| 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. | 00:45 |
|---|---|---|
| holstein | vir_: ok. is it still installed? what have you done since it was working? and upgrade? | 00:46 |
| holstein | vir_: open a terminal and type "qjackctl" and hit enter.. and see if qjackctl is still installed.. | 00:47 |
| 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 | 00:48 |
| vir_ | Hmm. Was it the upgrade or was it Wine? | 00:49 |
| vir_ | I mean, my question, is, how can one determine what it was? | 00:50 |
| 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 | 00:51 |
| vir_ | What stuff? What shortcuts? | 00:52 |
| TerranceWarrior | wow this sucks | 01:56 |
| 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? | 14:31 |
| cfhowlett | k1mmyyy, there is the #ardour channel as well | 14:34 |
| 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 | 14:35 |
| cfhowlett | k1mmyyy, so no help from me as I use audacity ... | 14:36 |
| k1mmyyy | cfhowlett: no worries, thanks for the tip | 14:36 |
| 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 | 14:40 | |
| 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 | 14:42 |
| 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. | 14:44 |
| OvenWerk1 | Ardour is set up so that you press record first to enable recording then select play to get the transport moving | 14:45 |
| 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? | 14:46 |
| OvenWerk1 | (the ardour UI) | 14:47 |
| k1mmyyy | OvenWerk1: correct | 14:49 |
| OvenWerk1 | hang on... running stuff here. | 14:50 |
| k1mmyyy | no worries | 14:50 |
| 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...\ | 14:51 |
| 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. | 14:52 |
| 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. | 14:53 |
| 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? | 14:54 |
| OvenWerk1 | As on 13.04 pretty good. Our menu drops in on top and give separate sub menus just for audio or whatever. | 14:55 |
| OvenWerk1 | The audio stuff itself, like jackd etc. is UI independant anyway. | 14:56 |
| 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 | 14:57 |
| 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. | 14:58 |
| 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. | 14:59 |
| OvenWerk1 | gnome3 and mir and unity expect a well supported grafics setup and a newer fast machine. | 15:01 |
| OvenWerk1 | The problem seems to be that a lot of the newer faster machines are harder to get lowlatency operation out of. | 15:02 |
| OvenWerk1 | There is a group of system firmware that steals cpu without the OS knowledge. | 15:03 |
| cfhowlett | OvenWerk1, "newer" meaning what? discrete graphics? what? | 15:04 |
| OvenWerk1 | post P4 pretty much. | 15:04 |
| 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. | 15:05 |
| 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 | 15:06 |
| 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. | 15:07 |
| OvenWerk1 | (no hyperthreading) | 15:08 |
| OvenWerk1 | The atom chipsets actually have some of the best lowlatency performance... but poorly supported graphics :P | 15:09 |
| OvenWerk1 | Though I have seen some atom MB with nvidia graphics on them. | 15:10 |
| OvenWerk1 | At the other end the Xeon MB seem to have a bios that will allow switching these things off. | 15:12 |
| OvenWerk1 | cfhowlett: what audio IF are you using? | 15:15 |
| 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 | 15:16 |
| cfhowlett | OvenWerk1, so I noticed. audacity is my friend. | 15:17 |
| OvenWerk1 | 8ms latency is about the best you can get. | 15:17 |
| OvenWerk1 | Sorry 4ms. At least on this one. | 15:19 |
| OvenWerk1 | I can start it at 64 frames if I set periods to 3 | 15:20 |
| OvenWerk1 | k1mmyyy: Sorry we got side tracked... | 15:26 |
| cfhowlett | OvenWerk1, oh, only just ... :) | 15:27 |
| 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 | 15:29 |
| OvenWerk1 | Let us know how it goes. The 13.10 (and 14.04 beta) has ardour 3 in it. | 15:30 |
| 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. | 15:31 |
| OvenWerk1 | I have to do that for each take. :P | 15:33 |
| 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. | 15:34 |
| 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/ | 15:36 |
| cfhowlett | OvenWerk1, thanks! | 15:37 |
| OvenWerk1 | A lot of guys use them on their cameras. | 15:37 |
| 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... | 15:38 |
| 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. | 15:39 |
| cfhowlett | OvenWerk1, yeah, that seems rather - dated. | 15:40 |
| OvenWerk1 | Ya, but still very useful. | 15:43 |
| OvenWerk1 | Works with everything. | 15:43 |
| OvenWerk1 | The one I finally bought http://artproaudio.com/discontinued_products/discontinued_products/product/usbdualtubepre/ | 15:44 |
| 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) | 15:45 |
| OvenWerk1 | They have some new ones out I should look at though | 15:46 |
| OvenWerk1 | Anything new seems to be single channel. | 15:52 |
| OvenWerk1 | hmm, did that mean it worked? | 15:53 |
