[01:31] Just installing 15.10 on my laptop [01:32] Want to dual boot with the Windows malware [01:32] So tense... [01:39] hehe worked like a charm [02:44] Will the GNOME3 desktop work on top of all the ubuntu studio stuff [02:53] georgeowell: no reason that I know for it not to so long as you are using ubuntu packages. Can't say as I have been there myself though. [02:56] Maybe I'll leave that experiment for another time. [02:57] Somethings happened with my Jack setup already [02:58] I'm getting D-BUS: Jack Server could not be started [02:58] I think we need a better jack tool... I would like a better jack package as well. having both jackd and jackdbus on the same system does have some uses, but seems to cause more trouble than it is worth. [02:58] is there a way of returning to the default config? [02:58] how do you start jack? qjackctl? [02:59] yep [02:59] The only parameter I changed was Frames/Period [02:59] in a terminal try killall -9 jackd jackdbus. [02:59] default is 1024/2 [03:00] then restart jackdbus using qjackctl [03:00] OvenWerks, I got "no process found" [03:00] sometimes if jack is not running a jack application will start jackd which blocks jackdbus from starting [03:01] that is ok I think. [03:01] what happens if you try jack_control start? [03:03] hey sorry just jumped into IRC on Ubuntu Studio box [03:03] hello [03:04] OvenWerks, I'm getting: [03:04] DBus exception: org.jackaudio.Error.Generic: Failed to open server [03:04] I rebooted as well [03:04] Does this mean you are the same person as georgeowell ? [03:04] yep [03:04] ah. [03:05] sorry, asif I needed the make the situation any more complicated :) [03:05] But it was working before? [03:06] leo_: try this in a terminal: [03:06] cd /tmp && wget http://jackaudio.org/downloads/adevices.sh && bash ./adevices.sh [03:06] yep perfectly [03:06] paste the output to pastebin.com or similar [03:08] Would it help if I showed you the errors direct from qjackctl messages? [03:08] The above command will tell more I think. [03:09] there's the qjackctl stuff [03:09] http://pastebin.com/Xj7nPhQE [03:10] and the result of the jackaudio script [03:10] http://pastebin.com/Dzm2JFsT [03:10] leo_: That just says something else is using it. [03:11] So something is starting jack automatically? [03:12] leo_: or that you have specified a device that does not exist. [03:12] OvenWerks, thanks so much for this btw. I only just installed so this is super frustrating. [03:12] The second one shows nothing is using a device [03:12] which device are you trying to connect to? [03:13] ok wtf, it just started working again. Sorry 2 secs, let me just test. [03:13] The second paste should have had a lot more info. [03:15] * OvenWerks has not run that with no jackdbus running though [03:16] leo_: I think hw:MID is the device you want to use. [03:17] Yep, that's the right device. [03:17] I just don't understand why it got all messed up [03:18] I thought it was working for a second but now I'm in the same situation as when I began [03:21] ok lets try jack_control exit [03:22] tried that already [03:22] jack_control ds alsa dps capture none dps playback none [03:22] This is what I get on jack_control start: DBus exception: org.jackaudio.Error.Generic: Failed to open server [03:23] jack_control jack_control dps device hw:MID dps rate 48000 dps period 1024 dps nperiods 2 start [03:23] ok killall -9 jackdbus jackd [03:23] same error [03:23] then three commands above in the same order. [03:25] ok, it appears to be working [03:25] shall I try qjackctl [03:25] ? [03:26] qjackctl should show jack as already running [03:26] (go ahead) [03:26] hehe [03:26] its working [03:26] thanks so much!! :) [03:27] * leo_ hugs OvenWerks in glee [03:27] leo_: ok, that tells me that you probably have an odd setup in qjackctl. [03:27] ok [03:28] it's something to do with "frames/period" [03:28] it is now 4096 [03:28] leo_: did you change name from (default)? [03:28] nope [03:28] 4096 may be to high for your card [03:29] it is too high for my multi track card. [03:29] I changed it from 4096 and then the problem started [03:29] try 1024 (which is what we used from command line) [03:29] It works on 4096 [03:30] is that the buffer size? [03:30] It work on 1024, because that is how we started it from the command line [03:30] ok [03:30] I'll change it in qjack and see what happens [03:30] it is part of the buffer size. [03:31] buffer size is frames times periods [03:32] 1024/2 is normally the highest anyone goes [03:32] yep [03:32] It's working [03:32] there will be a noticable delay between audio going in to audio coming out [03:32] yep [03:32] (43 ms) [03:33] Is it possible to go lower with intel audio without xruns? [03:33] 64/2 is very good, but I find internal audio can normally not get below 128/2 [03:33] I still need to get a linux compatible interface [03:33] no xruns depends on a lot of things :) [03:33] i'll try 256 [03:34] hehe my bastion of fire into the linux audio world!! [03:34] On my lap top I found I had to unload the wifi driver. [03:34] ah yes, even disabling the wifi on my mac helps latency [03:35] 256 is fine for me right now [03:36] 256/2 is not too bad, 512 sounds echoy if you are monitoring from the soundcard. Recording with 1024/2 with external monitoring is fine though. [03:36] I'm going to get one of those focusrite scarlett interfaces [03:36] then see how far I can push it [03:36] with USB try each USB plug on the computer. Some of them with share interupts with other things. [03:37] you want a clean interupt for lowest latency [03:37] I'm not actually using this linux setup for recording yet, just for playing around with all the cool free software stuff [03:37] I'm on a thinkpad so there's many to try [03:37] What audio interface are you using? [03:38] I am using an old Maudio delta66 PCI card. [03:38] I can get .7ms latency with it. (16/2) [03:39] (plus 1ms each way for the ADC/DAC) [03:39] that's pretty amazing [03:39] on my macbook pro, I probably get 11ms. [03:39] nobody makes PCI stuff anymore [03:40] PCIe stuff is $1k for just about anything worth whle. [03:40] From research, some of the Focusrite USB interfaces are working well with Linux [03:41] yes or the 1818vsl (i think) [03:42] https://www.presonus.com/products/AudioBox-1818VSL or it's siblings [03:43] (theres a 22 and a 44 as well) [03:44] I would stay away from the USB mic. You want your interface to have both the inputs and outputs you use for recording if possible. [03:44] otherwise you have to use sample rate conversion to sync them. [03:45] thanks for the advice [03:46] I was looking at this: http://us.focusrite.com/usb-audio-interfaces/scarlett-6i6 [03:46] I've used them before [03:47] and can test with Linux before I buy [03:48] looks good but I have never used one before. I normally take my laptop to the music store and try what I want in the store. [03:48] be aware that it may not be possible to control everything in the box, so if any effects come with it you may not be able to control them. [03:49] Yeh, a good music shop will be cool with that. [03:49] Yeh, only need the raw ins and outs [03:49] not bothered about their fancy routing software [03:50] heres the user guide: http://d3se566zfvnmhf.cloudfront.net/sites/default/files/focusrite/downloads/9439/scarlett6i6-user-guideen.pdf [03:51] Thanks [03:52] You've been so helpful. What a credit to this community. [03:52] not sure if MixControl would be useful from wine or not... or if you want wine on the system [03:52] I'll send you over some of the music I make using free software :) [03:52] I just got back from Berlin, so it's all Techno I'm afraid. [03:57] Well anyway all credit to the Ubuntu Studio project [03:58] didn't think I'd be having this much fun with music on Linux [03:58] Almost all manufactures have the manuals on line. [03:59] It seems that 6i6 stuff in Linux is quite new 15.04 and newer [04:01] ah maybe I might need to go for a more basic model [04:01] that has more stable support [04:02] I wonder who is working on that specifically [04:02] I'll love to donate a bit of cash to them [04:02] I think it will be similar for any of them. [04:02] The alsa project is doing that. [04:04] It's great work [04:05] Ardour is looking super nice these days as well [04:07] anyway, I should go eat. [04:10] Thanks so much for your help! [04:11] I copied all the commands so I should be able to fix it myself next time [04:15] here's a sample of what I'm working on [04:16] http://46.101.47.165/owncloud/index.php/s/cQ2Wxr6seapw4vH [04:16] for anyone who's interested :)
