[01:31] <georgeowell> Just installing 15.10 on my laptop
[01:32] <georgeowell> Want to dual boot with the Windows malware
[01:32] <georgeowell> So tense...
[01:39] <georgeowell> hehe worked like a charm
[02:44] <georgeowell> Will the GNOME3 desktop work on top of all the ubuntu studio stuff
[02:53] <OvenWerks> 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] <georgeowell> Maybe I'll leave that experiment for another time.
[02:57] <georgeowell> Somethings happened with my Jack setup already
[02:58] <georgeowell> I'm getting D-BUS: Jack Server could not be started
[02:58] <OvenWerks> 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] <georgeowell> is there a way of returning to the default config?
[02:58] <OvenWerks> how do you start jack? qjackctl?
[02:59] <georgeowell> yep
[02:59] <georgeowell> The only parameter I changed was Frames/Period
[02:59] <OvenWerks> in a terminal try killall -9 jackd jackdbus.
[02:59] <OvenWerks> default is 1024/2
[03:00] <OvenWerks> then restart jackdbus using qjackctl
[03:00] <georgeowell> OvenWerks, I got "no process found"
[03:00] <OvenWerks>  sometimes if jack is not running a jack application will start jackd which blocks jackdbus from starting
[03:01] <OvenWerks> that is ok I think.
[03:01] <OvenWerks> what happens if you try jack_control start?
[03:03] <leo_> hey sorry just jumped into IRC on Ubuntu Studio box
[03:03] <OvenWerks> hello
[03:04] <leo_> OvenWerks, I'm getting:
[03:04] <leo_> DBus exception: org.jackaudio.Error.Generic: Failed to open server
[03:04] <leo_> I rebooted as well
[03:04] <OvenWerks> Does this mean you are the same person as georgeowell ?
[03:04] <leo_> yep
[03:04] <OvenWerks> ah.
[03:05] <leo_> sorry, asif I needed the make the situation any more complicated :)
[03:05] <OvenWerks> But it was working before?
[03:06] <OvenWerks> leo_: try this in a terminal:
[03:06] <OvenWerks> cd /tmp && wget http://jackaudio.org/downloads/adevices.sh && bash ./adevices.sh
[03:06] <leo_> yep perfectly
[03:06] <OvenWerks> paste the output to pastebin.com or similar
[03:08] <leo_> Would it help if I showed you the errors direct from qjackctl messages?
[03:08] <OvenWerks> The above command will tell more I think.
[03:09] <leo_> there's the qjackctl stuff
[03:09] <leo_> http://pastebin.com/Xj7nPhQE
[03:10] <leo_> and the result of the jackaudio script
[03:10] <leo_> http://pastebin.com/Dzm2JFsT
[03:10] <OvenWerks> leo_: That just says something else is using it.
[03:11] <leo_> So something is starting jack automatically?
[03:12] <OvenWerks> leo_: or that you have specified a device that does not exist.
[03:12] <leo_> OvenWerks, thanks so much for this btw. I only just installed so this is super frustrating.
[03:12] <OvenWerks> The second one shows nothing is using a device
[03:12] <OvenWerks> which device are you trying to connect to?
[03:13] <leo_> ok wtf, it just started working again. Sorry 2 secs, let me just test.
[03:13] <OvenWerks> The second paste should have had a lot more info.
[03:15]  * OvenWerks has not run that with no jackdbus running though
[03:16] <OvenWerks> leo_: I think hw:MID is the device you want to use.
[03:17] <leo_> Yep, that's the right device.
[03:17] <leo_> I just don't understand why it got all messed up
[03:18] <leo_> I thought it was working for a second but now I'm in the same situation as when I began
[03:21] <OvenWerks> ok lets try jack_control exit
[03:22] <leo_> tried that already
[03:22] <OvenWerks> jack_control ds alsa dps capture none dps playback none
[03:22] <leo_> This is what I get on jack_control start: DBus exception: org.jackaudio.Error.Generic: Failed to open server
[03:23] <OvenWerks> jack_control jack_control dps device hw:MID dps rate 48000 dps period 1024 dps nperiods 2 start
[03:23] <OvenWerks> ok killall -9 jackdbus jackd
[03:23] <leo_> same error
[03:23] <OvenWerks> then three commands above in the same order.
[03:25] <leo_> ok, it appears to be working
[03:25] <leo_> shall I try qjackctl
[03:25] <leo_> ?
[03:26] <OvenWerks> qjackctl should show jack as already running
[03:26] <OvenWerks> (go ahead)
[03:26] <leo_> hehe
[03:26] <leo_> its working
[03:26] <leo_> thanks so much!! :)
[03:27]  * leo_ hugs OvenWerks in glee
[03:27] <OvenWerks> leo_: ok, that tells me that you probably have an odd setup in qjackctl.
[03:27] <leo_> ok
[03:28] <leo_> it's something to do with "frames/period"
[03:28] <leo_> it is now 4096
[03:28] <OvenWerks> leo_: did you change name from (default)?
[03:28] <leo_> nope
[03:28] <OvenWerks> 4096 may be to high for your card
[03:29] <OvenWerks> it is too high for my multi track card.
[03:29] <leo_> I changed it from 4096 and then the problem started
[03:29] <OvenWerks> try 1024 (which is what we used from command line)
[03:29] <leo_> It works on 4096
[03:30] <leo_> is that the buffer size?
[03:30] <OvenWerks> It work on 1024, because that is how we started it from the command line
[03:30] <leo_> ok
[03:30] <leo_> I'll change it in qjack and see what happens
[03:30] <OvenWerks> it is part of the buffer size.
[03:31] <OvenWerks> buffer size is frames times periods
[03:32] <OvenWerks> 1024/2 is normally the highest anyone goes
[03:32] <leo_> yep
[03:32] <leo_> It's working
[03:32] <OvenWerks> there will be a noticable delay between audio going in to audio coming out
[03:32] <leo_> yep
[03:32] <OvenWerks>  (43 ms)
[03:33] <leo_> Is it possible to go lower with intel audio without xruns?
[03:33] <OvenWerks> 64/2 is very good, but I find internal audio can normally not get below 128/2
[03:33] <leo_> I still need to get a linux compatible interface
[03:33] <OvenWerks> no xruns depends on a lot of things :)
[03:33] <leo_> i'll try 256
[03:34] <leo_> hehe my bastion of fire into the linux audio world!!
[03:34] <OvenWerks> On my lap top I found I had to unload the wifi driver.
[03:34] <leo_> ah yes, even disabling the wifi on my mac helps latency
[03:35] <leo_> 256 is fine for me right now
[03:36] <OvenWerks> 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] <leo_> I'm going to get one of those focusrite scarlett interfaces
[03:36] <leo_> then see how far I can push it
[03:36] <OvenWerks> with USB try each USB plug on the computer. Some of them with share interupts with other things.
[03:37] <OvenWerks> you want a clean interupt for lowest latency
[03:37] <leo_> I'm not actually using this linux setup for recording yet, just for playing around with all the cool free software stuff
[03:37] <leo_> I'm on a thinkpad so there's many to try
[03:37] <leo_> What audio interface are you using?
[03:38] <OvenWerks> I am using an old Maudio delta66 PCI card.
[03:38] <OvenWerks> I can get .7ms latency with it. (16/2)
[03:39] <OvenWerks> (plus 1ms each way for the ADC/DAC)
[03:39] <leo_> that's pretty amazing
[03:39] <leo_> on my macbook pro, I probably get 11ms.
[03:39] <OvenWerks> nobody makes PCI stuff anymore
[03:40] <OvenWerks> PCIe stuff is $1k for just about anything worth whle.
[03:40] <leo_> From research, some of the Focusrite USB interfaces are working well with Linux
[03:41] <OvenWerks> yes or the 1818vsl (i think)
[03:42] <OvenWerks> https://www.presonus.com/products/AudioBox-1818VSL or it's siblings
[03:43] <OvenWerks> (theres a 22 and a 44 as well)
[03:44] <OvenWerks> 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] <OvenWerks> otherwise you have to use sample rate conversion to sync them.
[03:45] <leo_> thanks for the advice
[03:46] <leo_> I was looking at this: http://us.focusrite.com/usb-audio-interfaces/scarlett-6i6
[03:46] <leo_> I've used them before
[03:47] <leo_> and can test with Linux before I buy
[03:48] <OvenWerks> 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] <OvenWerks> 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] <leo_> Yeh, a good music shop will be cool with that.
[03:49] <leo_> Yeh, only need the raw ins and outs
[03:49] <leo_> not bothered about their fancy routing software
[03:50] <OvenWerks> heres the user guide: http://d3se566zfvnmhf.cloudfront.net/sites/default/files/focusrite/downloads/9439/scarlett6i6-user-guideen.pdf
[03:51] <leo_> Thanks
[03:52] <leo_> You've been so helpful. What a credit to this community.
[03:52] <OvenWerks>  not sure if MixControl would be useful from wine or not... or if you want wine on the system
[03:52] <leo_> I'll send you over some of the music I make using free software :)
[03:52] <leo_> I just got back from Berlin, so it's all Techno I'm afraid.
[03:57] <leo_> Well anyway all credit to the Ubuntu Studio project
[03:58] <leo_> didn't think I'd be having this much fun with music on Linux
[03:58] <OvenWerks> Almost all manufactures have the manuals on line.
[03:59] <OvenWerks> It seems that 6i6 stuff in Linux is quite new 15.04 and newer
[04:01] <leo_> ah maybe I might need to go for a more basic model
[04:01] <leo_> that has more stable support
[04:02] <leo_> I wonder who is working on that specifically
[04:02] <leo_> I'll love to donate a bit of cash to them
[04:02] <OvenWerks> I think it will be similar for any of them.
[04:02] <OvenWerks> The alsa project is doing that.
[04:04] <leo_> It's great work
[04:05] <leo_> Ardour is looking super nice these days as well
[04:07] <OvenWerks> anyway, I should go eat.
[04:10] <leo_> Thanks so much for your help!
[04:11] <leo_> I copied all the commands so I should be able to fix it myself next time
[04:15] <leo_> here's a sample of what I'm working on
[04:16] <leo_> http://46.101.47.165/owncloud/index.php/s/cQ2Wxr6seapw4vH
[04:16] <leo_> for anyone who's interested :)
