| ollie_ | Hi, I'm in the process of trying to get my focusrite saffire interface working on ubuntu. I installed ubuntustudio-audio and ubuntustudio-audio-plugins, added myself to the audio group, started qjackctl and changed it to firewire, and clicked start, and i got sound for a bit. It momentarily pauses when new applications are opened, and it seems to have died completely when I was installing this irc client with apt. How do I get this working? | 02:09 |
|---|---|---|
| holstein | ollie_: you can ask [lsd] in #opensourcemusicians if you'd like | 02:12 |
| holstein | i am told it works out of the box in 12.04 | 02:12 |
| holstein | ollie__: you can ask [lsd] in #opensourcemusicians if you'd like | 02:13 |
| holstein | i am told it works out of the box in 12.04 | 02:13 |
| holstein | i have a firewire device and i typically troubleshoot as root | 02:13 |
| holstein | i dont leave JACK running all the time either, nor do i run pulse audio through it, but im told that works well now too | 02:13 |
| ollie__ | hm | 02:14 |
| holstein | i would open a terminal and run "gksudo qjackctl" | 02:14 |
| holstein | i would choose the firewire driver | 02:14 |
| holstein | i would choose settings like 1024/2 | 02:14 |
| holstein | under setup | 02:15 |
| ollie__ | yep | 02:15 |
| holstein | 1024 frames per period | 02:15 |
| ollie__ | I dont have a realtime kernel, should i untick realtime? | 02:15 |
| holstein | 2 periods per buffer | 02:15 |
| holstein | ollie__: you can try it.. it shouldnt make it fail, but try both if you are having issues | 02:15 |
| ollie__ | ok, now how do i test it? do i need to run my audio player as root? | 02:16 |
| holstein | ollie__: you can.. i typically just get it started though,a nd see that it starts | 02:16 |
| holstein | you could run something else as root if you want to hear something | 02:17 |
| ollie__ | it has started | 02:17 |
| holstein | then, troubleshoot permissions errors or whatever | 02:17 |
| holstein | you want to run it as a normal user ASAP | 02:17 |
| ollie__ | okay | 02:18 |
| ollie__ | I cant seem to make it make sound as root | 02:18 |
| ollie__ | I think i need to change the sound settings too | 02:18 |
| ollie__ | but it was working as a normal user | 02:18 |
| holstein | ollie__: maybe you dont have the speakers in properly? | 02:18 |
| holstein | ollie__: you shouldnt need to change any sound settings | 02:18 |
| ollie__ | im not actually using ubuntu per se, but a distro based on it | 02:19 |
| holstein | ollie__: kxstudio? | 02:19 |
| ollie__ | elementary os | 02:19 |
| holstein | shouldnt be anything there that is breaking our stuff | 02:19 |
| ollie__ | i had to change the sound device to jack in their settings panel | 02:19 |
| holstein | ollie__: you shouldnt have to | 02:19 |
| ollie__ | so i guess i would need to do that as root | 02:19 |
| holstein | ollie__: i would leave that be | 02:19 |
| ollie__ | ok | 02:20 |
| holstein | just start JACK, and use what tools you want with JACK | 02:20 |
| ollie__ | i will try as a normal user again | 02:20 |
| holstein | unless you want all the system sound going through JACK.. but their tool wont help with that i say | 02:20 |
| ollie__ | am I meant to use everything with jack? | 02:20 |
| holstein | ollie__: you dont have to. i dont | 02:20 |
| ollie__ | ah | 02:20 |
| ollie__ | well i dont know how to get my interface to work without jack | 02:20 |
| holstein | ollie__: you cant really yet, but you can do pulse to jack bridging | 02:21 |
| ollie__ | its saying jack server could not be started, sorry | 02:21 |
| ollie__ | every time its done that ive had to reboot to get it to work again | 02:21 |
| holstein | ollie__: i would just look at the messages and troubleshoot | 02:21 |
| ollie__ | is there another way? | 02:21 |
| holstein | it'll be permissions | 02:21 |
| holstein | ollie__: another way to what? | 02:21 |
| holstein | use your firewire device for all sound? not yet | 02:22 |
| holstein | the alsa firewire stuff is very new if available at all | 02:22 |
| ollie__ | i meant to get jack going again without rebooting | 02:22 |
| holstein | ollie__: i would read the messages and troubleshoot them | 02:22 |
| ollie__ | ok it appears to have frozen... reboot it is | 02:22 |
| holstein | ollie__: if it starts as ROOT, then its a permissions issue | 02:22 |
| holstein | ollie__: sudo killall jack or jackd | 02:22 |
| ollie__ | it was starting earlier as a normal user | 02:23 |
| holstein | or ps aux | grep jack | 02:23 |
| ollie__ | it worked momentarily | 02:23 |
| ollie__ | once i set the audio device as jack in the gui | 02:23 |
| holstein | ollie__: if its only starting for a blip, that doesnt count | 02:23 |
| ollie__ | i was playing music | 02:23 |
| holstein | ollie__: all im saying is if it runs as root, you can stop configuring the system | 02:23 |
| ollie__ | ok, well it runs | 02:24 |
| holstein | ollie__: you can relax the jack settings too... even more than i suggested | 02:24 |
| holstein | 2048/2 | 02:24 |
| ollie__ | Is jack for audio applications like ardour, or for everything? | 02:25 |
| ollie__ | At the moment I just want to get basic sound output through my interface | 02:25 |
| holstein | ollie__: JACK is open, so *anything* can be written with JACK support | 02:25 |
| holstein | jack connects any software and hardware that has jack support | 02:25 |
| holstein | ollie__: i just take a cable from the output of my internal sound card, and plug into the inputs on my device | 02:26 |
| ollie__ | is that ffado thing the driver for firewire devices? | 02:26 |
| holstein | ollie__: ffado is the firewire driver | 02:26 |
| holstein | i would just ask [lsd] in #opensourcemusicians | 02:27 |
| holstein | he as that device and uses it all the time | 02:27 |
| ollie__ | What would that do? I want to use the interface as my sound card | 02:27 |
| ollie__ | ah okay | 02:27 |
| ollie__ | thanks a lot for the help | 02:27 |
| holstein | ollie__: you can either use the pulse to jack bridge, or just use a jack aware player like audacious | 02:28 |
| holstein | or just take a cable and analog jack the internal sound care runnning pulse to the firewire interface | 02:28 |
| ollie__ | How do I use the pulse to jack bridge? | 02:31 |
| holstein | ollie__: AFAIK, its installed by default..i would just pop over and ask [lsd] about it | 02:31 |
| holstein | i dont use it | 02:31 |
| holstein | i just use audacious, or the cable | 02:31 |
| ollie__ | I've sent lsd a message, just waiting on a response | 02:32 |
| holstein | you have? | 02:33 |
| holstein | i would just message him in the channel.. but do what you like | 02:34 |
| ollie__ | i.imgur.com/cIZHN.jpg I've got my music playing, this time with realtime unticked, and it seems to be working better. Pic shows how I have it setup in the DE's sound settings | 02:34 |
| holstein | i typically dont send PM's without asking first | 02:34 |
| holstein | ollie__: if you have no lowlatency or RT kernel, theres no reason to check that box | 02:34 |
| holstein | i would leave it unticked, and just see if you can keep it running | 02:34 |
| ollie__ | How do I get rid of the gui without killing jack? | 02:34 |
| holstein | relax the settings to 2048/2 or whatever | 02:34 |
| holstein | ollie__: you can start jack from the command line, but then you dont have the connections | 02:35 |
| holstein | you can click the icon in the tray and it will minimize | 02:35 |
| holstein | there are settings about how you would likt it to minimize | 02:35 |
| ollie__ | ah, i see, cool | 02:37 |
| ollie__ | So I guess I should just set it to autostart | 02:37 |
| holstein | ollie__: i dont | 02:37 |
| holstein | ollie__: i like to see if start each time, and i have different profiles | 02:37 |
| holstein | try i though... see what you like | 02:37 |
| ollie__ | do you have sound from your interface without jack running? | 02:38 |
| ollie__ | because of your cable? | 02:38 |
| holstein | ollie__: sure | 02:38 |
| holstein | ollie__: i also have a console though that my audio is going through | 02:38 |
| ollie__ | Yeah thats why i'd want to autostart, as I need it on to get any sound | 02:39 |
| Stuzz | afternoon | 02:39 |
| ollie__ | hey | 02:39 |
| Stuzz | sup? | 02:40 |
| holstein | ollie__: try it... i dont | 02:40 |
| holstein | ollie__: you get sound through the device when JACK is not running | 02:40 |
| holstein | there should be a mix knob... a "live" side and a "computer" side | 02:40 |
| holstein | something like that | 02:40 |
| holstein | you can just use the preamps and the mixer as a PA with the unit unplugged from a computer | 02:41 |
| ollie__ | I suppose that could work | 02:42 |
| ollie__ | I like to route separate things to separate outputs though | 02:42 |
| holstein | ollie__: it does.. its how you "monitor" before things get tracked | 02:42 |
| ollie__ | one is my headphones, one is speakers | 02:42 |
| holstein | ollie__: route what you want where you want | 02:42 |
| holstein | im just saying what works for me... | 02:42 |
| ollie__ | sure | 02:42 |

| fruitflies | hi all, got an old ibookg3 that can run linux... is there a use for this as an audio tool, perhaps a really minimal midi sequencer?? tks. | 18:59 |
