[14:13] <larsselavy> Hi, I have a problem with cinelerra, i don't know how to solve it. I've just change my computer, i've installed ubuntu studio with realtime core (i don't know if it's linked to my problem) and now i have a sound latency on cinelerra of almost 1 second... Any idea of the problem?
[14:15] <ScottL> larsselavy, do you still have the -generic kernel installed?  you can try booting into it and seeing if the latency changes
[14:18] <larsselavy> ScottL, I don't know if it's installed, how can I know? My computer is a new one, nothing was installed before i install ubuntu studio
[14:19] <ScottL> larsselavy, when you boot the computer, does it show a menu or take you straight to logging in?
[14:21] <larsselavy> straight to log
[14:21] <larsselavy> ScottL,
[14:21] <larsselavy> so i suppose i don't have a generic kernel
[14:21] <ScottL> are you familiar with the command line (also known as the terminal)?
[14:21] <larsselavy> yeah depend on what
[14:22] <ScottL> larsselavy, just because it goes straight to log in doesn't mean you don't have other kernels, that might just be the way grub is set
[14:22] <larsselavy> i mean depend on which command lines
[14:22] <larsselavy> ok
[14:24] <larsselavy> but i don't know how to reset grub...
[14:24] <larsselavy> ScottL,
[14:25] <ScottL> probably the most straight forward is to search in synaptic, are you familiar with synaptic larsselavy ?
[14:25] <ScottL> i would search for 'linux-image-2'
[14:25] <larsselavy> yeah
[14:26] <larsselavy> ScottL,
[14:26] <ScottL> this should show which kernels are installed already
[14:26] <ScottL> larsselavy, which version of ubuntu studio did you install (e.g. lucid, maverick)?
[14:26] <larsselavy> lucid
[14:26] <ScottL> okay, so lucid comes with a -generic kernel by default
[14:27] <ScottL> i would presume then that you added the -realtime kernel manually
[14:27] <ScottL> so unless you removed the -generic kernel, you should still have it
[14:27] <ScottL> and even if you did add it you can always add the -generic again via synaptic
[14:28] <holstein> hey guys :)
[14:28] <larsselavy> i didn't remove it so i suppose i still have it
[14:28] <holstein> larsselavy: what is the output of
[14:28] <holstein> uname -a
[14:28] <holstein> in a terminal
[14:28] <larsselavy> i didn't exactly add the realtime kernel manually, it asked it at installation
[14:28] <holstein> larsselavy: you can post that here
[14:28] <holstein> its just a line
[14:29] <larsselavy> Linux Lillith 2.6.32-26-generic #48-Ubuntu SMP Wed Nov 24 09:00:03 UTC 2010 i686 GNU/Linux
[14:29] <larsselavy> holstein,
[14:29] <ScottL> ah, larsselavy tha was asking if you wanted -realtime privelages, not install the kernel
[14:29] <ScottL> this is to give better performance
[14:29] <larsselavy> ScottL, ah so i don't have the realtime kernel?
[14:29] <larsselavy> ok
[14:30] <ScottL> no real-time kernel, it even shows you that with your uname -a
[14:30] <ScottL> when you use cinelerra are you also using JACK as the sound server?
[14:30]  * ScottL has never used cinelerra
[14:31] <ScottL> hi holstein :)
[14:31] <larsselavy> no alsa
[14:31] <ScottL> hmmm, not sure why there should be latency then
[14:31] <larsselavy> mmm
[14:31] <larsselavy> shit
[14:31] <ScottL> although you probably are using Pulse Audio on top of alsa (it's installed by default)
[14:31] <holstein> larsselavy: how is hte sound otherwise
[14:31] <holstein> ?
[14:31] <holstein> the*
[14:32] <ScottL> larsselavy, you might also check either cinelerra forums or IRC channels
[14:32] <larsselavy> the sound is ok, just as it should have been holstein
[14:32] <holstein> careful, this channel is logged... canonical will make you put a dollar in the 'curse-word' jar ;)
[14:33] <larsselavy> holstein, ?
[14:33] <holstein> larsselavy: can cinelerra use JACK ?
[14:34] <larsselavy> holstein, no
[14:34] <holstein> interesting
[14:34] <holstein> i cant imagine expecting low-latency audio without using JACK in linux
[14:34] <holstein> as a user or a dev
[14:35] <larsselavy> holstein,  maybe it's a cinelerra problem something in the settings, i don't know
[14:35] <holstein> larsselavy: your up to date right?
[14:35] <holstein> with system updates?
[14:36] <larsselavy> yes
[14:36] <holstein> internal sound card?
[14:36] <larsselavy> i have also an external but i don't use it with cinelerra
[14:36] <holstein> what is the device?
[14:36] <holstein> when you run
[14:36] <holstein> lspci
[14:37] <holstein> you can paste that one line here
[14:37] <holstein> the one line about the sound card
[14:37] <larsselavy> (it's an other problem i have i'll ask another time : jack doesn't recognize my external sound card)
[14:37] <holstein> OR use http://paste.ubuntu.com/
[14:38] <larsselavy> http://paste.ubuntu.com/542279/
[14:39] <larsselavy> holstein,
[14:40] <holstein> im not seeing anything obvious searching around on launchpad
[14:40] <holstein> anyways.. let me make a few suggestions
[14:40] <larsselavy> ok
[14:40] <holstein> and you can plug through them and come back
[14:41] <larsselavy> what? (english is not my mother language i didn't get it)
[14:41] <holstein> i think i would assume this is a cinellera issue
[14:41] <holstein> maybe see if there is a git version
[14:42] <holstein> or some latest version PPA
[14:42] <holstein> an avenue you feel comfortable with that lets you get the most recent verion of cinellera
[14:42] <larsselavy> yeah probably i think i had the same problem when i installed cinelerra the first time, some years ago on my old computer but i can't remeber what i did to solve it
[14:43] <holstein> maybe they have a mailing list if the IRC channel is dead
[14:43] <holstein> after exausting those avenues
[14:43] <larsselavy> they have a mailing list
[14:43] <holstein> you can try updating alsa
[14:43] <holstein> http://ubuntuforums.org/showthread.php?p=6589810#post6589810
[14:43] <holstein> but my money is on cinellera
[14:44] <holstein> larsselavy: about the external device and JACK
[14:44] <holstein> you can search here http://www.alsa-project.org/main/index.php/Matrix:Main
[14:44] <holstein> see if you find the device
[14:44] <holstein> if its there, you should see info about how well alsa supports it
[14:45] <holstein> and what hoops you need to jump through
[14:45] <holstein> one easy-ish way to isolate the USB device is by disabling the internal sound card in the bios
[14:45] <holstein> at least temporarily
[14:46] <holstein> there are a couple commands i would run in the terminal right after plugging the device in
[14:46] <holstein> lsusb
[14:46] <holstein> that should list all the USB devices that the machine can see
[14:47] <holstein> and
[14:47] <holstein> aplay -l
[14:47] <holstein> and
[14:47] <holstein> arecord -l
[14:47] <ScottL> larsselavy, do you have to use cinelerra?  you might also try openshot or blender for video editing
[14:47] <holstein> ^^ those list what deivces can play and record audio, and how many inputs you have
[14:48] <holstein> ScottL: how is openshot?
[14:48] <holstein> what did you use to do those vids you did?
[14:50] <ScottL> holstein, i used blender actually :)
[14:51] <ScottL> but openshot is pretty stable from what i read, full of features, and pretty simple
[14:51] <holstein> im going to try http://jaycut.com/
[14:52] <ScottL> isn't that the online video editing service?
[14:52] <holstein> yeah
[14:52] <holstein> i made an account
[14:53] <ScottL> well, it should be OS agnostic and stable :)
[15:28] <ScottL> http://ardour.org/taxonomy/term/23/0
[15:28] <ScottL> paul has been making lots of posts showcasing new features and changes in ardour 3.0
[15:28] <ScottL> he's probably made close to thirty in the last three or four days
[17:35] <holstein> ScottL: thats a good sign :)
[17:36] <gnusar> has anyone of you suceeded to install ustudio as a virtual machine via virtual box? i am struggling with getting the audio line in to work.. is probably more a virtual box related issue but i thought it does not hurt to ask here
[17:36] <holstein> yeah, this is a good place to ask gnusar
[17:37] <holstein> i dont think your going to get the performance you need in VM
[17:37] <holstein> gnusar: what is the goal?
[17:37] <holstein> are you running windows or OSX host?
[17:37] <gnusar> holstein: i am running win7 and want to record some guitar tunes
[17:37] <holstein> i think you'd do betting with a wubi install
[17:38] <holstein> and that is just as removable
[17:38] <holstein> in theory
[17:38] <holstein> i had good luck with a wubi install in XP
[17:38] <holstein> when i was transitioning the studio to linux
[17:39] <gnusar> sounds good.. so you were also interested in sound recording and processing?
[17:39] <holstein> yup
[17:39] <gnusar> thank you holstein
[17:40]  * holstein doesnt do a lot of MIDI
[17:40] <holstein> or video
[17:40] <holstein> gnusar: check out #opensourcemusicians
[17:42] <gnusar> holstein: live shows! sounds interesting
