier you mentioned something about a wav to midi program. what is the phg name i need to look for?04:23
shai_haluder pkg04:23

mick_yes its a tascam external sound card08:36
mick_what is a good interface to use with studio?09:50
mick_Can someone give me some clues as to which sound card I should consider?10:43
shai_haludgreetings!10:55

shai_haludhi Zeke11:00
zequenceshai_halud: Hi. I was wondering who Zeke was :)11:02
shai_haludhaha11:03
shai_haludthat's YOU11:03
shai_haludare you terribly busy?11:03
shai_haludi am trying to compile latest vers of lmms and after having gotten through about a gig of dependencies, still come across some errors. i have a paste ready to upload if you can sort of enlighten me as to what  the remaining errors mean11:05
zequenceshai_halud: shoot11:05
shai_haludone sec11:05
shai_haludhttp://pastebin.ca/232760611:06
zequenceshai_halud: I would recommend #lad and #opensourcemusicians also. Many of the application developers hang out at #lad11:06
shai_haludok11:06
zequenceshai_halud: Did you do this? "after installing missing packages, remove CMakeCache.txt before"11:09
shai_haludevery time11:09
zequenceOk, just checking11:09
shai_halud(about 20-30 times)11:10
shai_haludi exaggerate slightly11:10
zequenceshai_halud: Oh, try this btw. sudo apt-get build-dep lmms11:10
zequenceThat'll install all build dependencies11:11
shai_haludSWEET11:11
shai_haludthat's what i was wishing existed11:11
zequenceYeah, it's handy11:11
shai_haludOnly 31 megs to dl11:13
shai_haludwheeee11:13
shai_haludok. i think cmake got far enough that time11:15
shai_haludLooking for pthread_create in pthreads - not found11:16
shai_halud    and QS_WIN also11:16
shai_haludprocess.h11:16
shai_haludseems nothing fatal11:16
shai_haludoh, and this:11:17
shai_haludooking for include file /usr/src/sys/gnu/i386/isa/sound/awe_voice.h11:17
shai_haludwoohoo. running make11:19
zequenceshai_halud: Why are you building lmms, btw?11:24
shai_haludbecause i couldn't find a precompiled version of 4.1311:24
zequenceOk11:24
zequencecould be kxstudio repos have it11:24
shai_haludnope11:24
shai_haludi am compiling theirs now11:25
shai_haludLMMS website is same11:25
shai_haludi figured ksstudio might be a little beefier. it is 1 meg larger11:26
shai_halud80% make, no errors11:26
shai_halud2 erros11:27
shai_halud i wonder what they are11:27
shai_haludwine errors11:28
zequence64bit might not work with wine11:28
shai_haludok make install finished. now to see what it made11:29
shai_haludcrap . it has no presets11:33
shai_haludhm11:34
shai_haludeverything else seems fine11:34
zequenceshai_halud: Would you be interested in helping out with Ubuntu Studio development/PR/testing? It's not a big question really, and doesn't require much involvement. I'm on the verge of trying to get more people involved. We have all kinds of things we'd like more people helping out with11:36
shai_haludi certainly would, if i am able11:37
shai_haludthough i'm afraid my skills are rather meager.11:37
zequenceshai_halud: Check out the wiki https://wiki.ubuntu.com/UbuntuStudio/11:37
shai_haludif there are ways I can help, I will glady do so11:38
zequenceWe don't need skills. Only will in most cases :)11:38
zequencewe hang out at #ubuntustudio-devel11:38
shai_haludwell, will i have in plenty11:39
zequenceshai_halud: This is our team structure https://wiki.ubuntu.com/UbuntuStudio/TeamStructure11:39
zequenceAs you might notice, we have more teams than members11:39
shai_haludand if there are opportunities for me to learn, EXCELSIOR!11:40
shai_haludhehe11:40
zequenceThe teams are not only categories for splitting up responsibilities. We work with launchpad a lot, and each team is also a launchpad team11:40
zequenceIt has some benefits doin it that way11:40
zequenceshai_halud: If you haven't got a launchpad account, get one. https://launchpad.net/11:41
shai_haludk11:41
shai_haludon it11:41
zequenceyou could begin by joining https://launchpad.net/~ubuntustudio11:41
zequenceBut, from there, it's really up to what you'd be interested in doing11:42
zequenceshai_halud: join #ubuntustudio-devel, and I'll talk more11:42
shai_haludok11:42
shai_haludgimme 5 to reggy11:42
mick_ok ill bite, got anything that will take around 20 mins of my time per day?11:46
mick_maybe more11:46
zequencemick_: We don't have a good structure for handing out work right now, also, I think one needs to get a look at the big picture a bit first, to see how we work, and then, hopefully, one can work independently a lot11:47
zequencetesting for instance is not very structure right now. It should be, and we need to make it so in the future11:48
zequenceWe need a vivid PR team, who posts stuff on mail lists, our website and social channels11:48
mick_hmm11:49
zequenceWe need people who work on our workflows, audio, graphics, video, etc to do research on what applications are available, and if we are using the right ones, if they are well configured, etc - more of a user related job11:49
zequenceRight now, we have too few people working on too many things.11:50
zequenceSoftware development, and handling Ubuntu Studio source is not the biggest part of what we do11:50
zequenceWe have our own kernel, and right now, I'm the maintainer of it.11:50
zequenceI will want for more people to learn that stuff too, and am preparing documentation11:51
zequenceOh, yeah. we need people who write docs too11:51
zequencemick_: The team structure let's you know what areas we work in https://wiki.ubuntu.com/UbuntuStudio/TeamStructure11:53
zequencemick_: shai_halud: blueprints is where we organize what we work on, who works on what, etc https://wiki.ubuntu.com/UbuntuStudio/PermanentBlueprintOverview11:53
shai_haludall pages bookmarked11:54
zequenceAll of the blueprints are at launchpad, so that is just an overview11:54
zequenceshai_halud: I've been making sure everything you need is avaible from the wiki, so shouldn't be hard to find stuff11:54
shai_haludk11:54
zequenceThe important sources of info are really: blueprints, IRC and mail lists11:55
zequencesome launchpad teams have special privileges, so if you need to post on the website, the PR team allows for that. That's why we have the teams11:56
zequenceSo, the first step is: become a member of launcpad. login to #ubuntustudio-devel, and subscribe to at least the Ubuntu-Studio-devel mail list11:57
shai_haludi'm in the channel now11:57
zequencemick_: You're welcome too11:57
shai_haludand perusing for the mail list11:57
mick_what was that link again I clicked on it and got lost, the getting started link12:03
zequencemick_: You have all the info from here https://wiki.ubuntu.com/UbuntuStudio12:04
zequenceNext to the orange developer section12:04
mick_thanks12:04
zequencemick_: login to #ubuntustudio-devel12:04

=== EricAndr_ is now known as EricAndrews
iorechelos, is there an easy way to upgrade from ubuntu to ubuntustudio without a complete reinstall?18:40
Unit193You can install the metapackage(s)18:44
iorechow would i go about doing that?18:45
Unit193You could install ubuntustudio-desktop, but they have several others as well, apt-cache search ubuntustudio   to see all.18:46
iorecand thats the full ubuntustudio "experience" then or just a hack?18:47
zequenceiorec: Depends on what you mean. You could easily just install the packages you want/need, but if you want a clean install, the only way is to use the official ISO18:50
Unit193It's how you'd go from one to the other.  However, you will have "leftover" applications you may not need.18:50
zequenceThere may also be some conflicts in user settings, if you have many desktop systems installed in paralell18:51
zequenceIf you don't need the desktop, just install the packages you want18:51
ioreck, it is mainly that i am having troubles with jack all the time. sometimes works, sometimes not, without changes...i am hoping that would improve with ubuntustudio!?18:51
zequenceTo get realtime privilege, you'll need to add yourself to audiog group18:51
zequenceTo get low latency, install linux-lowlatency18:51
zequenceiorec: That's a bug18:52
zequenceiorec: It crashes sometimes when you try to stop it18:52
iorecja, probably..at the moment it just won't start anymore.18:52
zequenceTo kill it, do: killall -9 jackdbus18:52
zequenceIt's probably frozen in the background18:52
iorecstarts with built-in soundcard, but no more with external usb-audio device18:52
zequenceAnd, also, it might not start, if pulseaudio is using the same device for something18:53
zequenceThat's also a bug, btw18:53
ioreci had pulseaudio killed completely..didn't change anything.18:53
iorecalso several restarts of usb-device and pc didn't help18:54
iorecwill try the killall -9 jackdbus18:54
zequenceHow did you kill pulseaudio?18:54
iorechow to start it then?18:54
zequenceHow to start jackdbus?18:54
zequenceEither with qjackctl, using the default settings, or from a command line: jack_control start18:55
iorecfound a blogpost about how to completely shutdown pulseaudio when having troubles with jack..followed that. pulse was obviously dead, but still no jack.18:55
ioreck, i have qjackctl18:55
zequenceAnd each time, the onboard would work?18:55
iorecjes onboard works18:55
zequencewhat does this show you? cat .jackdrc18:56
zequenceThat should be: cat ~/.jackdrc18:56
zequenceMine is: /usr/bin/jackd -dalsa -dhw:M66 -r44100 -p1024 -n218:56
HelloWorld321this one will be a little obscure: does anybody know if ~/.rstudio-desktop/sdb is supposed to have any .eml files in it?  I ran an unfortunate find script last night, and I'm trying to unwind it.18:57
zequenceHelloWorld321: Sorry. Don't know what that is18:57
iorecthis i get: /usr/bin/jackd -v -P1 -dalsa -dhw:0 -r44100 -p1024 -n2 -Xseq18:59
HelloWorld321zequence: tx.18:59
HelloWorld321If you're running rstudio under ubuntu, would you please type "ls -lart ~/.rstudio-desktop/sdb/prop/" and tell me if that directory contains files with no extension, or files with .eml extension18:59
HelloWorld321I think in a normal installation, they would have no extension; but I've accidentally renamed some to .eml19:00
zequenceiorec: Well, it's not too low buffer anyway.19:02
zequenceiorec: Which device is it?19:02
iorecmaudio quattro19:03
iorecfirst error i get on starting: ERROR: Cannot lock down 82241434 byte memory area (Cannot allocate memory)19:03
iorecthen it goes on19:03
iorecnext errro: RROR: ALSA: could not start playback (Broken pipe)19:03
zequenceiorec: The memory error would indicate you don't have realtime privilege19:04
iorecmkay, but why? since when?19:04
zequenceiorec: Check if you're in audio group: groups19:04
iorechow can i check that?19:04
zequenceUse the command "group" and see if "audio" is one of the results19:05
zequencegroups19:05
zequence..I mean19:05
iorecnope. apparently i am not in the audio group19:06
iorechow can i get an invite there?19:07
zequenceiorec: So, Quattro is probably not usb2.0 supported, right? Which would mean, you can't get 4 I/O, as the older usb specification doesn't allow for that19:07
zequenceiorec: sudo usermod -a -G audio $USER19:07
zequenceThe file for groups is in /etc/group19:07
zequenceYou can also edit it manually19:07
ioreci only uses 2 i/o's (haven't tried 4 at all)19:08
zequenceOn Debian, from where jack is imported, users are already members of audio group19:08
iorec*used19:08
zequenceiorec: So, do you specify that in qjackctl settings?19:08
iorecyes19:08
zequenceok, well. I've tried using the quattro, only quickly, and even though it started, I got static, just cause I didn't specify I/O19:09
zequenceanyway..19:09
iorecit worked for me.on and off..19:09
zequenceSomething that I've heard a lot is that using a Periods/Buffer of 3 is better for some usb devices19:10
zequenceBut, that would probably not help19:10
zequenceiorec: Does it work at all with pulseaudio?19:11
ioreck, will now try to get me in that audiogroup19:11
iorecnot sure about pulseaudio..19:11
zequenceiorec: You'll need to log out and in again for that change to take effect19:11
iorecok. now also waiting for the ubuntu 12.10 update to finish19:12
zequenceiorec: So, whenever you try starting jackdbus, if it told you it could stop, make sure to kill it before attempting again19:18
zequenceiorec: No PPAs, btw?19:18
zequence..couldn't stop the, the previous time you tried to stop it, I mean19:18
iorecPPAs`19:19
iorec?19:19
