| plain-user | fresh ubuntu install. slightly noobish at the desk. two soundcards: internal and external usb m-audio fast track. task: 1) use internal card for skype. 2) use external card for all other audio processing guitar input/big speakers or headphones from card playback. | 12:01 |
|---|---|---|
| holstein | plain-user: is that a statement? | 13:09 |
| plain-user | i forgot to add one key word to that statement. thanks for reminding. | 13:12 |
| plain-user | HOW?! | 13:12 |
| plain-user | +D | 13:13 |
| holstein | plain-user: pulse will be using the internal card | 13:31 |
| holstein | for me, i have a firewire device and pulse runs on the internal card | 13:32 |
| holstein | when i run the FW device, JACK takes that over and leaves pulse running on the internal card | 13:32 |
| holstein | JACK is not something that i use trivially like that though | 13:32 |
| holstein | i use JACK when i need it | 13:32 |
| holstein | and turn it off when im not using it | 13:32 |
| plain-user | what i'm missing is the concept. i must have a device per sound server and one of the servers being default? | 13:40 |
| holstein | ? | 13:42 |
| holstein | this is linux | 13:42 |
| holstein | theres no *must* | 13:42 |
| holstein | you are implying doing pro audio | 13:42 |
| holstein | that means you probaly want to use JACK | 13:42 |
| plain-user | i dont know how ) | 13:43 |
| holstein | and you'll want to use that with the better hardware, that fast track | 13:44 |
| holstein | plain-user: sure... youll need to learn to use JACK | 13:44 |
| holstein | pulse will "just work" out of the box with the internal hardware | 13:44 |
| holstein | if it doesnt, then something is wrong with the hardware, or the support is not there | 13:45 |
| holstein | plain-user: what i would suggest if you are new to linux/audio is... | 13:45 |
| holstein | get the normal ubuntu | 13:45 |
| holstein | install that | 13:45 |
| plain-user | are there any articles that explain the concepts of what is what, or i need to read pages of pages about this, this and that, then build a wrong understanding in my brain, start using it and find myself lost. | 13:45 |
| holstein | use it with the internal hardware | 13:45 |
| holstein | get a live CD | 13:45 |
| holstein | sometihng like AVlinux | 13:45 |
| holstein | play with that with JACK and the USB hardware | 13:45 |
| holstein | plain-user: sure, there are nothing but articles about how JACK works with *some* kind of hardware | 13:46 |
| holstein | but, its all a bit technical, and different depending on what you have | 13:46 |
| holstein | again, i suggest... | 13:46 |
| holstein | install just plain normal ubuntu | 13:46 |
| holstein | play with it | 13:46 |
| holstein | test with LIVE discs til you learn how JACK works | 13:47 |
| holstein | then, you can always add whatever you want to that vanilla ubuntu install | 13:47 |
| holstein | JACK or whatever | 13:47 |
| plain-user | i already installed studio in hope that it already comes with configured jack the almighty and real-time kernel. | 13:47 |
| holstein | plain-user: you dont need a real-time kernel | 13:47 |
| holstein | mose folks dont | 13:47 |
| holstein | the only thing you need that for is low-latency | 13:47 |
| holstein | doing live effects processing | 13:47 |
| holstein | or playing software synthesisers live | 13:48 |
| holstein | other than that, its really just more hassle than its worth | 13:48 |
| plain-user | yes, that's what i want - use an instrument effect over my line-in signal. | 13:48 |
| holstein | plain-user: right, and thats *not* trivial | 13:48 |
| holstein | i wouls suggest *not* starting there | 13:48 |
| holstein | would | 13:48 |
| holstein | thats what i would call "advanced" | 13:49 |
| holstein | if you already have US installed, then i would try and get JACK running on the internal hardware | 13:49 |
| holstein | then the USB hardware | 13:49 |
| holstein | just get used to configuring JACK and starting/stopping it | 13:50 |
| plain-user | well it's already here on the hard drive installed an happy. jumping from distro to distro is noobish, that's what i was doing for the last few years, using the system just for basic home usage. | 13:50 |
| holstein | noobish? | 13:50 |
| holstein | i think its a great way to troubleshoot | 13:50 |
| holstein | especially with live CD's | 13:50 |
| holstein | you dont have to install/change the current setup | 13:50 |
| holstein | and you get to see what the hardware is like with different software | 13:51 |
| plain-user | that's when you know what you do, not like me - just guessing things and doing basic setup, crawl around. | 13:51 |
| holstein | a kernel rev can totally break, or fix support for some hardware | 13:51 |
| plain-user | well, yes... | 13:51 |
| holstein | live CD's are an easy way to see whats going on | 13:51 |
| holstein | for us, kernel versions, and ALSA versions can really make or break it | 13:52 |
| holstein | and you can fuss around for a long time and not get anywhere... | 13:52 |
| plain-user | well my card is very simple usb fast track m-audio. and internal audio is also quite straight-forward. | 13:52 |
| holstein | plain-user: lol | 13:52 |
| holstein | if *any* of this were simple/straight forware, you wouldnt be here ;) | 13:52 |
| holstein | again, i would start slow | 13:53 |
| holstein | i would suggest taking some time starting/stopping JACK on both your devices | 13:53 |
| holstein | starting with the internal one | 13:53 |
| plain-user | what about compiling the kernel with the right drivers that do work.. that's the other way around it isnt' it. | 13:53 |
| holstein | ? | 13:53 |
| plain-user | ok. | 13:53 |
| holstein | i use a realtime kernel from PPA | 13:53 |
| holstein | ubuntustudio doesnt have an RT kernel right now | 13:54 |
| holstein | hopefully in the 11.10 release we have a -lowlatency one | 13:54 |
| holstein | the PPA i use is falks ppa from KXstudio | 13:54 |
| plain-user | so my learning process: get my head around jack, and use it on both my cards. | 13:55 |
| holstein | well, to be more presice | 13:56 |
| holstein | learn to use it on the internal card first | 13:56 |
| holstein | then, you dont ever have to run it there again | 13:56 |
| holstein | that'll be easier (probably) | 13:56 |
| plain-user | jack isn't the sound server by itself, or am i wrong? | 13:56 |
| holstein | plain-user: dont think of JACK as a sound server | 13:56 |
| holstein | its not a replacement to pulse or alsa really | 13:56 |
| holstein | it just needs the audio hardware too, and cant typically run at the same time as pulse | 13:57 |
| plain-user | ok. what is sound server: alsa and pulseaudio? and i have pulse installed and running. it can run one card at a time, is it? | 13:57 |
| holstein | im not sure what all pulse is capable of | 13:58 |
| holstein | its all linux | 13:58 |
| holstein | so, realistically, the answer is *always* yes | 13:58 |
| plain-user | is it same like in windows i had asio and whenever i had guitarrig, all the other sounds including media player were off without sound? | 13:58 |
| holstein | if you want to run 3 cards with differnt servers on each, its all open code, so you have but to code it | 13:58 |
| holstein | or, if you want alsa to see a bunch of different cards as one, theres a way to do that | 13:59 |
| holstein | plain-user: its not going to be helpful to think about windows | 13:59 |
| holstein | anyways... i gotta run | 13:59 |
| plain-user | i know, i'm just remembering the issue i had recently in windows that was one sound instance per app | 14:00 |
| holstein | plain-user: let me know when you have about 20 minutes, and you are in front of the computer | 14:00 |
| holstein | we'll get JACK up and running | 14:00 |
| plain-user | holstein, thank you. of course run, we shall talk later, if it's ok. | 14:00 |
| holstein | plain-user: yeah, the only limits in linux are the actual hardware limitations | 14:00 |
| holstein | and you're imagination/coding skills | 14:00 |
| holstein | its all open | 14:00 |
| holstein | so, in theory, anything is possible | 14:01 |
| plain-user | that's why i want to nail it : one card for skype, other for guitar. | 14:01 |
| holstein | right, but you just stop JACK, and use skype with pulse | 14:01 |
| holstein | OR, use some kind of pulse to JACK bridging | 14:02 |
| holstein | or, use something other than skype like mumble | 14:02 |
| plain-user | what else i read: what is alsa and pulse and how they work, then jack and play with those. | 14:02 |
| holstein | there are tons of options with FOSS | 14:02 |
| holstein | you just have to play around with them | 14:02 |
| holstein | and ask questions :) | 14:02 |
| plain-user | yes | 14:02 |
| holstein | anyways... BBL... we'll catch up sometime soon | 14:03 |
| plain-user | ok. thank you again. talk to you later. ! | 14:03 |
