[03:15] <holstein> tech1: you can do "full music production" with latency
[03:15] <holstein> it depends on what *type* of music production you are doing as to what latency you might require
[03:16] <holstein> if you are not doing live playing of software synths or live effects processing, then who cares if it takes 80ms for the sound to get from the computer to the speakers when you want to hear it
[03:17] <holstein> soemthing rendered will sound the same rendered at high or low latency...
[11:20] <megatlantis> hi
[11:21] <megatlantis> i have some problem while installing ubuntu studio , can i get some help please ?
[11:43] <megatlantis> :'(
[12:24] <megatlantis> ...
[16:18] <Jim|> hi guys, installed ubuntu studio (my first linux, so please excuse my lack of knowledge). Im having trouble getting my second monitor running. (Nvidia gtx560 gfx card). Im trying to set it up via "Nvidia X Server Settings". I cannot enable the second monitor. It is recognized, but wont activate. Does somebody have an advise?
[16:24] <tech1> is the apply button greyed out? i had that problem too
[16:26] <Jim|> nope, apply is functional - but gives me the following error: "The current settings cannot be competly applied due to one or more of the following reasons: "The location of an X screen has changed, The location type of an X screen has changed, The color depth ...().,.., An X screen has been added or removed, Xinamera is being enabled/disabled...
[16:26] <Jim|> telling me to save the config to the xconfig file and restart the X server
[16:26] <Jim|> i hit the button "save to X config file", authorised with my credential, but still nothing happens
[16:27] <tech1> i also had that... try saving the config file
[16:27] <tech1> try rebooting
[16:27] <Jim|> ok
[16:27] <Jim|> brb :)
[16:27] <Jim|> thx so far
[16:30] <jim__> hiho
[16:30] <jim__> tech1, thanks that worked
[16:30] <jim__> i tryied the reboot before, but probably screwed up somewhere ':)
[16:30] <jim__> can i ask another probably more question ? :)
[16:31] <jim__> im using m-audio delta 1010lt soundcard and have NO IDEA how to get my sound working
[16:31] <jim__> i read about something like "jack servers"
[16:31] <jim__> any advise on material that can help me understand how linux audio should work ? Or some experience with said soundcard?
[16:32] <ailo> jim__: It should work just fine
[16:32] <ailo> jim__: What's your problem with it?
[16:32] <ailo> I have both the 1010LT and the 66
[16:32] <jim__> i dont get soundplayback when i f.e. hit an mp3
[16:32] <ailo> jim__: You have an internal card as well, right?
[16:32] <jim__> yep
[16:33] <ailo> jim__: You need to set the m-audio card as default in pulseaudio settings
[16:33] <ailo> The volume applet -> "settings/mixer something"
[16:33] <jim__> !!!! sounds good, ill try it now
[16:36] <jim__> i think im a bit lost here
[16:36] <jim__> went to /audip production/mixers/pulse audio
[16:36] <jim__> shows 2 output devices
[16:37] <jim__> 1) GF110 High definition audio controller digital stereo (HDMI) <- dont want that eh ? :)
[16:37] <ailo> jim__: That's the audio out from your hdmi
[16:37] <jim__> and 2) ICE1712 ENVY24 PCI Multio channel i/O controller analog stereo
[16:37] <jim__> thats the delta
[16:37] <ailo> jim__: Yeah
[16:37] <ailo> There's a button. Set as fallback
[16:37] <ailo> Use that
[16:38] <jim__> which one as fallback?
[16:38] <jim__> the HDMI or envy?
[16:38] <ailo> The one you want to use
[16:38] <jim__> ok
[16:40] <ailo> jim__: Working?
[16:40] <jim__> sadly not
[16:40] <jim__> audacious playing an mp3 atm,
[16:40] <ailo> jim__: There's another thing you need to do
[16:40] <ailo> jim__: Just remembered.
[16:40] <jim__> chose "pulseaudio" in audacious
[16:40] <ailo> jim__: The levels are all at 0. Use the mudita24 mixer
[16:41] <jim__> oh man thanks so much for this help
[16:41] <jim__> ok
[16:41] <ailo> jim__: You need to set dac levels
[16:41] <ailo> dac = digital to audio
[16:42] <ailo> mudita24 is a mixer for devices that have the envy24 chip, so not only m-audio devices
[16:42] <jim__> ok, understood!
[16:42] <jim__> fiddling with it now
[16:43] <ailo> jim__: I'd point you to a doc page about this, but it seems a lot of the ubuntu sites are down at the moment, including ubuntustudio.org
[16:43] <jim__> cool in mudita i get a graphical signal now
[16:44] <jim__> booooooooooooyah
[16:44] <jim__> I got sound :)
[16:44] <ailo> jim__: What are your plans with ubuntustudio? What are you going to use it for?
[16:44] <jim__> actually, im just using it to gain more linux experience. :)
[16:45] <jim__> i cannot produce here i guess, as im using ableton
[16:45] <ailo> Not with ableton, I don't think (never tried it).
[16:46] <ailo> There are other applicatiions though
[16:46] <jim__> ive just created a nice triple boot system (xp,7,ubuntustudio). I am using lots of linux for work (only terminal).
[16:46] <jim__> yeah i saw that the trackerstuff was ported successfully to linux
[16:46] <jim__> might be worth a try
[16:46] <jim__> :)
[16:46] <ailo> There are some linux only software too
[16:46] <jim__> any good daws?
[16:47] <ailo> Depends on what you want to use them for. Ardour is a great recording/mixing system
[16:47] <ailo> Qtractor is a nice all in one
[16:47] <ailo> There's also rosegarden, and a couple more
[16:47] <jim__> i found the aspect of an realtime kernel really fascinating and imho linux should be superior to any win system in terms of latency and processing
[16:48] <ailo> Yep
[16:48] <jim__> ill write that down and check those out
[16:48] <ailo> linux-lowlatency is essentially that
[16:48] <ailo> But, not actually a hard realtime kernel
[16:48] <ailo> The main linux source is including more and more of the realtime patch
[16:49] <ailo> So, with a proper configuration, you can turn linux-generic into a suitable kernel for low latency operation
[16:49] <ailo> And that's what linux-lowlatency is
[16:49] <ailo> A couple of configs make all the difference
[16:49] <jim__> so if i understand correctly, the simple install of ubuntu studio doesnt include the realtime/low latency kernel yet ?
[16:50] <ailo> It includes linux-lowlatency
[16:50] <ailo> I personally don't see any need for -realtime
[16:50] <jim__> ah and theres a diff to rt kernel
[16:50] <jim__> ok
[16:50] <ailo> The rt kernel is the one that diffs
[16:50] <jim__> i feel like a noob with linux now :)
[16:50] <ailo> The rt kernel is experimental. The patch for it doesn't come out for all versions.
[16:51] <ailo> Some prefer it, but Ubuntu Studio decided, after some testing, that the -lowlatency was more than good enough
[16:52] <jim__> yeah,  as far as i read on wiki, realtime comes at a cost of "delaying" other things
[16:52] <ailo> That aspect I don't think is different on -lowlatency
[16:53] <ailo> I mean, compared to -rt
[16:53] <ailo> The delay is quite small
[16:53] <ailo> Don't know how small, but not so you notice it as a desktop user.
[16:54] <jim__> yeah i think so :)
[16:54] <ailo> What you do notice is that even when the system is using max cpu for non realtime operation, the realtime operation is not affected
[16:54] <jim__> if one really needs realtime, its "back to dos" :)))
[16:55] <ailo> At least when you have big enough latency. At really low latencies, some things will affect performance
[16:55] <jim__> btw, is there any need for me to use "Jack" in any way? The only thing i need my linux being capable of is playing some sounds/mp3 and maybe some of the daws you mentioned previously
[16:56] <ailo> jim__: Some DAWs will need jack. You can control it with qjackctl
[16:56] <jim__> as far as i understood now, im able to use mudita for everything
[16:56] <jim__> ah ic
[16:57] <ailo> jim__: mudita is just for adjusting the HW levels inside your envy24 device
[16:57] <jim__> ahhhhh mixer only
[16:57] <jim__> !
[16:57] <jim__> thats a totally different topology
[16:57] <ailo> jim__: All you need to do with qjackctl is choose the right device and start it
[16:57] <jim__> i need to relearn :)
[16:57] <ailo> jim__: Usually, you start jack first, and then the application that depends on it
[16:58] <ailo> qtractor will need jack
[16:58] <ailo> Ardour can operate without it, but is designed to work with jack (same person behind it)
[16:59] <ailo> jim__: On Ubuntu Studio, the desktop sound is managed by "pulseaudio". "jack" is a different sound system, but both use "alsa" drivers to operate audio devices
[17:00] <ailo> jim__: With default settings, when you start qjackctl, "pulseaudio" will create sinks for "jack", so you can connect "pulseaudio" outputs and inputs to "jack".
[17:00] <ailo> jim__: You'll need to set PA(pulseaudio), to use jack manually though
[17:00] <jim__> omg thats so helpful
[17:00] <ailo> jim__: The second thing you'd want to learn about qjackctl is connections.
[17:01] <ailo> jim__: You can connect any jack application to any other jack application
[17:01] <ailo> jim__: The audio device is a connection point, just like applications
[17:01] <ailo> jim__: Usually things autoconnect, but you usually want to do your own connections
[17:02] <ailo> jim__: Anyway, you'll figure it out.
[17:02] <jim__> man you just saved me HOURS of reading
[17:02] <jim__> and explained it very good!
[17:02] <jim__> i just got my first jack server started
[17:02] <jim__> :)
[17:03] <ailo> Thanks. Yeah, it does take some time getting into at first
[17:03] <ailo> I remember not getting sound from my Delta device
[17:03] <ailo> took me a while to figure that one out
[17:03] <ailo> Almost 10 years ago by now
[17:03] <jim__> hehe
[17:04] <jim__> and your running linux only ?
[17:04] <ailo> Yeah, I dumped Windows for good a few years ago
[17:04] <jim__> well if your into recording and mixing, no problem. :_) but the big DAWs leave you hanging without any linux support
[17:04] <jim__> its a pity!
[17:06] <jim__> honestly, i just switched from my external firewire m-audio audiophile interface to the delta 1010lt to be able to run linux... i was so pissed, m-audio never released specs to linux developers
[17:06] <jim__> and then i read that emu and esi are giving lots of trouble for windows (allthough they use envy also).
[17:06] <jim__> BSOD if two apps access asio on XP.... OMG wtf :)
[17:06] <jim__> so i had to get an maudio again.... damn :)
[17:06] <ailo> You can look at it this way too. If you use a big commercial DAW, chances are your music making will be greatly influenced by the tools they make for you
[17:07] <jim__> 100% correct observation
[17:07] <ailo> I own a focusrite pro 40. Works well with linux
[17:08] <ailo> There are a few firewire devices that work
[17:08] <ailo> Only one 8ch usb device with full support, AFAIK
[17:08] <jim__> heh, yeah thats expansive stuff :)
[17:08] <ailo> Maybe two, but one of them won't give you the best performance
[17:09] <jim__> i was surprised, that i didnt have to fiddle with drivers and the delta JUST WORKED (after you helped) :)
[17:09] <ailo> drivers are all baked in into the kernel
[17:09] <ailo> So, if it works, it usually just works
[17:09] <ailo> No after install maintenance :)
[17:10] <ailo> proprietary graphic drivers are an exception of course
[17:10] <ailo> But, Ubuntu has managed to make that pretty easy too
[17:10] <jim__> hehe yeah surprisingly :)
[17:11] <jim__> for work i just use terminal linux redhead stuff, so its my first real Linux with "gui" :)
[17:11] <ailo> You mean, Red Hat?
[17:11] <jim__> actually that gui (X-desktop whatever u call it) confused the hell out of me
[17:11] <jim__> yea
[17:11] <ailo> XFCE
[17:11] <jim__> :))))))) haha <--- back to noob :)
[17:11] <jim__> oh btw
[17:12] <jim__> i got another question
[17:12] <jim__> maybe u know how to advise
[17:12] <jim__> i wanna config my grub bootloader
[17:12] <jim__> change the order of entrys
[17:12] <jim__> and hide the memory tests
[17:12] <jim__> is there an easy way? :)
[17:13] <jim__> i read this article: http://tombuntu.com/index.php/2011/09/25/how-to-change-boot-order-in-ubuntu-11-04/
[17:13] <ailo> jim__: /etc/default/grub
[17:14] <ailo> jim__: I think there are some graphic tools too
[17:14] <jim__> but in etc/default/grub, there a no settings whatsoever concerning the entryies
[17:14] <ailo> jim__: GRUB_DEFAULT=0
[17:14] <jim__> in boot/grub/grub.cfg i found much more
[17:16] <jim__> hm?
[17:16] <jim__> grub_default equals 0
[17:16] <jim__> :)
[17:16] <jim__> yeah
[17:16] <jim__> aw
[17:17] <jim__> ill read into this
[17:17] <jim__> i troubled you enough :)
[17:17] <jim__> thanks again for explaining the modular audio components, and how to GET SOUND :)
[17:17] <ailo> np
[17:18] <jim__> cu around
[19:28] <promis> Hello, I haeving problems with firewire audio card, jackd wont start saying: firewire ERR: Could not start streaming threads /Cannot start driver /JackServer::Start() failed with -1. Ffado mixer works, so I guess ffado is ok. Card works with 10.04, but in 12.04 fails. Jackd works with other PCs and 12.04, but fails on this one.
[19:29] <promis> Tried two different NEC firewire controlers
[19:30] <promis> jackd is 1.9.8. libffado is 2.999 (2.0.1) all default for 12.04
[19:30] <promis> Card is Edirol FA-66
