[00:45] <vir_> Hello everyone. I am an Ubuntu Studio user. I am having a problem. Yesterday I was using Jack Audio Connection Kit, and today it disappeared. I can no longer select it from the dropdown menu of any program.
[00:46] <holstein> vir_: ok. is it still installed? what have you done since it was working? and upgrade?
[00:47] <holstein> vir_: open a terminal and type "qjackctl" and hit enter.. and see if qjackctl is still installed..
[00:48] <vir_> Ok, it is still installed.
[00:48] <vir_> I did an upgrade and installed Wine as well, since last time.
[00:48] <holstein> vir_: ok.. so, any of that could have broken something
[00:49] <vir_> Hmm. Was it the upgrade or was it Wine?
[00:50] <vir_> I mean, my question, is, how can one determine what it was?
[00:51] <holstein> vir_: it literaly could have been anything, friend
[00:51] <vir_> Is there a way to go back to a previous Ubuntu state?
[00:51] <holstein> vir_: confirm that your stuff is not there.. and make sure that you are just missing the shortcuts
[00:51] <holstein> vir_: play around with things in live CD's
[00:52] <vir_> What stuff? What shortcuts?
[01:56] <TerranceWarrior> wow this sucks
[14:31] <k1mmyyy> hi all!
[14:31] <k1mmyyy> i'm having some trouble with ardour. it's freezing when i click record. i have jack running, i'm in the audio group, and have RT enabled...could anyone help me figure out what's going wrong?
[14:34] <cfhowlett> k1mmyyy, there is the #ardour channel as well
[14:35] <k1mmyyy> cfhowlett: haha thanks again. i am there as well
[14:35] <cfhowlett> k1mmyyy, 2 steps ahead of me ...
[14:35] <k1mmyyy> cfhowlett: figured i'd just hedge my bets, since i'm getting so few responses for this question
[14:35] <k1mmyyy> the only error if i start ardour in the command line is "no space in Ardour-UI request buffer for thread unknown" repeated ad infinitum
[14:36] <cfhowlett> k1mmyyy, so no help from me as I use audacity ...
[14:36] <k1mmyyy> cfhowlett: no worries, thanks for the tip
[14:40] <OvenWerk1> k1mmyyy: When you start ardour, do you see ardour ports in jack?
[14:40] <OvenWerk1> Which ardour version are you running?
[14:40]  * OvenWerk1 hasn't had time to play with ardour3 yet
[14:42] <OvenWerk1> When you say freezing, does that mean you can no longer get anything in ardour to work? or that the recording doesn't move forward?
[14:42] <k1mmyyy> OvenWerk1: i do
[14:44] <OvenWerk1> If you are using ubuntu with ardour, it will be ardour 2 unless the menu icon says ardour 3
[14:44] <k1mmyyy> OvenWerk1: and i'm running 2.8.14
[14:44] <k1mmyyy> jack version 1.9.10
[14:44] <OvenWerk1> sounds normal.
[14:45] <OvenWerk1> Ardour is set up so that you press record first to enable recording then select play to get the transport moving
[14:46] <k1mmyyy> OvenWerk1: yeah, i press the little red record circle on the track, then the big one on the transport menu, which starts blinking
[14:46] <k1mmyyy> then play to start recording
[14:46] <OvenWerk1> And then the UI will no longer respond?
[14:47] <OvenWerk1> (the ardour UI)
[14:49] <k1mmyyy> OvenWerk1: correct
[14:50] <OvenWerk1> hang on... running stuff here.
[14:50] <k1mmyyy> no worries
[14:51] <k1mmyyy> OvenWerk1: over in the ardour channel they called this version of ardour "ancient"...
[14:51] <OvenWerk1> Ya, but I don't recall there being that kind of bug floating around...\
[14:52] <k1mmyyy> OvenWerk1: i've found one or two other mentions of it from googling
[14:52] <OvenWerk1> this one here is also 2.8.14 and I am able to record.
[14:53] <k1mmyyy> OvenWerk1: yeah, i mean i think they're just kind of saying they don't support 2.8 anymore, so they don't have to deal with the issue officially i guess
[14:53] <OvenWerk1> This machine (not mine, but my wife's) has kde with the ubuntustudio metas on top.
[14:54] <OvenWerk1> :) they also don't like to deal with any version not downloaded from their site.
[14:54] <k1mmyyy> yeahhh
[14:54] <cfhowlett> OvenWerk1, LTS only so I'm still on 12.04.  How well is KDE integrated with the US?
[14:55] <OvenWerk1> As on 13.04 pretty good. Our menu drops in on top and give separate sub menus just for audio or whatever.
[14:56] <OvenWerk1> The audio stuff itself, like jackd etc. is UI independant anyway.
[14:57] <OvenWerk1> cfhowlett: The ui shouldn't matter... As far as UIs with more eye candy go, I find kde works much better than the gnome3 stuff
[14:58] <holstein> it would be like running a KDE app in ubuntustudio
[14:58] <holstein> it'll pull in what it needs, and work
[14:58] <OvenWerk1> gnome3 is picky about hardware.
[14:59] <OvenWerk1> I have found Studio's metas work well (for me) on top of kde, xubuntu (duh) and lubuntu. I can hardly run unity and gnome3 won't even start anymore.
[15:01] <OvenWerk1> gnome3 and mir and unity expect a well supported grafics setup and a newer fast machine.
[15:02] <OvenWerk1> The problem seems to be that a lot of the newer faster machines are harder to get lowlatency operation out of.
[15:03] <OvenWerk1> There is a group of system firmware that steals cpu without the OS knowledge.
[15:04] <cfhowlett> OvenWerk1, "newer" meaning what?  discrete graphics?  what?
[15:04] <OvenWerk1> post P4 pretty much.
[15:05] <OvenWerk1> It depends on what is on the MB though.
[15:05] <OvenWerk1> If the graphics is intecgrated with the cpu then the MB is not lowlatency usable.
[15:06] <OvenWerk1> But all of the newer ones have heat minitoring stuff.
[15:06] <cfhowlett> OvenWerk1, I'm torn.  Still running a dual core dell laptop, 2009.  Seriously lust for the the Dell XPS 3800 but no official linux/ubuntu support.  XPS 13 is nice but I need more than 256 gigs.  Or I can chance a Mac Book
[15:07] <OvenWerk1> some of the newer smart ethernet cards can do stuff the os doesn't know too.
[15:07] <OvenWerk1> The intel 5 series chips are better for lowlatency than the 7 series.
[15:08] <OvenWerk1>  (no hyperthreading)
[15:09] <OvenWerk1> The atom chipsets actually have some of the best lowlatency performance... but poorly supported graphics :P
[15:10] <OvenWerk1> Though I have seen some atom MB with nvidia graphics on them.
[15:12] <OvenWerk1> At the other end the Xeon MB seem to have a bios that will allow switching these things off.
[15:15] <OvenWerk1> cfhowlett: what audio IF are you using?
[15:16] <cfhowlett> OvenWerk1, sadly, I had to sell off my presonus 1box so I've got only the internal card
[15:16] <cfhowlett> OvenWerk1, but, unlike you, I'm not making music, only podcasting.
[15:16] <OvenWerk1> Intel HDA systems will not allow jack to even start with -p64
[15:17] <cfhowlett> OvenWerk1, so I noticed.   audacity is my friend.
[15:17] <OvenWerk1> 8ms latency is about the best you can get.
[15:19] <OvenWerk1> Sorry 4ms. At least on this one.
[15:20] <OvenWerk1> I can start it at 64 frames if I set periods to 3
[15:26] <OvenWerk1> k1mmyyy: Sorry we got side tracked...
[15:27] <cfhowlett> OvenWerk1, oh, only just ... :)
[15:29] <OvenWerk1> cfhowlett: the only thing with audacity is that I wish they would open the audio ports at application startup and leave them open till application exit.
[15:29] <k1mmyyy> OvenWerk1: no worries. to be honest right now i'm checking out a live cd of ubuntu studio, just to see if that works out of the box
[15:30] <OvenWerk1>  Let us know how it goes. The 13.10 (and 14.04 beta) has ardour 3 in it.
[15:31] <OvenWerk1> cfhowlett: I find to use audacity with jack (or even pulse) I have to set pause then record then set up the audio, then hit play to begin recording.
[15:33] <OvenWerk1> I have to do that for each take.  :P
[15:34] <cfhowlett> OvenWerk1, the easiest set up I ever had with audacity was via the presonus IF ... even dual mic'd a few times.  worked great.  Now, of course, I'm shooting for portability.
[15:34] <OvenWerk1> I will use mhwaveedit to record and audacity to edit sometimes.
[15:36] <OvenWerk1> cfhowlett: have you looked at the ART USB Dual Pre Project Series?
[15:36] <cfhowlett> OvenWerk1, nope.  link?
[15:36] <OvenWerk1> http://artproaudio.com/art_products/signal_processing/usb_audio_devices/product/usb_dual_pre_ps/
[15:37] <cfhowlett> OvenWerk1, thanks!
[15:37] <OvenWerk1> A lot of guys use them on their cameras.
[15:38] <cfhowlett> no mention of linux support ...
[15:38] <OvenWerk1> Works out of the box
[15:38] <OvenWerk1> I took my laptop into the music store...
[15:39] <OvenWerk1> I would suggest anyone else do the same. Any good store will let you try it out.
[15:39] <cfhowlett> OvenWerk1, nice!  Now I just have to see if they ship to China ...
[15:39] <OvenWerk1> It is a USB 1.1 compliant device.
[15:40] <cfhowlett> OvenWerk1, yeah, that seems rather - dated.
[15:43] <OvenWerk1> Ya, but still very useful.
[15:43] <OvenWerk1> Works with everything.
[15:44] <OvenWerk1> The one I finally bought http://artproaudio.com/discontinued_products/discontinued_products/product/usbdualtubepre/
[15:45] <OvenWerk1> Is no longer sold. But it needed it's own power.
[15:45] <cfhowlett> OvenWerk1, very nice
[15:45] <OvenWerk1> (the one above runs on usb power)
[15:46] <OvenWerk1> They have some new ones out I should look at though
[15:52] <OvenWerk1> Anything new seems to be single channel.
[15:53] <OvenWerk1> hmm, did that mean it worked?
