[01:28] <len_1304> Lumpy, new version of Pulse out. I have been playing with PA+linphone+jack+idjc.
[01:31] <len_1304> Machine = 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).
[01:33] <len_1304> For this experiment Jack is running at -p 512 for 23 ms latency.
[01:34] <len_1304> jack 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.
[01:38] <len_1304> Pulse 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.
[01:41] <len_1304> At 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.
[01:42] <len_1304> for this reason I am running rate of 44100.
[01:43] <len_1304> Opening 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.
[01:47] <len_1304> The 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.
[01:49] <len_1304> If 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.
[01:58] <len_1304> Lumpy, this set up would require more cpu horse power than I have. I do not know if two cores would be enough or not.
[02:06] <len_1304> The phone on gmail is much better but the latency is up around .5 or more sec.
[02:30] <len_1304> Nope I got it wrong, streaming takes 30% cpu. The player doesnt take that much unless the rate is different from jack.
[04:23] <shai_halud> holstein: earlier you mentioned something about a wav to midi program. what is the phg name i need to look for?
[04:23] <shai_halud> er pkg
[04:24] <holstein> http://stackoverflow.com/questions/5852102/software-to-convert-audio-to-midi ?
[04:51] <shai_halud> that must be it. installing kxstudio, btw
[04:51] <shai_halud> er, doing the updates from that repo. 500 megs worth
[04:52] <holstein> i havent added them yet
[04:52] <holstein> but i might...
[04:54] <shai_halud> that was just the updates. now i'm going for the kxstudio packages, THEN the mutltimedia software. this must be a few gigs altogether or something
[04:55] <shai_halud> pkgs are 173 megs
[04:56] <shai_halud> probably 1 gig at the end of the day
[04:56] <shai_halud> aha there he is
[04:56] <shai_halud> hey whippersnapper
[04:57] <shai_halud> sirriffsalot: talking to you....
[04:57] <sirriffsalot> What?
[04:57] <shai_halud> almost done installing kxstudio
[04:57] <sirriffsalot> Rofl
[04:58] <sirriffsalot> Hahahah
[04:58] <sirriffsalot> You're such a slut
[04:58] <shai_halud> whoa
[04:58] <shai_halud> kinds keep that to yourself, eh?
[04:58] <sirriffsalot> A joke ofc
[04:58] <sirriffsalot> Why are you going for kxstudio already?
[04:59] <sirriffsalot> I mentioned it an hour ago and you're reverting.. Without even getting ardour and jack worked out in Ubuntu Studio??
[04:59] <sirriffsalot> A little rushy for me anyway
[05:05] <shai_halud> holy cow. this .... changed my entire DE
[05:05] <shai_halud> without a reboot
[05:09] <shai_halud> well. i'm in this far. might as well go for broke
[08:17] <mick_> hello?
[08:17] <smartboyhw> Hello mick_
[08:17] <mick_> hey, hows things
[08:18] <mick_> i have a problem with getting a us122 (old) to work with usb, it works sometimes, then it fails
[08:20] <mick_> can anyone help?
[08:21] <mick_> or at least suggest an upgrade?
[08:35] <sirriffsalot> mick_: Us122?
[08:36] <mick_> yes its a tascam external sound card
[09:50] <mick_> what is a good interface to use with studio?
[10:43] <mick_> Can someone give me some clues as to which sound card I should consider?
[10:55] <shai_halud> greetings!
[10:59] <zequence> mick_: https://help.ubuntu.com/community/UbuntuStudio/SupportedHardware
[11:00] <mick_> Thank you :)
[11:00] <zequence> mick_: http://wiki.linuxmusicians.com/doku.php?id=hardware_matrix
[11:00] <shai_halud> hi Zeke
[11:02] <zequence> shai_halud: Hi. I was wondering who Zeke was :)
[11:03] <shai_halud> haha
[11:03] <shai_halud> that's YOU
[11:03] <shai_halud> are you terribly busy?
[11:05] <shai_halud> i 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 mean
[11:05] <zequence> shai_halud: shoot
[11:05] <shai_halud> one sec
[11:06] <shai_halud> http://pastebin.ca/2327606
[11:06] <zequence> shai_halud: I would recommend #lad and #opensourcemusicians also. Many of the application developers hang out at #lad
[11:06] <shai_halud> ok
[11:09] <zequence> shai_halud: Did you do this? "after installing missing packages, remove CMakeCache.txt before"
[11:09] <shai_halud> every time
[11:09] <zequence> Ok, just checking
[11:10] <shai_halud> (about 20-30 times)
[11:10] <shai_halud> i exaggerate slightly
[11:10] <zequence> shai_halud: Oh, try this btw. sudo apt-get build-dep lmms
[11:11] <zequence> That'll install all build dependencies
[11:11] <shai_halud> SWEET
[11:11] <shai_halud> that's what i was wishing existed
[11:11] <zequence> Yeah, it's handy
[11:13] <shai_halud> Only 31 megs to dl
[11:13] <shai_halud> wheeee
[11:15] <shai_halud> ok. i think cmake got far enough that time
[11:16] <shai_halud> Looking for pthread_create in pthreads - not found
[11:16] <shai_halud>     and QS_WIN also
[11:16] <shai_halud> process.h
[11:16] <shai_halud> seems nothing fatal
[11:17] <shai_halud> oh, and this:
[11:17] <shai_halud> ooking for include file /usr/src/sys/gnu/i386/isa/sound/awe_voice.h
[11:19] <shai_halud> woohoo. running make
[11:24] <zequence> shai_halud: Why are you building lmms, btw?
[11:24] <shai_halud> because i couldn't find a precompiled version of 4.13
[11:24] <zequence> Ok
[11:24] <zequence> could be kxstudio repos have it
[11:24] <shai_halud> nope
[11:25] <shai_halud> i am compiling theirs now
[11:25] <shai_halud> LMMS website is same
[11:26] <shai_halud> i figured ksstudio might be a little beefier. it is 1 meg larger
[11:26] <shai_halud> 80% make, no errors
[11:27] <shai_halud> 2 erros
[11:27] <shai_halud>  i wonder what they are
[11:28] <shai_halud> wine errors
[11:28] <zequence> 64bit might not work with wine
[11:29] <shai_halud> ok make install finished. now to see what it made
[11:33] <shai_halud> crap . it has no presets
[11:34] <shai_halud> hm
[11:34] <shai_halud> everything else seems fine
[11:36] <zequence> shai_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 with
[11:37] <shai_halud> i certainly would, if i am able
[11:37] <shai_halud> though i'm afraid my skills are rather meager.
[11:37] <zequence> shai_halud: Check out the wiki https://wiki.ubuntu.com/UbuntuStudio/
[11:38] <shai_halud> if there are ways I can help, I will glady do so
[11:38] <zequence> We don't need skills. Only will in most cases :)
[11:38] <zequence> we hang out at #ubuntustudio-devel
[11:39] <shai_halud> well, will i have in plenty
[11:39] <zequence> shai_halud: This is our team structure https://wiki.ubuntu.com/UbuntuStudio/TeamStructure
[11:39] <zequence> As you might notice, we have more teams than members
[11:40] <shai_halud> and if there are opportunities for me to learn, EXCELSIOR!
[11:40] <shai_halud> hehe
[11:40] <zequence> The teams are not only categories for splitting up responsibilities. We work with launchpad a lot, and each team is also a launchpad team
[11:40] <zequence> It has some benefits doin it that way
[11:41] <zequence> shai_halud: If you haven't got a launchpad account, get one. https://launchpad.net/
[11:41] <shai_halud> k
[11:41] <shai_halud> on it
[11:41] <zequence> you could begin by joining https://launchpad.net/~ubuntustudio
[11:42] <zequence> But, from there, it's really up to what you'd be interested in doing
[11:42] <zequence> shai_halud: join #ubuntustudio-devel, and I'll talk more
[11:42] <shai_halud> ok
[11:42] <shai_halud> gimme 5 to reggy
[11:46] <mick_> ok ill bite, got anything that will take around 20 mins of my time per day?
[11:46] <mick_> maybe more
[11:47] <zequence> mick_: 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 lot
[11:48] <zequence> testing for instance is not very structure right now. It should be, and we need to make it so in the future
[11:48] <zequence> We need a vivid PR team, who posts stuff on mail lists, our website and social channels
[11:49] <mick_> hmm
[11:49] <zequence> We 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 job
[11:50] <zequence> Right now, we have too few people working on too many things.
[11:50] <zequence> Software development, and handling Ubuntu Studio source is not the biggest part of what we do
[11:50] <zequence> We have our own kernel, and right now, I'm the maintainer of it.
[11:51] <zequence> I will want for more people to learn that stuff too, and am preparing documentation
[11:51] <zequence> Oh, yeah. we need people who write docs too
[11:53] <zequence> mick_: The team structure let's you know what areas we work in https://wiki.ubuntu.com/UbuntuStudio/TeamStructure
[11:53] <zequence> mick_: shai_halud: blueprints is where we organize what we work on, who works on what, etc https://wiki.ubuntu.com/UbuntuStudio/PermanentBlueprintOverview
[11:54] <shai_halud> all pages bookmarked
[11:54] <zequence> All of the blueprints are at launchpad, so that is just an overview
[11:54] <zequence> shai_halud: I've been making sure everything you need is avaible from the wiki, so shouldn't be hard to find stuff
[11:54] <shai_halud> k
[11:55] <zequence> The important sources of info are really: blueprints, IRC and mail lists
[11:56] <zequence> some 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 teams
[11:57] <zequence> So, the first step is: become a member of launcpad. login to #ubuntustudio-devel, and subscribe to at least the Ubuntu-Studio-devel mail list
[11:57] <shai_halud> i'm in the channel now
[11:57] <zequence> mick_: You're welcome too
[11:57] <shai_halud> and perusing for the mail list
[12:03] <mick_> what was that link again I clicked on it and got lost, the getting started link
[12:04] <zequence> mick_: You have all the info from here https://wiki.ubuntu.com/UbuntuStudio
[12:04] <zequence> Next to the orange developer section
[12:04] <mick_> thanks
[12:04] <zequence> mick_: login to #ubuntustudio-devel
[12:04] <mick_> ty
[12:05] <zequence> mick_: I'm going away for a little while, but maybe someone else can answer any questions you have
[12:05] <zequence> bb in 30 or so
[12:05] <mick_> ok, ill see what i can find
[12:35] <zequence> mick_: why don't you join #ubuntustudio-devel too. I'm just talking with shai_halud there
[12:36] <mick_> join #ubuntustudio-devel
[12:36] <mick_> woops
[13:06] <studio-user992> bheey
[18:40] <iorec> helos, is there an easy way to upgrade from ubuntu to ubuntustudio without a complete reinstall?
[18:44] <Unit193> You can install the metapackage(s)
[18:45] <iorec> how would i go about doing that?
[18:46] <Unit193> You could install ubuntustudio-desktop, but they have several others as well, apt-cache search ubuntustudio   to see all.
[18:47] <iorec> and thats the full ubuntustudio "experience" then or just a hack?
[18:50] <zequence> iorec: 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 ISO
[18:50] <Unit193> It's how you'd go from one to the other.  However, you will have "leftover" applications you may not need.
[18:51] <zequence> There may also be some conflicts in user settings, if you have many desktop systems installed in paralell
[18:51] <zequence> If you don't need the desktop, just install the packages you want
[18:51] <iorec> k, 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] <zequence> To get realtime privilege, you'll need to add yourself to audiog group
[18:51] <zequence> To get low latency, install linux-lowlatency
[18:52] <zequence> iorec: That's a bug
[18:52] <zequence> iorec: It crashes sometimes when you try to stop it
[18:52] <iorec> ja, probably..at the moment it just won't start anymore.
[18:52] <zequence> To kill it, do: killall -9 jackdbus
[18:52] <zequence> It's probably frozen in the background
[18:52] <iorec> starts with built-in soundcard, but no more with external usb-audio device
[18:53] <zequence> And, also, it might not start, if pulseaudio is using the same device for something
[18:53] <zequence> That's also a bug, btw
[18:53] <iorec> i had pulseaudio killed completely..didn't change anything.
[18:54] <iorec> also several restarts of usb-device and pc didn't help
[18:54] <iorec> will try the killall -9 jackdbus
[18:54] <zequence> How did you kill pulseaudio?
[18:54] <iorec> how to start it then?
[18:54] <zequence> How to start jackdbus?
[18:55] <zequence> Either with qjackctl, using the default settings, or from a command line: jack_control start
[18:55] <iorec> found 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] <iorec> k, i have qjackctl
[18:55] <zequence> And each time, the onboard would work?
[18:55] <iorec> jes onboard works
[18:56] <zequence> what does this show you? cat .jackdrc
[18:56] <zequence> That should be: cat ~/.jackdrc
[18:56] <zequence> Mine is: /usr/bin/jackd -dalsa -dhw:M66 -r44100 -p1024 -n2
[18:57] <HelloWorld321> this 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] <zequence> HelloWorld321: Sorry. Don't know what that is
[18:59] <iorec> this i get: /usr/bin/jackd -v -P1 -dalsa -dhw:0 -r44100 -p1024 -n2 -Xseq
[18:59] <HelloWorld321> zequence: tx.
[18:59] <HelloWorld321> If 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 extension
[19:00] <HelloWorld321> I think in a normal installation, they would have no extension; but I've accidentally renamed some to .eml
[19:02] <zequence> iorec: Well, it's not too low buffer anyway.
[19:02] <zequence> iorec: Which device is it?
[19:03] <iorec> maudio quattro
[19:03] <iorec> first error i get on starting: ERROR: Cannot lock down 82241434 byte memory area (Cannot allocate memory)
[19:03] <iorec> then it goes on
[19:03] <iorec> next errro: RROR: ALSA: could not start playback (Broken pipe)
[19:04] <zequence> iorec: The memory error would indicate you don't have realtime privilege
[19:04] <iorec> mkay, but why? since when?
[19:04] <zequence> iorec: Check if you're in audio group: groups
[19:04] <iorec> how can i check that?
[19:05] <zequence> Use the command "group" and see if "audio" is one of the results
[19:05] <zequence> groups
[19:05] <zequence> ..I mean
[19:06] <iorec> nope. apparently i am not in the audio group
[19:07] <iorec> how can i get an invite there?
[19:07] <zequence> iorec: 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 that
[19:07] <zequence> iorec: sudo usermod -a -G audio $USER
[19:07] <zequence> The file for groups is in /etc/group
[19:07] <zequence> You can also edit it manually
[19:08] <iorec> i only uses 2 i/o's (haven't tried 4 at all)
[19:08] <zequence> On Debian, from where jack is imported, users are already members of audio group
[19:08] <iorec> *used
[19:08] <zequence> iorec: So, do you specify that in qjackctl settings?
[19:08] <iorec> yes
[19:09] <zequence> ok, well. I've tried using the quattro, only quickly, and even though it started, I got static, just cause I didn't specify I/O
[19:09] <zequence> anyway..
[19:09] <iorec> it worked for me.on and off..
[19:10] <zequence> Something that I've heard a lot is that using a Periods/Buffer of 3 is better for some usb devices
[19:10] <zequence> But, that would probably not help
[19:11] <zequence> iorec: Does it work at all with pulseaudio?
[19:11] <iorec> k, will now try to get me in that audiogroup
[19:11] <iorec> not sure about pulseaudio..
[19:11] <zequence> iorec: You'll need to log out and in again for that change to take effect
[19:12] <iorec> ok. now also waiting for the ubuntu 12.10 update to finish
[19:18] <zequence> iorec: So, whenever you try starting jackdbus, if it told you it could stop, make sure to kill it before attempting again
[19:18] <zequence> iorec: No PPAs, btw?
[19:18] <zequence> ..couldn't stop the, the previous time you tried to stop it, I mean
[19:19] <iorec> PPAs`
[19:19] <iorec> ?
[19:19] <zequence> !PPA
[19:19] <zequence> I'm getting a little tired. Been writing Wiki pages the whole day
[19:19] <iorec> you're asking if i am using one?
[19:19] <zequence> iorec: Yes
[19:20] <iorec> ok, guess not then...since i wasn't aware of them
[19:20] <iorec> well anyway thanks for your help sofar
