[00:15] ah, i see now where submarine thought that 48 was a multiple of 1khz :/ [01:23] hi, are there any disadvantages in using ubuntustudio as a desktop system instead of the normal ubuntu? [01:24] ale`, No. [01:25] ale`, The exact same software is available, from the exact same repositories. Only the defaults differ. [01:29] 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] There's no point. [01:30] Kubuntu and Ubuntu Studio are both flavours: they use the same repos, etc. [01:31] 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] persia: I was thinking about audio setup and real time kernel. Are those easy to get the same as in ubuntustudio? [01:32] The audio setup is mostly the same, although Ubuntu Studio tends to use JACK based tools. [01:32] Installing any tool that uses JACK will get you JACK automatically. [01:32] Although installing ubuntustudio-audio will be sure to get you the extra useful tools. [01:33] I don't believe there is a realtime kernel available for maverick, but it's not necessary for most uses. [01:35] mh, reading the website I was thinking having a realtime kernel was the most important difference.. seems important for multitrack recording [01:36] Really, it's not. [01:36] persia: I see :-) [01:37] So, it's like this. [01:37] If you try to run more effects or processing than your computer can handle, realtime and non-realtime have different side effects. [01:38] With a realtime kernel, you end up maxing out CPU, and just dropping samples. [01:38] 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] 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] mh, I guess I won't have any problems then, not doing any serious work :-) [01:40] If it can handle some overdubbing and record while listening to the other tracks it's enough [01:41] A 700MHz Pentium III could do that without a realtime kernel. You should have no issues at all. [01:42] great :-) [03:12] hello, anyone got their ears on? === olinuxx_ is now known as olinuxx === charlie-tca__ is now known as charlie-tca [22:16] 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] when I start JACK I get the following in the messages window [22:18] creating alsa driver ... hw:0|hw:0|1024|2|44100|0|0|nomon|swmeter|-|32bit [22:18] Using ALSA driver HDA-Intel running on card 0 - HDA ATI SB at 0xffaf8000 irq 41 [22:18] the playback device "hw:0" is already in use. Please stop the application using it and run JACK again [22:18] aplay -l gives the following: [22:19] **** List of PLAYBACK Hardware Devices **** [22:19] card 0: SB [HDA ATI SB], device 0: ALC262 Analog [ALC262 Analog] [22:19] Subdevices: 0/1 [22:19] Subdevice #0: subdevice #0 [22:19] card 0: SB [HDA ATI SB], device 6: Si3054 Modem [Si3054 Modem] [22:19] Subdevices: 1/1 [22:19] Subdevice #0: subdevice #0 [22:37] hey plumstead21 [22:37] i'll be available in a minute [22:48] plumstead21, I bet pulseaudio is running [22:49] try [22:49] echo 'suspend 1' | pacmd [22:50] plumstead21: i would run, in a terminal [22:51] sudo qjackctl [22:51] and see if JACK starts [22:51] Uh, why sudo? qjackctl really shouldn't need that. [22:51] persia: trouble-shooting [22:51] if it starts sudo [22:51] Won't running JACK as root cause problem with client connects? [22:51] persia: yes [22:52] I'd try `pasuspender -- qjackctl` first. [22:52] *as a trouble-shooting step [22:52] sudo qjackctl can be run [22:52] i do not suggest running it as root [22:52] Heh, OK. If it helps you :) [22:52] persia: it helps me everytime [22:52] with firewire devices [22:53] and troubleshooting permission [22:53] AND getting JACK configured properly [22:53] so i can tell if it will *in theory* start [22:53] IF the permissions are correct [22:54] Makes sense. I didn't think permissions were still a common issue. Ignore me :) [22:55] hehe [22:55] persia: nah, i should, and try to be clear [22:55] that it should not be a regular thing [22:55] running JACK as root [23:00] hello holstein, persia, Submarine [23:00] thanks for your help [23:05] after doing pasuspender -- qjackctl then starting, I get an unending stream of errors :$ [23:06] JackAudioDriver::ProcessAsync: read error, skip cycle [23:06] alsa_driver_xrun_recovery [23:06] and then that repeats... [23:07] same if I run sudo qjackctl [23:08] plumstead21: interesting [23:08] what are your setting? [23:08] settings [23:09] which ones? I don't think I've configured anything as such, it's a fresh install [23:09] in jack control [23:09] under 'setup' [23:11] OK... [23:11] Realtime checked; Frames/Period 1024; Sample Rate 44100;Periods/Buffer 2;Port Maximum 256; Timeout 500 [23:11] Start Delay 2; everything else is disabled or set as default [23:16] plumstead21: hmmm [23:19] plumstead21: i dont think its the modem [23:19] you can disable it int he bios though right? [23:20] 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] 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] yeah, i dont think its that [23:21] OK, thanks - that's something! [23:21] plumstead21: this is 10.10? [23:22] holstein: yes
