[00:15] <ScottL> ah, i see now where submarine thought that 48 was a multiple of 1khz :/
[01:23] <ale`> hi, are there any disadvantages in using ubuntustudio as a desktop system instead of the normal ubuntu?
[01:24] <persia> ale`, No.
[01:25] <persia> ale`, The exact same software is available, from the exact same repositories.  Only the defaults differ.
[01:29] <ale`> persia: is it hard to "upgrade" my kubuntu to ubuntu studio? Am I better off reinstalling the whole thing? My main use for linux is software development and I already have kunbuntu installed :-/
[01:30] <persia> There's no point.
[01:30] <persia> Kubuntu and Ubuntu Studio are both flavours: they use the same repos, etc.
[01:31] <persia> If you want the Ubuntu Studio desktop, you can install the ubuntustudio-desktop package.  If you just want some of the tools, install the tools (or a set of tools, like ubuntustudio-audio)
[01:31] <ale`> persia: I was thinking about audio setup and real time kernel. Are those easy to get the same as in ubuntustudio?
[01:32] <persia> The audio setup is mostly the same, although Ubuntu Studio tends to use JACK based tools.
[01:32] <persia> Installing any tool that uses JACK will get you JACK automatically.
[01:32] <persia> Although installing ubuntustudio-audio will be sure to get you the extra useful tools.
[01:33] <persia> I don't believe there is a realtime kernel available for maverick, but it's not necessary for most uses.
[01:35] <ale`> mh, reading the website I was thinking having a realtime kernel was the most important difference.. seems important for multitrack recording
[01:36] <persia> Really, it's not.
[01:36] <ale`> persia: I see :-)
[01:37] <persia> So, it's like this.
[01:37] <persia> If you try to run more effects or processing than your computer can handle, realtime and non-realtime have different side effects.
[01:38] <persia> With a realtime kernel, you end up maxing out CPU, and just dropping samples.
[01:38] <persia> With a non-realtime kernel, you may end up not completing some processing, while completing other processing, but with JACK's sample-accuracy guarantee, you end up dropping samples anyway.
[01:39] <persia> If you have very underpowered hardware, you may find that you benefit, but there have been few reports of that sort of problem recently.
[01:39] <ale`> mh, I guess I won't have any problems then, not doing any serious work :-)
[01:40] <ale`> If it can handle some overdubbing and record while listening to the other tracks it's enough
[01:41] <persia> A 700MHz Pentium III could do that without a realtime kernel.  You should have no issues at all.
[01:42] <ale`> great :-)
[03:12] <ryjyd1> hello, anyone got their ears on?
[22:16] <plumstead21> Hello, I wonder if you can help? I've installed Ubuntu Studio on a spare laptop (Toshiba Satellite Pro A120) and can't get JACK to start. Think it could be because of the dial-up modem?
[22:17] <plumstead21> when I start JACK I get the following in the messages window
[22:18] <plumstead21> creating alsa driver ... hw:0|hw:0|1024|2|44100|0|0|nomon|swmeter|-|32bit
[22:18] <plumstead21> Using ALSA driver HDA-Intel running on card 0 - HDA ATI SB at 0xffaf8000 irq 41
[22:18] <plumstead21> the playback device "hw:0" is already in use. Please stop the application using it and run JACK again
[22:18] <plumstead21> aplay -l gives the following:

[22:37] <holstein> hey plumstead21
[22:37] <holstein> i'll be available in a minute
[22:48] <Submarine> plumstead21, I bet pulseaudio is running
[22:49] <Submarine> try
[22:49] <Submarine> echo 'suspend 1' | pacmd
[22:50] <holstein> plumstead21: i would run, in a terminal
[22:51] <holstein> sudo qjackctl
[22:51] <holstein> and see if JACK starts
[22:51] <persia> Uh, why sudo?  qjackctl really shouldn't need that.
[22:51] <holstein> persia: trouble-shooting
[22:51] <holstein> if it starts sudo
[22:51] <persia> Won't running JACK as root cause problem with client connects?
[22:51] <holstein> persia: yes
[22:52] <persia> I'd try `pasuspender -- qjackctl` first.
[22:52] <holstein> *as a trouble-shooting step
[22:52] <holstein> sudo qjackctl can be run
[22:52] <holstein> i do not suggest running it as root
[22:52] <persia> Heh, OK.  If it helps you :)
[22:52] <holstein> persia: it helps me everytime
[22:52] <holstein> with firewire devices
[22:53] <holstein> and troubleshooting permission
[22:53] <holstein> AND getting JACK configured properly
[22:53] <holstein> so i can tell if it will *in theory* start
[22:53] <holstein> IF the permissions are correct
[22:54] <persia> Makes sense.  I didn't think permissions were still a common issue.  Ignore me :)
[22:55] <holstein> hehe
[22:55] <holstein> persia: nah, i should, and try to be clear
[22:55] <holstein> that it should not be a regular thing
[22:55] <holstein> running JACK as root
[23:00] <plumstead21> hello holstein, persia, Submarine
[23:00] <plumstead21> thanks for your help
[23:05] <plumstead21> after doing pasuspender -- qjackctl then starting, I get an unending stream of errors :$
[23:06] <plumstead21> JackAudioDriver::ProcessAsync: read error, skip cycle
[23:06] <plumstead21> alsa_driver_xrun_recovery
[23:06] <plumstead21> and then that repeats...
[23:07] <plumstead21> same if I run sudo qjackctl
[23:08] <holstein> plumstead21: interesting
[23:08] <holstein> what are your setting?
[23:08] <holstein> settings
[23:09] <plumstead21> which ones? I don't think I've configured anything as such, it's a fresh install
[23:09] <holstein> in jack control
[23:09] <holstein> under 'setup'
[23:11] <plumstead21> OK...
[23:11] <plumstead21> Realtime checked; Frames/Period 1024; Sample Rate 44100;Periods/Buffer 2;Port Maximum 256; Timeout 500
[23:11] <plumstead21> Start Delay 2; everything else is disabled or set as default
[23:16] <holstein> plumstead21: hmmm
[23:19] <holstein> plumstead21: i dont think its the modem
[23:19] <holstein> you can disable it int he bios though right?
[23:20] <plumstead21> I couldn't find a way of disabling in the bios. I don't think the modem driver is enabled though as it's unchecked in System > Administration > Additional Drivers
[23:20] <persia> Shouldn't be the modem: that would just appear as a secondary card: as long as the right card is selected in qjackctl, it ought do the right thing.
[23:20] <holstein> yeah, i dont think its that
[23:21] <plumstead21> OK, thanks - that's something!
[23:21] <holstein> plumstead21: this is 10.10?
[23:22] <plumstead21> holstein: yes
