| Kerio2 | hello | 14:42 |
| Kerio2 | i have just installed ubuntu studio and am trying to choose a rt kernel but i cant find one. is it possible to install one from synaptic? | 14:43 |
| AutoStatic | Hello Kerio2, Ubuntu Studio 10.10? | 14:47 |
| Kerio2 | yes | 14:48 |
| AutoStatic | 10.10 doesn't have a realtime kernel | 14:48 |
| Kerio2 | really? :( | 14:48 |
| Kerio2 | could you recommend one that does? | 14:49 |
| AutoStatic | 10.04 | 14:49 |
| AutoStatic | https://wiki.ubuntu.com/RealTime | 14:49 |
| Kerio2 | allright, will try it! thank you for your help AutoStatic | 14:50 |
| AutoStatic | You're welcome | 14:50 |
| AutoStatic | hope it isn't too much of a bummer that you have to downgrade | 14:51 |
| Kerio2 | installing on virtual machine so no biggie :) | 14:51 |
| Kerio2 | trying it out before i go live | 14:51 |
| AutoStatic | :) | 14:51 |
| Kerio2 | looking for a good kernel to run counter strike gameserver on | 14:52 |
| Kerio2 | i have tried http://wiki.fragaholics.de/index.php/EN:Linux_Kernel_Optimization several times but i cant get it to work | 14:53 |
| Kerio2 | so i am looking for other options | 14:53 |
| * persia idly mentions that running an RT kernel in a VM is likely to be *slower* and have *more* latency than a -generic kernel, especially if the kernel for the host machine isn't RT (but even if it is). | 15:34 | |
| Mystek | Just curious is it possible to run the jackd through a VM? | 18:18 |
| persia | Yes, but expect fairly high latency | 18:18 |
| holstein | you can dual boot easy enough | 18:19 |
| Mystek | I know, I just hate having to reboot and I tinker more with linux. | 18:20 |
| holstein | i would suspect tinkering with the VM would be more of a drag than rebooting | 18:20 |
| holstein | depending on what your trying to do | 18:20 |
| Mystek | The problem is this computer's soudncard is causing me problems in even Windows 7, otherwise I only have a legacy m-audio device | 18:20 |
| persia | Or run whatever you use less in the VM | 18:20 |
| persia | Which card? | 18:20 |
| Mystek | So I've never got much performance out of linux | 18:21 |
| Mystek | It's a Realtek HD Audio | 18:21 |
| Mystek | 7.1 | 18:21 |
| Mystek | Plus I'm running 64 bits | 18:21 |
| Mystek | So I had to basically uninstall the drivers and then let Windows handle them | 18:21 |
| Mystek | But I get a PCM error from VirtualBox and Jack crashes | 18:22 |
| persia | Try with a liveCD: that ought work fine. Realtek is getting better and better support these days. | 18:22 |
| Mystek | On Windows it was pretty glitchy until I removed the drivers | 18:23 |
| Mystek | I should try the m-audio card | 18:24 |
| persia | Yeah, well. Different driver writers, different priorities. I doubt anyone here can speak for Windows kernels. | 18:24 |
| Mystek | It's weird because OSS works I believe | 18:24 |
| Mystek | Gnome works with OSS right or is this a PulseAudio thing? | 18:26 |
| Mystek | Sorry I have a BSD background | 18:26 |
| holstein | Mystek: cool | 18:28 |
| holstein | that should serve you well | 18:28 |
| holstein | Mystek: what maudio card is it? | 18:28 |
| Mystek | Quattro | 18:28 |
| holstein | the realtik should work fine | 18:28 |
| holstein | i have one | 18:28 |
| holstein | a couple acutally | 18:29 |
| Mystek | Dualbooting? | 18:29 |
| holstein | and they work fine | 18:29 |
| holstein | nah | 18:29 |
| holstein | just ubuntu | 18:29 |
| holstein | this is where i check | 18:30 |
| holstein | http://www.alsa-project.org/main/index.php/Matrix:Main | 18:30 |
| holstein | i usually check there | 18:30 |
| persia | By default, Ubuntu is JACK or Pulse running against an ALSA backend. | 18:30 |
| holstein | try live CD's | 18:30 |
| holstein | run lspci | 18:30 |
| holstein | aplay -l | 18:30 |
| Mystek | Ok pulseaudio is running | 18:30 |
| holstein | arecord -l | 18:30 |
| Mystek | I couldn't kill it | 18:30 |
| persia | `pulseaudio -k` should work. | 18:30 |
| holstein | try and get an idea of compatibility before installing | 18:30 |
| holstein | launching jack control should suspend pulse right? | 18:31 |
| holstein | or is that changed now in maverick? | 18:31 |
| Mystek | Ok my card came up in aplay | 18:31 |
| Mystek | JackAudioDriver::ProcessAsync: read error, skip cycle Released audio card Audio0 | 18:32 |
| Mystek | That's what happens | 18:32 |
| Mystek | In qjackctl | 18:33 |
| persia | This is on HW, or on the VM? | 18:33 |
| Mystek | And also when I run the command | 18:33 |
| Mystek | Through the VM | 18:33 |
| persia | So, first thing to hunt is the quality of the ALSA drivers for the emulated soundcard. My experience is that they tend to have limited coverage. | 18:34 |
| persia | Which soundcard are you emulating? | 18:34 |
| Mystek | card 0: I82801AAICH [Intel 82801AA-ICH], device 0: Intel ICH [Intel 82801AA-ICH] | 18:34 |
| Mystek | But I think it might have happened with the SB too? | 18:35 |
| persia | That ought be OK. Hrm. | 18:35 |
| holstein | yeah | 18:35 |
| holstein | it should | 18:35 |
| holstein | Mystek: is this maverick? | 18:35 |
| holstein | i would suggest getting a lucid live CD | 18:36 |
| persia | Which VM engine are you using? | 18:36 |
| holstein | and run those commands | 18:36 |
| Mystek | VirtualBox | 18:36 |
| * persia agrees with holstein: working with real hardware is much more likely to be a pleasant experience for audio | 18:36 | |
| Mystek | I guess I can just dual boot | 18:36 |
| persia | Does booting into Ubuntu work, and it only has issues in the VM? | 18:36 |
| Mystek | Not like I don't have a TB and a half :P | 18:36 |
| Mystek | Yeah it's working great in the VM | 18:37 |
| Mystek | Sound works | 18:37 |
| holstein | Mystek: run the live CD | 18:37 |
| Mystek | Just can't get Jack running | 18:37 |
| holstein | and feel free to ask questions here before you 'pull the trigger' | 18:37 |
| persia | JACK exercises the audio drivers a bit more than some other things :) | 18:37 |
| Mystek | Would using portaudio work in the VM? | 18:38 |
| Mystek | Let's see if I can compile a CS score | 18:39 |
| Mystek | I was just curious about what I could do in the VM | 18:40 |
| holstein | most anything | 18:40 |
| holstein | just slower | 18:40 |
| holstein | and probably not pro-audio | 18:40 |
| persia | Everything should work fine, to the limits of the drivers, *except* that running anything in a VM is inherently is in a separate continuity, so you won't be able to trust any timings. | 18:40 |
| holstein | ive never even considered trying it | 18:40 |
| Mystek | I was also jsut trying to see where the state of software was at. I haven't booted Linux in like years... | 18:41 |
| persia | It got better :) | 18:41 |
| Mystek | Are VSTs supported better? | 18:41 |
| holstein | linux native vst's run great ;) | 18:42 |
| persia | There's some support for foreign VSTs, under WINE, but it's a bit awkward. | 18:42 |
| holstein | ask whoever makes the vst's | 18:42 |
| Mystek | I guess it would just make more sense to dual boot | 18:48 |
| Mystek | I'm just rather busy and like to multitask | 18:48 |
| Mystek | But just playing around in here, gave me a new idea | 18:49 |
| holstein | yeah, run windows in VM ;) | 18:50 |
| Mystek | I'm not that sold on Linux | 18:51 |
| Mystek | I still like Windows for a lot of things | 18:51 |
| Mystek | A problem with Linux is that it's almost too customizable | 18:52 |
| Mystek | So you get distracted a lot and blobbing can still be an issue | 18:52 |
| Mystek | And of course noobs :] | 18:52 |
| Mystek | Or devels having to take time to support | 18:53 |
| persia | Folks who do support mostly volunteer, so don't worry about that. | 18:53 |
| holstein | yeah | 18:53 |
| holstein | nothing like JACK though | 18:53 |
| holstein | for audio | 18:54 |
| persia | In Ubuntu, we tend towards opinionated defaults: all the choice is there behind the scenes, but we're happy to tell you how we think you should do it, so you don't have to do all the customisation. | 18:54 |
| holstein | i mean, i guess you can run JACK in windows and OSX | 18:54 |
| holstein | but the supported apps are not really there | 18:54 |
| Mystek | Well, what I'm really looking to do is work with portaudio | 18:54 |
| Mystek | But also make some cool stuff in the software that's available | 18:55 |
| Mystek | Which is why I'm here | 18:55 |
| Mystek | Even though I mainly develop for Windows | 18:55 |
| holstein | Mystek: glad you found us :) | 18:55 |
| Mystek | So what's the deal with Root now, is there no root? | 18:56 |
| Mystek | I noticed I could only sudo | 18:57 |
| persia | There's a root, but nobody uses it, and it has no password by default. | 18:58 |
| persia | root mostly just owns files. | 18:58 |
| Mystek | Alright off to install. Thanks, ttyl. | 19:09 |
| royvegard | After upgrading to 10.10 I no longer have access permission to my firewire Alesis MultiMix16. | 19:56 |
| holstein | royvegard: drag | 19:56 |
| holstein | JACK wont start? | 19:56 |
| holstein | try sudo qjackctl | 19:56 |
| holstein | just to make sure its permissions | 19:56 |
| persia | (note that if this works, there's still stuff to be done, as running in sudo means clients can't connect) | 19:57 |
| holstein | yeah, you dont want to run JACK as root normally | 19:57 |
| holstein | you have to run everything else as root, and thats not ideal | 19:58 |
| holstein | have a look at https://help.ubuntu.com/community/Firewire | 19:58 |
| royvegard | sudo works, and I can change the permissions of the /dev/fw*, but whenever i turn off my mixer /dev/fw is "recreated" | 19:58 |
| holstein | this is down the page a bit echo 'KERNEL=="raw1394", GROUP="video", MODE="0664"' | | 19:58 |
| holstein | sudo tee /etc/udev/rules.d/50-raw1394.rules | 19:58 |
| holstein | you'll see it there ^^^ at that link | 19:58 |
| holstein | that and sudo adduser royvegard audio | 19:59 |
| holstein | and | 19:59 |
| holstein | sudo adduser royvegard video | 19:59 |
| holstein | *should* do the trick | 19:59 |
| royvegard | I'll try that... | 19:59 |
| holstein | royvegard: works for me with a presonus firepod | 20:00 |
| persia | We really need to track down why. Users shouldn't need to be in the audio group anymore. | 20:00 |
| holstein | persia: i havent tried not adding in maverick | 20:00 |
| royvegard | BTW it worked fine on 10.04 | 20:00 |
| holstein | royvegard: i did an upgrade from karmic to lucid | 20:01 |
| holstein | and i had to redo those changes | 20:01 |
| persia | holstein, I'm sure there's still several leftovers: the kernel bits were fixed, but would need someone digging a fair bit through all the use cases to know it's no longer needed for userspace. | 20:02 |
| holstein | persia: when i get around to doing some natty test | 20:02 |
| holstein | i'll try and remember to go step by step | 20:02 |
| holstein | and try the firepod | 20:03 |
| holstein | in between each step | 20:03 |
| holstein | see what is not needed anymore | 20:03 |
| royvegard | holstein: Doesn't seem to work. Should there be two == after KERNEL? | 20:12 |
| holstein | royvegard: you'll need to logout and back in | 20:12 |
| holstein | royvegard: and yeah, check that link | 20:12 |
| holstein | echo 'KERNEL=="raw1394", GROUP="video", MODE="0664"' | | 20:12 |
| holstein | sudo tee /etc/udev/rules.d/50-raw1394.rules | 20:12 |
| holstein | OOPS | 20:12 |
| holstein | https://help.ubuntu.com/community/Firewire | 20:13 |
| holstein | its about half way down Ubuntu 10.04 (Lucid Lynx) and 10.10 (Maverick Meerkat) | 20:13 |
| holstein | Everything should just work if you paste this in your terminal, and reboot: | 20:13 |
| holstein | ^^ looks like that | 20:13 |
| holstein | i might have missed something in the copy and paste | 20:13 |
| royvegard | I got it to work by replacing raw1394 with fw1. | 20:26 |
| holstein | interesting | 20:27 |
| royvegard | Doy you have fw1 and fw0 in /dev ? | 20:27 |
| holstein | its very challening to keep a simple 'how-to' going | 20:27 |
| holstein | royvegard: i'll have to look | 20:27 |
| holstein | BUT, im running lucid | 20:27 |
| holstein | and that above as-is worked for my firepod | 20:28 |
| holstein | i'll look when i go boot everything up here in a while | 20:28 |
| royvegard | When I was running lucid it worked fine and I never checked if I had fw0 and fw1. It would be interesting to see if you have them, or if you only have raw1394. | 20:32 |
| persia | That's probably a side effect of the new FW stack, which is a good thing, because it can tell the difference between different device classes. | 20:39 |
| holstein | OH | 20:40 |
| holstein | maybe a step toward using multiple FW devices again :) | 20:40 |
| persia | Precisely. I think that landed for maverick, but I haven't played with it much yet (my firewire disk enclosure is somewhere in the boxes yet to be unpacked from my recent move) | 20:41 |
| Nils^ | hey. Next version without seq24, lilypond and audacity? | 22:59 |
| persia | That's the current idea. All three will be available on demand, just not present by default. | 23:00 |
| persia | seq24 is an *excellent* live sequencer. | 23:00 |
| persia | But there doesn't seem to be that many live users: most seem to want to use a sequencer for composition, and other tools are stronger at that. | 23:01 |
| holstein | Nils^: nothing is getting pulled from the repos | 23:01 |
| persia | lilypond produces beautiful scores, but it's been historically hard to maintain, and musescore has some handy features that make it easier for folks new to the tools. | 23:01 |
| persia | I forget why audacity was being dropped: someone might want to write up a use case for cleaning up audio to get it back. | 23:02 |
