USB-audio card recommendation please
Hi, I'm sick of waiting for Presonus to getting around to supporting FFADO (I bought a Firebox - at the moment an expensive paperweight). Could some please recommend a USB-bus powered audio (audio/midi) interface that works flawlessly with Ubuntu Studio?

Re: Presonus
Hi, Great to hear that you're getting those kinds of results with your Firebox, are you using the freebob or ffado drivers? and on Ustudio 8.04 or 8.10? and what is your setup? I haven't really had a satisfactory result with my firebox so far and I've been waiting for the FFADO drivers to improve. Hopefully someone puts up a deb for Intrepid soon as it's a mystery to me how to compile it from source with all the unresolved dependencies etc...

Breakage on Ubuntu Studio
Has anyone had any luck getting Breakage working on Ubuntu Studio? The Breakage forums don't have much information... http://www.blackholeprojector.com/ -- Ubuntu-Studio-users mailing list Ubuntu-Studio-users@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-studio-users
Re: firebox, expensive paperweight
Hi Andrew, Recompiling drivers is a little out of the range of my technical skills. I'll wait. thanks heaps. I can follow simple instructions and make music. It's great that there's hope for the Firebox. peace Hamish -- Ubuntu-Studio-users mailing list Ubuntu-Studio-users@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-studio-users
firebox, expensive paperweight
I realised that my Zoom H4, that I use for radio journalism and field recordings can also be an audio interface. It doesn't work well on full-duplex, and there is the occasional (rare) x-run. But I'm stoked, at least now i can use all this great software.

Any clues?
So I've been able to make everything work, have now created a separate user login with as few extraneous applications as possible. If anyone has any clues what I should try next please let me know. Also there's a minor digital static with every hit of the midi keyboard, it's minor but annoying. Also I'm not sure at what level would be optimal to set the memlock percentage at. My setup again: Laptop with Hardy Kernel Linux 2.6.24-19-rt gnome 2.22.3 memory: 1011.0 MiB Processor: Intel(R) M processor 1.80GHz M-Audio Axiom 25 USB Midi keyboard Presonus Firebox Jack crashes after 2-5 minutes, and always with the same output in the messages window. the whole system suddenly becomes overloaded. Perhaps it's not even a problem with the Presonus Firebox/freebob?? Qjackctl's output upon crashing is: 10:56:55.455 Audio active patchbay scan... 10:56:55.457 first: ardour:click/out 1 -> system:playback_1 checked. 10:57:00.718 JACK connection graph change. 10:57:00.735 Shutdown notification. 10:57:00.758 Post-shutdown script... 10:57:00.759 killall jackd cannot complete execution of the processing graph (Resource temporarily unavailable) zombified - calling shutdown handler 10:57:00.858 Audio active patchbay scan... 10:57:01.189 Post-shutdown script terminated successfully. 10:57:02.747 ALSA connection graph change. 10:57:02.867 MIDI active patchbay scan... 10:57:02.869 ALSA connection change. 10:57:03.070 MIDI active patchbay scan... I can't fathom the bad luck i've had so far first with an M-Audio Quattro then shelling out for the Firebox and now it looks like i either need another soundcard, or a 64-bit laptop because hopefully when my musical ideas are realised i'll be able to tour and work as i travel if anyone has any idea how i can salvage my setup please let me know else it's months of wage-slavery till i can upgrade Hamish -- Ubuntu-Studio-users mailing list Ubuntu-Studio-users@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-studio-users
different startup scripts
Thanks Gustin, I'm not using flgrx because it's in failsafe, flgrx only starts up if I go into ubuntu normally. I'll try your suggestions. What would be the best way of enabling different startup scripts, either for a different session or a different user so I could specify a low-CPU 2d ubuntu for when i want to make music (after selecting the rt kernel on startup). The more automatic all this is the better.

trial and error
hi, I've been trying to get a fully working setup for linux audio for a really long time. Partly my delay was not having the right gear, I spent 6 months trying to get one soundcard that wasn't supported (though the list had said it was) working and then, with help I've been able to get some sound out of my system now with a Presonus Firebox. Still I have problems, partly I guess because I'm not a techie, but I've been stubborn enough to keep trying all this time. Anyway the point I'm at now is that I can boot up into the realtime kernel - I need to go into a failsafe gnome session as then flgrx doesn't start up (it's really greedy with processing power, but when I'm not making audio it is very useful and looks great), and compiz-switch only turns off the effects, it doesn't free up the processor. I open the Ubuntu Studio Controls and enable raw 1394. What percentage should I put the memory lock at? I run a little start up script > jackd -R -dfreebob because for some reason I can't start the Firebox/freebob with qjackctl. But after running the script I can start qjackctl and jack is already running. I then start up some applications, they all appear in the ALSA tab, nothing appears in the MIDI tab and sometimes the audio ports are visible in the Audio tab and sometimes not, it seems random. So sometimes I'm able to link the apps to my soundcard, and sometimes not. I've been able to do a few things, link my midi keyboard to a synth to jack rack and record it in Ardour. Record some guitar with a microphone. But the whole system is so unstable that it's almost unusable. Every 2-5 minutes the system will crash. Perhaps my whole system is not up to spec, i've got a laptop with 1 gb RAM, and 1.7ghz M processor, it's a few years old but it should still be kick-ass enough to run a stable system. It is 32-bit though and it sounds like others are running more stable systems on 64-bit computers. I'll get one when this laptop dies, but i hope that won't happen for years and years to come. Anyway I just want to make some sound. I've invested so much time and money so far. I really want to make music using these great open source apps and contribute by raising linux audio's profile in the process. What, if anything am I doing wrong and how can I have a fully stable system on this laptop? Is it even possible? Should I switch back to Windows until Presonus help out the FFADO people? Or until I can afford a new system... It seems I spend all my time messing around with things trying to make it work, making enough progress here and there to make it seem like I'm getting somewhere when I'm not really getting any music made. Anyway, I fully see the massive potential that linux audio has, far beyond the limitations of proprietary software, and respect to the people who are working on the applications. Any advice appreciated.
