Re: help, my Jack doesn't work anymore
thanks a lot for your reply. i tried your solution, but nothing is changed. when i start qjackctl it seems freezed. I can get control of it just only killing the jackd process. and if i start it again, it launchs jackd, but it's freezed (until killng jackd). I'm thinking on a new install of ubuntustudio, but i don't like this solution :-( regards Beppe 2012/9/16 Ralf Mardorf ralf.mard...@alice-dsl.net On Sun, 2012-09-16 at 10:19 +0200, Beppe Zupa wrote: hi friends, i don't know what's happens on my notebook, but from a day to other the Jack on my ubuntustudio 12.04 has stopped to work. i attached the log at this email, in hope someone could help me. it seems that another app is locking audio resource, but i don't know how to find this app to kill.

Horrific jackd xrun behaviour after upgrade from US 10.04 to 12.04
Hi, the subject says it all ... I had an install of 10.04 that worked. Only issue seemed to be instability when recording while a USB drive is connected. So, considering that perhaps this is a sign to replace a mainboard with broken onboard USB (used a PCI add-on card, which might have worsened the interrupt situation), I did replace it and the machine worked fine during a session. Now with the fully replaced hardware (Asus AM3 board with 780G chipset, Athlon || X3 460, 8 Gig of Kingston DDR3 ValueRAM, 250 G Seagate SATA boot, 2 WD EADS on mdraid for recordings and not to forget VIA firewire on PCI-E (same card as before)) and the update to ubuntu 12.04 (yes, should have tested the final hardware with 10.04 first, eh?), the performance is hindered by jackd not being able to keep steady without generating xruns at a some rate. Not really constant rate, though, also its behaviour depends on client connections (even when just connecting meterbridge, this seems to help triggering xruns a lot). A very interesting fact is that using 3x512 periods (or bigger) is less stable even than going down to 3x32! With big periods, I get xruns right away, while with the low setting, I was able to get an hour of recording done, but that ended prematurely -- I _guess_ that this was because of some software glitch (like xrun handling) and not due to the bass player nudging the keyboard by chance. But I cannot be sure about that. Now, I do have the lowlatency kernel already installed, also fresh jack/ardour from kxstudio ... have rtirq setup updated by dpkg (firewire in there instead of ohci1394). What are the ubuntu studio folks' thoughts on this? Did you encounter _more_ stable jack with extremely low latencies? But since it is not really stable and glitch-free in any config, this interesting characteristic does not help. Oh, and it happens independent of cpufreq governor. I do use XFCE and the integrated radeon with open source driver. Any help on getting that setup stable again is appreciated ... or should I simply go back to 10.04 (and hand-install current ardour/jack, as I did before)? I figure that I shouldn't even need a lowlat kernel for getting basic 3x512 recording work! Alrighty then, Thomas. PS: Why upgrade at all? Well, I have always a spark of hope that some iteration of the GNU/Linux audio ecosystem will be really stable, without random crashes of Ardour, for example. But I guess one has to live with crashing multimedia apps ... not been that different during my days doing video with Ulead Media Studio on Windows (and the fact that version 5 was less usable than 2.5). signature.asc Description: PGP signature -- 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: R: Audio issues in 10.04
Short reply coming up. I would recommend looking for something that's probably called kxstudio-welcome or something similar in the repository. More specifically what you need is the kxstudio welcome script, which sets your system up properly automatically. I can also warmly recommend getting the full kxstudio distribution, it's great!

R: Re: R: Audio issues in 10.04
If I understand correctly, KXStudio is not a distro. You need to install a distro (Ubuntu Studio is a good option, but others might work, I don't know), and then activate the additional repositories in synaptic manager and from there, install the items that you want. You might start with Ubuntu Studio 12.04 (it has long-term support and lots of updates). Then from there, see what else you need. Personally, I like how KXStudio interfaces with Ubuntu Studio. Two very good projects, imo.. brian Messaggio originale Da: thomas-fo...@orgis.org Data: 17-set-2012 15.26 A: ubuntu-studio-users@lists.ubuntu.com Cc: brian.coll...@alice.itbrian.coll...@alice.it Ogg: Re: R: Audio issues in 10.04 Am Mon, 17 Sep 2012 14:12:40 +0200 (CEST) schrieb brian.coll...@alice.it brian.coll...@alice.it: Hello Thomas, I use KXStudio on top of UbuntuStudio, but the 12.04 version.

If I thought it was the upgrade from 10.04 to 12.04 that is the issue, I would try a 12.04 live cd and see how it works with the usb device. I typically use the live cd's as a tool to see hoe the hardware support is, which is, as I see it, the issue you have. I still use ubuntustuio 10.04 in my studio with a firewire device and it is rock solid. Tests of 12.04 and 12.10 only show improvment. i installed jack on my netbook running 12.04 and a generic kernel and JACK runs stable. if that were my system, i would also try the internal sound card for troubleshooting purposes. i think you'll find a scenario where with good quality, and well supported hardware JACK will run stable, and checking in with what version of ardour you are running and upgrading should fix any stability issues with it. i also have one odd tascam USB device that when running under ubuntu 10.04 actually has much worse performance with the realtime kernel. the best support for it is with a generic kernel from the ubuntu repos. ALSO, i use the kxstudio ppa's a lot, and quite like them, and the developer is great. i would not suggest using KXstudio to try and add support or increase the stability of a device that cannot be supported well, or has misconfigured interrupts. i would use KXstudio to add newer or different packages to ubuntu or ubuntustudio... not to magically repair an xrun issue... i assure you, in my test, JACK *is* quite stable, and setting up and configuring USB devices can challenging. -- next part -- A non-text attachment was scrubbed...
