_pg_i missed the mtg yesterday. is it logged somewhere?16:03
_pg_or can i get a cliffnotes lol16:03
tertl3_i have failed to get any sound levels with jack  :(16:10
tertl3_anyone happen to know why?16:11
holsteinmorning tertl3_16:15
tertl3_good morning16:16
holsteinSO whats up with JACK?16:16
holsteinare you using your insternal sound card?16:16
tertl3_its PCI soundblaster16:17
holsteinOK16:17
tertl3_i have got the PC to recognize it with alsa16:17
holsteinwhat do you mean by 'no levels'?16:17
tertl3_well, like when I try to use ardour or a guitar effect software, I get no levels16:18
astraljava_pg_: Might be here: http://irclogs.ubuntu.com/2010/05/16/%23ubuntustudio-devel.html16:18
tertl3_it could be that I dont have the connections right, but I have tried many different ways16:18
holsteintertl3_: OK16:20
holsteinlets start at the beginning16:20
holsteinyou hear sound otherwise with the card right?16:20
holsteinwith pulse or whatever?16:20
tertl3_yes16:20
tertl3_and I can record with audacity as long as i dont use jack16:21
holsteinwhen you start JACK, do you use qjackctl?16:21
tertl3_i use the the gui tab, but yes16:21
holsteinOK16:21
holsteinso your looking at qjack when you start jack16:21
holsteinany errors?16:21
holsteinor does it just start?16:22
holsteindo you see any xruns?16:22
tertl3_xruns?16:22
tertl3_i have jack on my other parition, b/c of issues with the RT kernel, so I might need to boot into it so I can run it and tell you what happens16:23
holsteinhttp://www.passback.org.uk/music/fedora-music-intro/16:24
tertl3_i am using ubuntu16:24
tertl3_:)16:24
holsteinyeah16:24
holsteinthis is just a pic of qjack16:25
tertl3_oh16:25
tertl3_my mistake16:25
holsteinthe first pic16:25
holsteinthats the main qjackctl window16:25
holsteinthats where you'll see xruns16:25
tertl3_when it runs, it says either started or active16:26
holsteinOK16:26
tertl3_and when I hit record it says rolling16:26
holsteinin ardour?16:26
tertl3_and its usually at about .67%16:26
tertl3_yes, in ardour16:26
holsteinSO you've never heard any sound from JACK16:27
holsteinOR with JACK ?16:27
tertl3_well, the sound comes out of the speakers, but I get no indication from ardour or jack16:28
holsteinOH16:28
holsteinwell, that might be fine then16:28
tertl3_yea, I've been fighting with this for 2 days :)16:29
holsteinwhat indication do you want?16:29
holsteina meter?16:29
holsteinjack won't give you a meter16:29
holsteinit will just list the devices you can 'jack'16:30
tertl3_yeah, like when I play the guitar, ardour doesnt give the levels16:30
tertl3_I know, but I jacked it to ardour16:30
holsteinOK16:30
holsteini think it could be a 'track arming' thing16:31
holsteinin arour16:31
holsteinyou create a track16:31
holsteinardour*16:31
tertl3_ok16:31
tertl3_I did that16:31
holsteinassuming you have the routing done properly16:31
holsteinyou hit the record button on that track16:32
holsteinand the meter should show the 'in'16:32
holsteinyou can also open the mixer in ardour16:32
holsteintheres a button16:32
holsteinat the bottom of the channels16:32
holsteintoggles between what the meter indicates16:33
holsteinususally the defauly behavior works fine16:33
holsteinBUT occasionally i have to change those manually16:33
tertl3_ok, I will boot to other partition and try it.   I will go to IRC there16:34
holsteincool16:34
holstein:)16:34
tertl3ok, I made it16:38
* holstein too16:39
holsteini got my mininote with lucid studio fired up :)16:39
tertl3cool16:39
tertl3how should the routing look on th alsa tab?16:40
holsteinyou just need to make sure you choose the proper 'in'16:41
holsteinfrom your sound card16:41
holsteinand  route that to the channel input in ardour16:42
holsteineverything else is probably set up by default16:42
holsteinBUT i always look over it anyways16:42
holsteinyou can just run ALL you soundcard inputs into the channel16:42
tertl3ok16:43
holsteinto make sure you got it16:43
holsteinAND you can unplug them one at a time16:43
holsteinassuming you have more than 1 or 2 showing up16:43
holsteinyou probably only have the right and left from te line-in or something like that16:43
holsteinhttp://imagebin.org/index.php?page=add16:44
holsteini think we can use this for screemshots16:45
holsteinscreen*16:45
holsteinoops...16:45
holsteinmelt-down?16:46
tertl3yeah, jack froze up16:47
holsteinhmmm16:47
holsteinhow so?16:47
tertl3it kept fading dark and not responding16:47
holsteinwhat are your settings?16:47
holsteinhttp://www.passback.org.uk/music/fedora-music-intro/16:48
holsteinthe 4th image down16:48
holsteinyour frames/periods and periods/buffer settings16:49
tertl3ok, oe sec16:49
holsteinyou could just take a screenshot if you want16:49
tertl3trying to get alsa working16:49
tertl3now, jack is screwing up again16:51
tertl3idk, I'll have to come back to it16:51
tertl3ok frames/period is 12816:56
holsteintertl3: OK16:56
holsteinfor now16:56
holsteinlets change that to 51216:57
holsteinand periods/buffers16:57
tertl3ok16:57
holsteinlets try and set tat at 316:57
holsteinthat*16:57
tertl3ok, just changed it16:58
holsteinand for latency at the bottom right?16:58
holsteinwhat does that say now?16:58
tertl332 msec16:58
holsteincool16:58
holsteinand the realtime checkbox?16:58
holsteinis that checked?16:58
tertl3yes, its checked16:59
holsteinOK lest see if that lets JACK run more stable16:59
holsteinwith these settings16:59
holsteinsample rate?16:59
holstein44.1?16:59
tertl3ok, its runinng good,17:00
holsteinOK17:00
tertl3.51    .467   .444   .43917:00
holsteinthe soundblaster gear is not 'pro' level gear in my opinion17:00
holsteinas far as getting into the computer at least17:00
holsteinANYWAYS17:01
tertl3yeah, I bought it more for output, but it says its 24 bit17:01
holsteintry routing you a channel now17:01
tertl3ok, what do you mean routing a channel?17:01
holsteinlike, try firing up ardour17:02
holsteinand route the line-in17:02
holsteinsee if it works17:02
tertl3oh17:02
tertl3ok, got a channel up, but I am not getting a reading17:03
tertl3could sometihng the blocking it or do i need  to configure ardour?17:04
holstein...3 minutes.. BB17:04
holsteinhmmm17:07
holsteintertl3: SO, did you route all the possible out's to your ardour channel?17:08
tertl3i'm not sure how to do that17:08
tertl3i've got a small blue reading from the ardour mixer17:09
holsteinhttp://qjackctl.sourceforge.net/qjackctl-ss1.html17:09
holsteintertl3: OH17:09
holsteinwhats the small blue reading?17:10
tertl3but no repsonse17:10
holsteinmaybe its just a low-level17:10
tertl3its like it recogizes an input, but when I play it doesn't move17:10
holsteinOK17:10
holsteinlets use zynaddsubfx17:11
holsteinstart that up17:11
tertl3ok17:11
tertl3its up17:12
tertl3should i have anyithng connected on the ALSA tab of jack?17:12
* holstein looking17:12
holsteinin zyn17:12
holsteingo to the 'instrument' tab17:13
tertl3open?17:13
holsteinand open the 'virtual keyboard17:13
holstein'17:13
tertl3dont see it17:14
holsteinOK17:15
holsteingoto the 'misc' tab17:15
holsteinand change the interface to 'advanced'17:15
holstein'switch user interface mode17:15
holstein'17:15
tertl3ok, I was gonna sak about that when I opened it, but ok the keyborad is up17:16
holsteinwhen you play a note17:17
holsteinwith the ouse17:17
holsteinmouse*17:17
holsteindo you hear it?17:17
tertl3no, but I am geting a reading from ardour now17:17
holsteinOK17:18
holsteinSO17:18
tertl3thats improvement17:18
holsteinlook at you 'audio' tab17:18
holsteinyour*17:18
holsteinin 'connections17:18
holstein'17:18
tertl3yes17:18
holsteinzyn has 2 outs17:18
holsteinwhere are those going?17:19
tertl3one to ardour, and one to system17:19
holsteinOK17:19
holsteinexpand all that17:19
holsteinthe little plus signs17:19
tertl3ok, one to master/in 1 and one to palyback 1 and one to playback 217:20
holsteinOK17:20
holsteinplayback 1 and 217:20
holsteinthose should be your speakers17:20
holsteinyour 'monitor' out17:20
holsteinyou should be hearing zyn17:21
holsteinBUT anyways17:21
holsteinyou got the meter moving in ardour17:21
holsteinand that makes me think the line level is just not hot enough17:21
holsteinOR some routing is incorrect17:21
holsteinBUT i think its the level17:22
holsteindo you have a mixer?17:22
tertl3no17:22
holsteinsomething with a preamp?17:22
tertl3I wish i did17:22
tertl3my bass amp17:22
holsteinyou could try it17:22
tertl3thats what i play guitar through17:22
holsteinyou need something to bump the signal up17:22
holsteinon the way in17:23
tertl3yeah, it goes out of the preamp out17:23
tertl3into the PC17:23
holsteinwell, turn it up to 11 ;)17:23

holsteini got no idea about how to straiten it out though :/17:33
tjingboemit takes 30 seconds after logging in for my system to be operational17:33

holsteini havent gotten very far in troubleshooting yet though17:36
tjingboemdoes it takes a lot of time too?17:36
holsteini say about 30 seconds more than i think it should17:36
tjingboemah, same thing perhaps17:36
holsteinits doing it on 2 boxes17:36
tjingboemi can not compare it to Ubuntu itself, i have only UbuntuStudio installed17:37
holsteinshouldnt matter really17:37
holsteinfor the basics under the hood17:38
tjingboemi will try elsewhere, but i find that when there are too mayny people my question remain unnoticed17:38

abstrakthey19:12
abstraktbig problems with Ubuntu 10.04 amd64 and realtime kernel :/19:12
tertl3yes19:12
tertl3i have same problems19:13
abstraktdang19:13
tertl3is jack working for you?19:13
abstrakttertl3, freeze -> (initramfs) prompt?19:13
abstrakttertl3, well, it was for a while this last time19:13
abstrakti've reinstalled twice now19:13
abstraktthis latest time the crash happened right when i hit start on qjackctl19:13
tertl3well, its bad news, but I am glad its not just an operator error for me  :)19:14
abstraktyeah me too :(19:14
abstraktbut still19:14
abstraktthat really sucks19:14
abstrakt64 bit was so much better19:14
tertl3i have done dual boot and one partition with a rt19:14
abstrakti have a dual boot but win/nix19:15
tertl3well, this was my first real attempt at using jack, but I cant seem to get any sound out of it19:15
abstraktand if the rt partition crashes and burns like that all the time, that's basically useless19:15
abstrakttertl3, there's #jack btw19:15
tertl3yeah, I'm in there :)19:15
tertl3so you dont get jack to run at all on RT kernel?19:16
tertl3did you go here     https://help.ubuntu.com/community/UbuntuStudioPreparation19:18
abstrakttertl3, no not yet19:19
abstrakttertl3, "The web page is not available"19:20
holstein??19:20
holsteinworks for me19:20
holsteinyou can also try sudo qjackctl19:20
holsteinmake sure its not a permissions issue19:20
abstrakttertl3, yeah i was going to suggest trying to run qjackctl as root19:21
abstrakttertl3, if that works then you just probably haven't edited your /etc/system/limits.conf19:21
abstrakttertl3, you need to give your audio group "realtime priority" in order to run qjackctl as a normal user19:22
tertl3how?19:22
holsteinits all in https://help.ubuntu.com/community/UbuntuStudioPreparation19:22
holsteinhttps://help.ubuntu.com/community/UbuntuStudioPreparation19:23
holsteinooos19:23
holsteinsudo su -c 'echo @audio - rtprio 99 >> /etc/security/limits.conf'19:23
holsteinsudo su -c 'echo @audio - memlock unlimited >> /etc/security/limits.conf'19:23
abstraktyeah that's the bit19:23
holsteinlooks like that19:23
abstraktseems like it should be using tee instead but whatever works19:23
holsteintheres a package for it too now19:23
holsteina gui19:23
abstrakta package for limits.conf ?19:24
holsteinin the admin tab i think19:24
abstraktadmin tab of what19:24
holsteinlucid19:24
holsteinstudio19:24
abstraktholstein, er... tab?19:24
abstraktholstein, you mean menu?19:24
abstraktholstein, any thoughts on my initramfs freeze?19:25
holsteinsystem > administration > ubuntu studio settings19:25
holsteinor something like that19:25
* holstein is not in front of it right now19:25
holsteinabstrakt: do you have to have the RT kernel?19:25
abstraktholstein, yup19:25
holsteinhave you tried the generic one?19:26
abstraktholstein, that's specifically what i need19:26
holsteinhmmm19:26
abstraktneed the low latency for audio recording19:26
holsteinmabe just use the 32bit version?19:26
* holstein hasnt used the 64bit install yet19:26
abstraktholstein, that's specifically why i installed 64 bit though, 32 bit just wasn't fast enough19:26
abstraktand was crashing a bunch19:26
abstraktwell, now i guess it's faster *and* it's crashing a bunch19:27
abstraktonly primary difference is now this crash does NOT seem recoverable19:27
abstrakti get stuck at a prompt that says (initramfs)19:27
tertl3holstien: that command said unknown ID19:27
holsteintertl3: ??19:28
abstrakttertl3, just edit the file by hand and add those lines19:28
abstrakttertl3, sudo nano /etc/security/limits.conf19:28
abstrakttertl3, pico nano /etc/security/limits.conf19:28
abstrakttertl3, vim nano /etc/security/limits.conf19:28
abstrakti dunno what comes with ubuntu19:28
abstraktactually i know vim does but i don't know about nano or pico19:28
holsteinsudo gedit /etc/security/limits.conf19:29
holsteingedit FTW ;)19:29
abstraktnah, vim ftw :)19:29
holsteinhehe19:29
abstraktgvim ftw actually19:29
holsteini can get around OK in nano19:30
abstraktbut vim would probably beat the crap out of tertl3 and he'd come crying back19:30
holsteinwhen i run vim, i need a google page open somewhere for reference ;)19:30
abstraktlol that's like saying i can get around ok in my front yard19:31
abstraktlol19:31
holsteinand i can19:31
tertl3yeah, i tried vim once19:31
tertl3its overly complex19:31
holsteini have a server install19:31
holsteinan i did the config in vim19:31
tertl3or either a exponential learning curve19:31
holsteinBUT i forgot it all right after19:32
abstraktholstein, you mean like one of these? http://www.viemu.com/vi-vim-cheat-sheet.gif19:32
holsteini would have to do it more often to keep my chops up19:32
holsteinabstrakt: thats a good one19:32
abstrakttertl3, it's neither actually, but it all depends on what you need to do, if you are an author, like a writer, you probably want emacs, if you're a programmer you probably want vim19:32
abstraktholstein, yeh print that baby out and put it on ur desk19:32
abstraktholstein, then you don't need google :)19:32
holsteinw00t19:33
abstrakttertl3, if you don't code then you won't understand why vim is neither overly complex nor exponential to learn19:33
abstraktoh well19:33
abstraktbubbye then19:33
tertl3when I choose between kernels at grub, it keeps everything else the same, and only changes the kernel?20:15
tertl3it that how it works?20:15
holsteinyup20:16
holsteinyou can just choose between them20:16
holsteinyou could find a device that is not supported in one that is supported in the other20:16
holsteinBUT probably not20:16
tertl3cool20:17
* tertl3 stcks with audacity and alsa for now20:17
tertl3my RT kernel is running fine now20:17
holsteinthats a good place to start20:18
holsteini always say, just start simple, and move up when you hit a wall and need something20:18
tertl3yeah, only thing I really need jack for is to play with the effects20:19
tertl3but, that can be badly distracting20:20
holsteinwhen you need it, you'll know :)20:20
tertl3nothing wrong with clean guitar i suppose20:21
tertl3alsa, I have a couple of pedals  :)20:21
tertl3do you ever put effects on your upright for fun?20:22
* tertl3 takes a pinch of snuff20:23
tertl3after all, I think you get more recognition for sounding good without a lot of effects when playing a traditional instrument20:28
holsteintertl3: i use rakarrack onthe upright some20:30
holsteinit has a MIDI function too20:30
holsteinthat project is awesome20:30
holsteinthose guys hang in #opensourcemusicians20:30
holsteintransmorofix i think20:30
holsteini want to say hes the main dev20:31
holsteinANYHOW20:31
holsteinthe MIDI is a little slow20:31
holsteinbut i can use the bass to trigger a synth pad20:31
holsteinand run it through effects or whatever20:31
holsteinvery cool20:31
tertl3thats neat20:31
holsteinthe latest 'testing' rakarrack has a looper too20:32
tertl3dang, i really do need that  :)20:33
tertl3theres got to be something I;m not doing properly for jack not play the sound20:33
holsteinJACK doesnt have to support your audio device20:36
holsteincould be that simple20:36
holsteinyou'll want something else anyway20:36
holsteinif your going to do something in the 'pro' realm20:36
holsteinsomething with balanced in's, or preamps20:37
holsteinif your shopping on the 'cheap'20:37
holsteinhttp://www.bhphotovideo.com/c/product/422094-REG/Behringer_UCA202_UCA202_USB_Audio_Interface.html20:37
holsteinthat works well20:37
holsteinjust no preamps, or balanced in's20:37
tertl3hmm20:39
tertl3i guess I could look up that list for jack supported cards20:40
tertl3but, would i get sound when jack is on if jack didnt support my card?20:44
holsteintertl3: probably not20:50
holsteinif its not supported, it could partially work20:50
holsteinOR just be strange i guess20:50
holsteinim not a big fan of USB interfaces20:51
holsteinBUT its nice to be able to use the same interface easily with laptops and desktops20:52
tertl3thats a nice and simple card22:54
tertl3is the USB not slow?22:55
tertl3i guess low latency answers that qustion22:56
