[05:02] <benhem> hi, I am pretty set on embarking on an upgrade from ubuntu 10.11 to ubuntustudio 10.11 ... I'm reading this document:
[05:02] <benhem> https://help.ubuntu.com/community/Ubuntu%20Studio%20Upgrade%20from%20Ubuntu
[05:02] <benhem> it says "warning, contents under construction" -- I don't want to risk lousing this all up -- are there any specific things anyone can tell me to look out for?
[05:02] <benhem> thank
[05:02] <benhem> *thanks
[05:04] <holstein> benhem: i would start like this... what do you want to do?
[05:04] <holstein> you dont need any of the ubuntustudio stuff
[05:04] <holstein> you can open a pacakge manger, synaptic, or the software center and search 'ubuntustudio'
[05:04] <holstein> you'll see all the metapackages
[05:04] <holstein> there are a few that are just for the look and feel
[05:04] <benhem> I want a realtime kernel for midi recording, mostly, but the rest sounds pretty cool too
[05:05] <holstein> benhem: we dont have a kernel RT anymore
[05:05] <holstein> its not in debian upstream
[05:05] <holstein> and you dont need anything from ubuntustudio to have a kernel RT
[05:05] <benhem> ergh, what option does that leave me?  I couldn't find a way to install a low latency, preempt, or realtime kernel on 10.11
[05:05] <holstein> https://launchpad.net/~abogani/+archive/ppa
[05:05] <holstein> benhem: i urge you to try the generic
[05:05] <holstein> then the lowlatency
[05:05] <holstein> then the RT
[05:05] <benhem> well, I'm on generic now, can't figure out how I'd try the others
[05:06] <holstein> we are finding most dont need the RT kenrel anymore
[05:06] <benhem> generic stutters and drops stuff
[05:06] <holstein> benhem: you add that PPA i linked
[05:06] <benhem> *might* be a botched jack setup though
[05:06] <holstein> it has the kernels
[05:06] <holstein> benhem: you can try starting things as root *to test*
[05:06] <benhem> oh, ok
[05:06] <holstein> and see if its permission
[05:06] <holstein> s
[05:06] <holstein> benhem: we wont have, or need to have a kernel RT much longer
[05:07] <holstein> benhem: you can ask around in #opensourcemusicians
[05:07] <holstein> lots of MIDI guys there
[05:07] <benhem> ok, thanks
[05:07] <holstein> im using a realtime kernel in ubuntu 10.04
[05:07] <holstein> the one from the kxstudio ppa's
[05:08] <holstein> benhem: also, if you are using an internal soundcard, and you are getting around 20ms latency, thats quite good
[05:09] <benhem> I am really confused about the latency and the jack setup
[05:09] <holstein> even something like this http://www.behringer.com/EN/Products/UCA202.aspx can really step things up
[05:09] <benhem> it says "latency, 21.3 msec" with my current settings: 128frames/period, 48000 sample rate, 8 periods/buffer
[05:09] <holstein> benhem: yup
[05:09] <benhem> but it still hiccups and drops stuff
[05:09] <holstein> if thats an internal sound card, thats great
[05:10] <holstein> you can check that 48000 is what your card likes
[05:10] <holstein> the frames/period and periods/buffer are what we tweak
[05:10] <benhem> ok, looking up stats on my sound card
[05:11] <holstein> you want to try 2 periods/buffer and 512 frames/period
[05:11] <holstein> thats a good place to start
[05:11] <benhem> ok
[05:11] <holstein> then, go to 256 frames/period
[05:11] <holstein> 48000 is usually OK
[05:11] <benhem> 512/2 leaves me with the same latency, 21.3
[05:11] <benhem> trying it out
[05:11] <holstein> benhem: is it an internal sound card?
[05:12] <benhem> yep, everything is stock
[05:12] <benhem> just a laptop
[05:12] <holstein> benhem: that card i linked is like $30 us
[05:12] <benhem> huh, ok
[05:12] <holstein> you can ask around in #opensourcemusians
[05:12] <holstein> other folks use that card
[05:12] <holstein> benhem: you'll *never* get the performance you want out of that card
[05:16] <benhem> the internal one in my laptop?
[05:16] <holstein> benhem: right
[05:16] <benhem> hmm, my old setup with ubuntu 9 worked well
[05:17] <holstein> benhem: yeah?
[05:17] <holstein> benhem: install that then
[05:17] <benhem> I don't know what the key differences were
[05:17] <holstein> benhem: systems evolve
[05:17] <holstein> kernels change
[05:17] <benhem> I'm tempted
[05:17] <holstein> you dont want to use that internal card
[05:17] <benhem> but I was hoping that ubuntu-studio would be a sort of sideways migration that would achieve the same ends
[05:17] <holstein> that'll be the best 3 bucks you ever spent
[05:17] <benhem> (and I wouldn't have to mess with backing up my data)
[05:17] <benhem> ok, I'll check out the card, thanks for that
[05:17] <holstein> benhem: nah
[05:18] <holstein> ubuntustudio *is* ubuntu
[05:18] <holstein> benhem: you can try AVlinux live
[05:18] <holstein> theres a new dynebolic live CD
[05:18] <holstein> still.. *no* studio uses internal sound cards
[05:20] <holstein> also, you might not need low latency
[05:20] <holstein> depends on what you are doing
[05:20] <benhem> I'm beginning to wonder if my real problem is latency or not
[05:20] <holstein> i typically mix and track at like 60+ms
[05:20] <holstein> i have different JACK profiles
[05:20] <benhem> because the problem is a stutter where it drops a full half-second of input
[05:20] <holstein> i can do 1.2ms stable
[05:20] <holstein> but i rarely need to
[05:21] <holstein> if im playing something in live, and i want realtime effects at the time in tracking
[05:21] <holstein> or im using a MIDI instrument
[05:21] <holstein> otherwise.. who cares if when i push play, it takes 60ms to come out the speakers...
[05:22] <holstein> benhem: that could be a kernel driver support issue
[05:22] <holstein> alsa
[05:22] <holstein> who knows
[05:22] <holstein> i would try some live CD's
[05:22] <holstein> theres even a puppy live CD with ubuntustudio pacakges ;)
[05:24] <benhem> hmm, ok
[05:25] <holstein> of course, you should find better alsa/JACK support with that USB device i suggested
[05:25] <benhem> yeah.  I _am_ wondering if I should just go back to karmic for the realtime kernel support
[05:25] <benhem> I hate Unity too :)
[05:26] <holstein> well, dont go for the kernel
[05:26] <holstein> thats over
[05:26] <holstein> seriously
[05:26] <holstein> i mean, im not planning on using unity either
[05:26] <holstein> but, the generic kernel is quite suitable right now
[05:26] <holstein> and will be ready soon
[05:26] <benhem> hmm, ok
[05:26] <holstein> theres the liquorix kernel too
[05:26] <holstein> i mean, try what you want
[05:28] <benhem> well, I appreciate the advice
[05:28] <benhem> I'll also try that #opensourcemusicians
[05:28] <holstein> yeah
[05:28] <holstein> lost of folks there useing ubuntu with the generic kernel doing MIDI
[05:29] <holstein> also, guys use RT kernels of their own with whatever distro's
[05:31] <benhem> I can't imagine there's a downside to trying that lowlatency kernel from the ppa you linked
[05:31] <benhem> if it doesn't replace my generic
[05:32] <holstein> benhem: nothing does anything... you can replace it though
[05:32] <holstein> you just add them
[05:32] <holstein> i go in and tell grub to unhide
[05:32] <holstein> !grub2
[05:32] <holstein> you can read about how to do that there ^^
[05:32] <benhem> huh, ok
[05:32] <holstein> you'll add the PPA, then you'll run sudo apt-get update
[05:33] <holstein> then you can install in... linux-lowlatency or whatever
[05:33] <holstein> sudo apt-get install linux-lowlatency
[05:33] <holstein> then, you can edit /etc/default/grub
[08:54] <kimal73> hello i wont install ubuntu studio, can i do the 11.10 release from dvd?
[09:01] <larstr> 11.10 is indeed available on dvd
[09:21] <kimal73> larstr: yes, but someone had probelms
[09:21] <kimal73> *problems
[09:22] <kimal73> larstr: have you the 11,10?
[09:38] <larstr> kimal73: yes, I'm running 11.10
[09:51] <kimal73> larstr: ok, i have xfce desktop on ubuntu 11.10. So i installed ubuntustudio desktop too. But the kerner realtime isn't on repo of synamtic. Is it the same thing?
[11:01] <SachinDey> I read that UbuntuStudio's new envronment is XFCE, does it has the network manager like gnome that can detect USB modems?
[11:13] <larstr> kimal73: RT kernel is not included anymore
[11:15] <ailo> kimal73, The repo for Ubuntu and Ubuntu Studio is the same. No rt kernel. Future releases should include a -lowlatency kernel however.
[11:16] <ailo> kimal73, The -generic kernel performs fairly well. Depending on your hardware, you might find it good enough for your needs
[11:17] <ailo> Also depending on your needs of course
[11:43] <kimal73> ailo: ok
[12:56] <zx81> hi
[12:56] <zx81> i have sound problem disconnecting after  10 minutes ago ????
[12:58] <zx81> when i use Qjack ctl,  or other app like skype) the sound is crunching and cut
[12:58] <zx81> what is this problem ??
[13:00] <ailo> zx81, Are you using Ubuntu Studio?
[13:01] <zx81> yes
[13:02] <ailo> Do you understand what jack is and that qjackctl is an application for controlling jack?
[13:02] <ailo> I was wondering, since you mentioned Skype and qjackctl as two apps you were having a problem with
[13:02] <zx81> yes i have using jack,
[13:02] <ailo> Do you connect pulseaudio to jack?
[13:03] <ailo> Do you know about pulseaudio?
[13:03] <zx81> skype and jack never connecting with the same config
[13:04] <zx81> but i have the same result
[13:04] <zx81> when i use jack
[13:04] <zx81> or when i use skype with pulse
[13:05] <zx81> i know it is not the same way and config but it look like a memory problem ???
[13:05] <zx81> i search why ??
[13:05] <ailo> I'm still not sure if you are using pulseaudio with jack or not
[13:05] <zx81> no
[13:06] <ailo> Ok, so then it is not a problem with either jack or pulseaudio
[13:06] <zx81> with jack i use alsa
[13:07] <zx81> i have just change of system
[13:07] <zx81> with skype its pulse
[13:08] <ailo> In any case it is not a problem with either jack or pulseaudio
[13:09] <ailo> Have you used the same computer and sound card with Ubuntu Studio in the past?
[13:09] <zx81> waouu sorry i'm just trying to use jack but to day its crach
[13:09] <ailo> Or any other linux installation
[13:09] <zx81> DBUS problem yet
[13:09] <ailo> Do you know hot to set realtime privilige for the user?
[13:10] <ailo> how*
[13:10] <zx81> yes same
[13:10] <zx81> no
[13:10] <zx81> may be its that
[13:10] <ailo> If you always have a sound problem on that computer with linux, I suggest it is a hardware problem
[13:11] <ailo> Pulseaudio does not need realtime privilege, but jack does
[13:11] <zx81> no in the past no problem
[13:11] <ailo> Is it only Skype that does not work, or do you have problems with all applications?
[13:11] <zx81> can u help me to define the privilege??
[13:12] <ailo> To give yourself realtime priority, do this in a terminal: sudo dpkg-reconfigure jackd
[13:13] <ailo> When you are asked if you want to use realtime or not, answer yes
[13:13] <ailo> After that you do this in a terminal: sudo usermod -a -G audio <username>
[13:13] <ailo> replace <username> with your username
[13:13] <zx81> Cannot connect to server socket err = Aucun fichier ou dossier de ce type
[13:13] <ailo> Then reboot
[13:14] <ailo> Just follow those steps, and you will get realtime priority for jack
[13:14] <ailo> Are you comfortable using a terminal?
[13:14] <zx81> all my cumputer is freezing ???
[13:15] <zx81> he windows staty open after clic close
[13:16] <ailo> This information is not bery helpful
[13:16] <ailo> very*
[13:17] <ailo> Pulseaudio should work without problems, except for when you use jack
[13:17] <ailo> jack will only work in realtime mode, if you have set the privileges
[13:18] <ailo> To get realtime privilege, just follow the steps I just described
[13:18] <zx81> when i type sudo dpkg-reconfigure jackd
[13:18] <zx81> its made nothing
[13:19] <ailo> try: sudo dpkg-reconfigure jackd2
[13:20] <ailo> jackd2 should be installed by default, when installing jack. There's also jackd1
[13:20] <ailo> If it's not one, it will be the other
[13:21] <zx81> ok its ok with jackd2
[13:22] <zx81> i must reboot
[13:22] <zx81> ??
[13:22] <zx81> and back after test
[13:22] <zx81> tk
[13:22] <ailo> Yes, you have to reboot
[13:22] <zx81> for help
[13:22] <ailo> np
[13:23] <zx81> at soon for the result
[13:26] <zx81> ailo
[13:26] <zx81> reboot and qjack is open
[13:26] <ailo> zx81, Yes..
[13:27] <ailo> Default settings for qjackctl should work fine
[13:27] <zx81> in connexions i have PulseAudioJanckSink/ Pulse audio Jack Source
[13:27] <zx81> System / System
[13:28] <zx81> i have made a link in / out of sytem to ear my microphone in playback (((((
[13:28] <zx81> all look like fine
[13:29] <ailo> Is this a pure Ubuntu Studio installation, or did you add something to it?
[13:29] <zx81> nothing
[13:29] <ailo> Oneiric?
[13:29] <zx81> yes
[13:29] <ailo> ok
[13:29] <ailo> Sounds like you can have everything running through jack
[13:29] <zx81> there is little change
[13:29] <zx81> its fun
[13:29] <zx81> i must try   skype open
[13:32] <zx81> ok great
[13:32] <zx81> skype is run when i cut jack ___ Normal
[13:33] <zx81> and when i open jack after skype _____   yupppp
[13:33] <zx81> ailo a drink virtual to you !!
[13:34] <ailo> zx81, Have fun!
[13:34] <zx81> what u made with jack ??
[13:34] <zx81> some music ??
[13:35] <ailo> I mostly use a program called puredata
[13:35] <zx81> dont know
[13:35] <ailo> Or rather, pd-extended, which is slightly prettier
[13:35] <ailo> It is a graphical audio/video programming language
[13:36] <zx81> vdjing ?*
[13:37] <ailo> http://puredata.info/
[13:37] <zx81> im french , n u ?
[13:38] <ailo> Swedish/Finnish
[13:38] <zx81> its fun puredata
[13:38] <ailo> I think so
[13:38] <zx81> ok video projection
[13:38] <ailo> Sure, video, but also everything concerning audio
[13:39] <zx81> did u know a ap for lighting dmx
[13:39] <ailo> Nope. I haven't done any light or graphical stuff myself
[13:39] <zx81> ok
[13:40] <zx81> music ?
[13:40] <ailo> Yea, I make music mostly. And you?
[13:40] <zx81> yea
[13:40] <zx81> i use just
[13:40] <zx81> rec
[13:40] <zx81> lol
[13:41] <zx81> since linux
[13:41] <zx81> rec guitar drum bass
[13:41] <zx81> all instrumental
[13:41] <ailo> I started out playing death metal
[13:41] <ailo> Drums and guitar
[13:41] <ailo> I also play piano
[13:41] <ailo> Classical
[13:42] <zx81> did u know a trick to connect more one sound card ??
[13:42] <zx81> me im experimental music
[13:43] <ailo> It is possible to connect more than one sound card, but I believe they have to be the same chip
[13:43] <ailo> At least for pci cards
[13:43] <ailo> I have connected two m-audio cards
[13:43] <zx81> i search but i dont find
[13:43] <ailo> M-66 and LT-1010
[13:43] <zx81> i have maudio producer usb micro
[13:44] <ailo> usb I don't know
[13:44] <zx81> and i search to connect that with a other card
[13:44] <zx81> fine
[13:44] <zx81> great product
[13:45] <zx81> for voice or guitar
[13:45] <ailo> http://alsa.opensrc.org/MultipleUSBAudioDevices
[13:45] <ailo> The problem with usb is that you usually only get 16 bit 44kHz, because there are no dedicated drivers
[13:46] <ailo> Only usb 1.1 compatibility
[13:46] <ailo> Well, maybe 48kHz, 16bits, depending on the setup
[13:47] <ailo> I have almost no experience with usb
[13:47] <ailo> pci works well. I just bought a firewire device last year, and that works good as well
[13:47] <zx81> multiple card its not easy ...
[13:48] <zx81> my english ,,,,
[13:48] <zx81> and all terminal config
[13:48] <zx81> im not expert
[13:48] <ailo> http://alsa.opensrc.org/MultipleCards#Multiple_USB_Audio_Devices
[13:49] <ailo> No, sorry
[13:49] <ailo> This is irrelevant
[13:50] <zx81> ok
[13:51] <zx81> may be  on day i find it
[13:52] <zx81> good day to u
[13:52] <zx81> ???
[13:52] <zx81> soon
[13:52] <zx81> good MeTal stud
[14:53] <zx81> hi !! (Oneiric Ocelot 11.10, cpu 2x 2.7Go, 2x1 Go Ram,  amd64, ATI video card)  problem freezing
[14:56] <zx81> i cant find where its come ?,  much of time its gone when i add more effect or after 10 min using, the sound crunch 1 min, and cut, and after all of windows GUI are break i'm obliged to reboot)
[15:03] <holstein> zx81: if you think its graphics related, try using the vesa driver
[15:03] <holstein> if not... just relax the JACK settings, and try again
[16:00] <zx81> holstein, i have uninstall Flgx
[16:00] <zx81> and its the same problem
[16:01] <zx81> holstein, the sound become clipping
[16:01] <zx81> and stop
[16:02] <ailo> zx81, Is it the same no matter what applications you use?
[16:02] <zx81> i m obliged to reboot
[16:02] <zx81> yes
[16:02] <ailo> Have you tried using a minimal amount of applications running?
[16:02] <zx81> with skype same think, the sound became clipping and stop
[16:03] <ailo> You always have skype on?
[16:03] <zx81> no
[16:03] <zx81> yet i have try no start skype and test with jack
[16:03] <ailo> Does this happen when jack is not active?
[16:03] <zx81> and its the same
[16:04] <zx81> yes
[16:04] <ailo> It doesn't sound like it is a problem with the audio
[16:05] <zx81> ??? manage memory ??
[16:05] <zx81> ??? manage USB
[16:06] <zx81> its since oneiric install
[16:06] <ailo> Could be bad ram memory
[16:07] <zx81> is there a file to fix memory /jack
[16:07] <ailo> You mean set maximum memory for jack?
[16:07] <ailo> You said you get the freeze even when jack is not on
[16:07] <zx81> yes
[16:08] <ailo> So, it would not help
[16:09] <zx81> ??
[16:09] <zx81> TY
[16:10] <zx81> i come to install an old ubuntu studio stable to compare the kernel
[16:10] <ailo> zx81, Settings for jack memory is in /etc/security/limits.d/audio.conf
[16:10] <ailo> You can change the line: @audio   -  memlock    unlimited
[16:11] <ailo> You could change it to: @audio   -  memlock    95
[16:11] <ailo> Or less. Maybe 80
[16:11] <ailo> NO, sorry
[16:11] <ailo> I forgot. It's in actual memory
[16:11] <ailo> Not percentage :P
[16:12] <zx81> so ??
[16:14] <ailo> You set it in MB
[16:14] <ailo> No, wait
[16:14] <ailo> kb
[16:14] <ailo> I have to double-check
[16:16] <zx81> i must go
[16:16] <zx81> ty
[16:16] <zx81> ailo
[16:16] <ailo> Yeah, it's in kb
[16:16] <zx81> ty
