| ale` | hi, are there any disadvantages in using ubuntustudio as a desktop system instead of the normal ubuntu? | 01:23 |
| persia | ale`, No. | 01:24 |
| persia | ale`, The exact same software is available, from the exact same repositories. Only the defaults differ. | 01:25 |
| 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 :-/ | 01:29 |
| persia | There's no point. | 01:30 |
| persia | Kubuntu and Ubuntu Studio are both flavours: they use the same repos, etc. | 01:30 |
| 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? | 01:31 |
| 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. | 01:32 |
| persia | I don't believe there is a realtime kernel available for maverick, but it's not necessary for most uses. | 01:33 |
| ale` | mh, reading the website I was thinking having a realtime kernel was the most important difference.. seems important for multitrack recording | 01:35 |
| persia | Really, it's not. | 01:36 |
| ale` | persia: I see :-) | 01:36 |
| 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. | 01:37 |
| 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. | 01:38 |
| 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 :-) | 01:39 |
| ale` | If it can handle some overdubbing and record while listening to the other tracks it's enough | 01:40 |
| persia | A 700MHz Pentium III could do that without a realtime kernel. You should have no issues at all. | 01:41 |
| ale` | great :-) | 01:42 |

| 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? | 22:16 |
| plumstead21 | when I start JACK I get the following in the messages window | 22:17 |
| 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: | 22:18 |

| holstein | hey plumstead21 | 22:37 |
| holstein | i'll be available in a minute | 22:37 |
| Submarine | plumstead21, I bet pulseaudio is running | 22:48 |
| Submarine | try | 22:49 |
| Submarine | echo 'suspend 1' | pacmd | 22:49 |
| holstein | plumstead21: i would run, in a terminal | 22:50 |
| 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 | 22:51 |
| 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 | 22:52 |
| 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 | 22:53 |
| persia | Makes sense. I didn't think permissions were still a common issue. Ignore me :) | 22:54 |
| 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 | 22:55 |
| plumstead21 | hello holstein, persia, Submarine | 23:00 |
| plumstead21 | thanks for your help | 23:00 |
| plumstead21 | after doing pasuspender -- qjackctl then starting, I get an unending stream of errors :$ | 23:05 |
| plumstead21 | JackAudioDriver::ProcessAsync: read error, skip cycle | 23:06 |
| plumstead21 | alsa_driver_xrun_recovery | 23:06 |
| plumstead21 | and then that repeats... | 23:06 |
| plumstead21 | same if I run sudo qjackctl | 23:07 |
| holstein | plumstead21: interesting | 23:08 |
| holstein | what are your setting? | 23:08 |
| holstein | settings | 23:08 |
| 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' | 23:09 |
| 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 | 23:11 |
| holstein | plumstead21: hmmm | 23:16 |
| holstein | plumstead21: i dont think its the modem | 23:19 |
| holstein | you can disable it int he bios though right? | 23:19 |
| 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 | 23:20 |
| plumstead21 | OK, thanks - that's something! | 23:21 |
| holstein | plumstead21: this is 10.10? | 23:21 |
| plumstead21 | holstein: yes | 23:22 |
