[17:29] <wip> hi everyone, i just tested 12.04 live cd and it is normal that when i start jack i see pulseaudio bridge but no sound come out of it (from audacius)
[17:31] <ailo> wip: You'll need to make pulseaudio use jack as the output from the pulseaudio mixer
[17:32] <ailo> You can open the mixer from the volume control applet
[17:32] <wip> ailo: from the release note: Pulse Audio <-> JACK bridging enabled by default
[17:33] <ailo> wip: It is enabled
[17:33] <wip> ailo: ok i see
[17:33] <ailo> But in order for pulseaudio to send audio to jack, you need to set it to do so
[17:33] <wip> ailo: if i want to always use jack is it possible to make it permanent?
[17:34] <ailo> wip: It is, but there's no gui setting that let's you do that
[17:34] <ailo> You'll need a script
[17:35] <ailo> Haven't tried to do that myself, but I assume you need to: 1. start jack, 2. set pulseaudio to use jack sink/source
[17:35] <wip> ailo: thanks, will come back when it's installed on my computer
[17:35] <ailo> I don't recommend using the bridge at really low latencies
[17:35] <ailo> But otherwise it works pretty well
[17:35] <wip> ailo: my last question is: the kernel is preempt and lowlatency (nice!) is there any problem using it with nvidia-current?
[17:35] <ailo> No problems
[17:35] <wip> excellent!
[17:36] <ailo> It's basically the same as -generic, only it performs about the same as a realtime kernel
[18:45] <Patou> hi
[18:45] <Patou> does anyone can help me pls?
[18:45] <Patou> i search some hardware advice for a new computer
[18:46] <Patou> i don't know which type of cpu or motherboard i have to buy
[18:50] <ailo> Patou: I don't think you should have any problems with most hardware
[18:50] <ailo> Are you going to use it to make music?
[18:51] <ailo> My last computer was very cheap. About 300$ in parts
[18:52] <ailo> I think you should be able to get something 64 bits, above 4 cores, above 4GB memory for not much more today
[18:52] <Patou> okay
[18:52] <Patou> it's for a home studio
[18:52] <Patou> something little
[18:53] <Patou> just with friends to record some reggae music )
[18:53] <Patou> =)*
[18:53] <ailo> Don't think you need much. The audio device is the most important
[18:53] <Patou> yeah i think so
[18:56] <Patou> i think about an amd cpu
[18:57] <Patou> it's cheaper than intel
[19:02] <ailo> Patou: I heard once that one may be better than the other, depending on the price range
[19:03] <ailo> Don't know myself. I just get something not too expensive, but still powerful enough to do everything I need it for
[19:03] <ailo> Graphic cards take care of graphics, so you don't really need a lot of cpu power
[19:03] <ailo> RAM is cheap
[19:03] <Patou> yep
[19:04] <Patou> motherboard depends on cpu
[19:28] <wip> Patou: as far as the soundcard do you have something already?
[19:28] <Patou> no i start a new computer
[19:29] <Patou> i will maybe have a very old computer
[19:29] <wip> do you want an external soundcard or internal?
[19:29] <Patou> internal i think
[19:30] <wip> hum... i recommand an external soundcard with line (1/4) input for instruments and if you have voice maybe also XLR (phantom power input)
[19:30] <wip> but of course you can record with a simple line in ;)
[19:30] <Patou> okay
[19:30] <Patou> it's for a home studio
[19:30] <Patou> with 2 or 3 friends
[19:30] <Patou> nothing profesional
[19:31] <Patou> and we have a short budget
[19:31] <Patou> (sry for my english i'm french...)
[19:31] <Patou> but i take note of your advice
[19:31] <wip> i am too
[19:31] <ailo> Most usb devices will only work in 48kHz/24bits, so it's a good idea to have a look at what you need and which devices have full support
[19:32] <Patou> yeah i didn't think about it
[19:32] <wip> something like that should work fine! http://www.ebay.ca/itm/M-Audio-Fast-Track-Pro-USB-Audio-Interface-/330750821303?pt=LH_DefaultDomain_0&hash=item4d024903b7#ht_500wt_1361
[19:32] <ailo> Most usb devices support usb 1.1, which means stereo 44.1, maybe 48kHz 16 bits
[19:32] <ailo> Oh, yeah. Not 24 bits, as I said earlier. I meant 16 bits
[19:33] <ailo> The fast track is supposed to have full support, but I wonder how well it performs in low latencies
[19:33] <wip> but always double and triple check that the soundcard is supported by ALSA / PulseAudio
[19:33] <wip> internal or external it doesn't matter
[19:33] <len-dt> Some music stores will rent interfaces.
[19:33] <ailo> pci devices are very well supported
[19:34] <Patou> (afk toilets i'll be back soon^^)
[19:34] <wip> i am pretty happy with my firepod 1010. i can get pretty decent low latency (8ms)
[19:34] <len-dt> I had trouble getting the fast track to work for me... but maybe I didn't spend enough time at it. I could see it but got no sound.
[19:34] <wip> but it's firewire...
[19:35] <wip> len-dt: oh! thx for the info
[19:35] <wip> len-dt: i tought that maudio was well supported in linux
[19:35] <len-dt> I have a delta 66 that works well, but it is pci
[19:36] <ailo> There's no doubt that the fast track is supported. But there's always the question how low latencies can you get with it
[19:36] <len-dt> The usb  stuff is not so well supported, but it is getting there. With the fast track I was trying it in the store with my netbook and so didn't have time to find out any tricks to get it to work
[19:37] <len-dt> I think there is a config file that needs to be set up in alsa for it.
[19:38] <Patou> (i'm back!)
[19:39] <ailo> There's some talk about it here http://joegiampaoli.blogspot.se/2011/06/m-audio-fast-track-pro-for-debian-linux.html
[19:40] <len-dt> Thanks ailo it says it needs a rolled kernel.
[19:41]  * len-dt means to make it worth spending more than a usb 1.1
[19:42] <ailo> I don't think so though
[19:43] <len-dt> ailo, just reading the page you showed.
[19:44] <ailo> You don't need to build a new kernel. He does mention adding a conf file to /etc/modprobe.d
[19:44] <holstein> any p4 with a gig of ram would be quite adaquate for any audio
[19:44] <len-dt> Ya, I am seeing that our low latency kernel seems to have what he sugests.
[19:45] <ailo> holstein: I would agree, if using an older system. Firefox alone needs at least that
[19:45] <holstein> maybe when you start loading up 50+ tracks on a large studio session, but even then, the sound card you dont want to afford will break down before the system
[19:45] <len-dt> holstein, ya, the extra memory does seem to help with some things...
[19:45] <ailo> Also, 64 bit systems need a bit more RAM
[19:46] <len-dt> I don't think my p4 is 64 bit...
[19:46] <holstein> if you didnt spend $1200+ on a sound card, you dont need a new computer
[19:46] <ailo> 2GB as a bare minimum with 12.04 IMO
[19:46] <holstein> just my opinion
[19:47] <ailo> I wasn't referring to P4. Just saying that today, if you buy a processor, it will most likely be 64 bits
[19:47] <ailo> In fact, it might be the default when you download the next release of Ubuntu, instead of the 32 bit version
[19:48] <len-dt> Ya, my p4 is 8years back. It is fine for recording, it is the softsynths for live work where it fails.
[19:48] <ailo> If you *only* use the PC for music, than it's a bit different
[19:48] <ailo> I wouldn't recommend anyone to use a P4 with the lates release of Ubuntu though. Not for normal desktop use
[19:49] <holstein> well, i would recommend buying a new box, but you dont need one
[19:50] <holstein> anyways... i gotta run o/
[19:51] <len-dt> There are people using atom stuff... on purpose for audio.
[19:53] <ailo> The processor in itself is not the problem, but what comes with it. With a P4, you likely have an old MB, which maybe supports as high as 2GB, but older and more expensive RAM. Also, no way to get cheap modern graphics, as it the MB doesn't have pci-E
[19:54] <ailo> With atom, you're running a more modern computer, and you get all those things for a low price
[19:55] <ailo> I was using a P3 not that long ago, but I could never use it for normal desktop use
[19:55] <len-dt> Yup. my p4 will take 4g, but my nvidia card is a pain. I can't replace it just now though.
[19:56] <ailo> A passive graphic card, that has all you ever want, except the bleeding edge 3D stuff is only something like 40-50$
[19:56] <ailo> pic-E, that is
[19:56] <ailo> pci-E*
[19:57] <len-dt> Don't most MB come with video? or just really cheap stuff?
[19:57] <ailo> Some do. And they work too of course
[19:58] <ailo> some processors have integrated graphics as well
[19:59] <len-dt> Some may not play fairly with buses, I think that is the problem with my wireless.
[19:59] <ailo> Mainly a problem with laptops AFAIK
[20:00] <ailo> But I guess any MB may be prone to that
[20:00] <ailo> Only, if you buy the MB separately, it usually is a bit more configurable
[20:01] <len-dt> My guess is that anything with the PCI slots I want would be ok.
[20:01] <ailo> Hard to find a MB with more than 2 slots these days :)
[20:01] <ailo> I've seen some with 3, so there are options I guess
[20:02] <len-dt> mine has 5, more than I need, but I would want two plus inernal video.
[20:03] <ailo> That's what I have, but the video is a bit old now. nvidia 7250. It's ok for average desktop use
[20:04] <len-dt> I don't need/want fancy graphics, but am starting to think two screens might be nice.
[20:04] <ailo> I'm getting a nvidia 610 shortly, probably. Cheap, with all the modern specs, only not the best for newer 3D games
[20:04] <ailo> I've gotten used to using my LCD TV as monitor
[20:05] <ailo> Seemed strange at first, but I quickly got used to it
[20:05] <len-dt> I have kids... I would never get to use a tv...
[20:06] <ailo> Haven't used AMD graphics a lot. The one time I had a chance, it worked well, except for multiple monitors
[20:06] <ailo> nvidia has been solid for me for years, all though there are a few bugs now and again. Some that crashes the system
[20:07] <len-dt> How good are USB video IFs?
[20:07] <ailo> Never tried one
[20:09] <len-dt> The RME guys used one in one of their demos (actually two of them) so they could have enough room for 120 or more channels.
[20:09] <len-dt> 3 screens
