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