xruns with Rosegarden
by Tomasz Grzelak

Rate this Message:
Hello!
I'm writing to the mailing list about xruns because I get them ONLY when I try to use Rosegarden. My OS is: Debian (unstable) with kernel 2.6.24.7 + real time patches (-rt17) applied; software raid1 is used for all partitions. Hardware is AMD64 x2 6400+, 4 GB RAM, and Edirol FA-66 as the sound unit. I usually start QSynth (witch four engines), ZynAddSubFX, Hydrogen, Muse, Ardour, and JACK in the following way: jackd -R -P70 -t2000 -dfreebob -dhw:0 -r48000 -p128 -n3 -D Then I have no issues, I can work for several hours without an xrun. But when I try to use Rosegarden instead of Muse, I start getting xruns, more less one per a minute. It happens to hear a click/crackle then (not at every xrun), and additionally Rosegarden somehow looses its synchronization (or BPM measurement, I don't know how to call it), and starts playing noticeably slower - for example, Hydrogen starts playing a beat at 57th bar while Rosegarden reaches a 50th bar then. This synchronization loss does not happen at every xrun neither, just sometimes, but often enough to make Rosegarden unusable for me. I have followed instructions/suggestions about real time kernel preparation, mainly at: http://tapas.affenbande.org/wordpress/?page_id=40 My interrupts are: daemon:~/bin# cat /proc/interrupts CPU0 CPU1 0: 149 27 IO-APIC-edge timer 1: 0 3301 IO-APIC-edge i8042 4: 0 1 IO-APIC-edge 8: 4387 4605172 IO-APIC-edge rtc 9: 0 0 IO-APIC-fasteoi acpi 16: 339745 9307 IO-APIC-fasteoi nvidia 19: 3979385 78 IO-APIC-fasteoi ohci1394 20: 67599 2670 IO-APIC-fasteoi sata_nv, HDA Intel 21: 117173 2744 IO-APIC-fasteoi sata_nv 22: 0 29 IO-APIC-fasteoi ehci_hcd:usb2 23: 1 64256 IO-APIC-fasteoi ohci_hcd:usb1, sata_nv 505: 686520 1715 PCI-MSI-edge eth0 NMI: 0 0 Non-maskable interrupts LOC: 4103774 4101798 Local timer interrupts RES: 7526734 7904732 Rescheduling interrupts CAL: 797 855 function call interrupts TLB: 3268 4503 TLB shootdowns TRM: 0 0 Thermal event interrupts THR: 0 0 Threshold APIC interrupts SPU: 0 0 Spurious interrupts ERR: 0 I also set the FIFO sch., and high prio to the IRQ-8 & IRQ-19 processes: chrt -f -p 98 `pidof IRQ-8` chrt -f -p 82 `pidof IRQ-19` echo 8192 > /proc/sys/dev/rtc/max-user-freq Next I start JACK, and other audio software. In the htop processes look like this then: http://picasaweb.google.com/tgrzelak/Audio/photo#5235864409871263538 [you can see there are quite many xruns reported] Now... what I have tried before asking you for help: 1. Starting JACK with larger buffer: jackd -R -P70 -t2000 -dfreebob -dhw:0 -r48000 -p512 -n3 -D 2. Having used the 'nv' driver instead of the binary 'nvidia' one (I have GeForce 8800GTX if that matters), and some light window manager - Window Maker. 3. Rosegarden 1.7.1 compiled from source (currently I have 1.7.0 in Debian repositories). 4. JACK 0.112.1 compiled from svn repositories. 5. JACK 0.112.1 with FFADO backend instead of FreeBoB. No matter what I have tried, the situation looked the same every time - not possible to work with Rosegarden, no problems with Muse. I must say I'm running out of ideas. I don't know what to check/try more, especially xruns happen ONLY while using Rosegarden! Rosegarden seems to be a great environment with lots of useful features, and convenient usage, and I'd like to have it as the main MIDI seq software, but somehow it is unusable for me. I'd be thankful for help with this issue.

I've just make another test - I have run JACK & Rosegarden only, without any other audio applications. Look at what I've got after 10 minutes of doing nothing (Rosegarden was only run, and in the meantime I was reading mails): http://picasaweb.google.com/tgrzelak/Audio/photo#5236609217996444898 almost 30 xruns in ten minutes of doing nothing, only with Jack & Rosegarden running :/ In comparison, when I work simultaneously with many audio applications (Muse+Qsynth+ZynAddSubFX+Hydrogen+Ardour) I usually get only 2 or 3 xruns when starting synthesizers programs, and then can work as long as I want without any problems (no xruns). I hope the Rosegarden issue will be fixed soon. Cheers!

I do care, but I can't do anything to help you. You run Debian Unstable, which is not a distro but a collection of proposed packages that might make it into a distro. You run your own kernel. You run hardware of which I have no first-hand knowledge (the firewire audio dongle, and even your basic computer) and you throw RAID into the mix. It would be hard enough for me to even try to suggest a solution if we had more in common, but as things stand now, we have practically nothing in common at all. Rosegarden doesn't have this problem on my computer. I run Ubuntu Studio with Kubuntu packages on top of it, on a 3.2 GHz Pentium D with 2 GB of RAM. I have an Audiophile 2496, a Sound Blaster Live! 5.1, and built-in Intel HDA, with the Audiophile as my JACK card. I run the proprietary NVIDIA drivers too, because I can't get my widescreen display to work properly without them. We have totally different environments, and me saying everything works here is just as useless to you as you saying it doesn't work there is useless to me. We have very little common ground for meaningful comparison here, and there's little I can do except feel sorry for your misery. I would suggest that since you seem to like pure Debian over Ubuntu, you might give 64 Studio a try. I haven't used 64 Studio, but I've read a lot of their pages, and it seems to be a very good distro for audio work. I can personally vouch for Ubuntu Studio being a very good distro for audio work as well. I would furthermore suggest that Debian Unstable is a really bad choice for an audio platform, because it's too unstable, and too unpredictable. Packages are often buggy, and they interact with each other in complex ways, so that somebody who upgraded on Monday and Thursday might wind up with a buggy system that someone who upgraded on Tuesday and Thursday might not. I concede that you have everything else working so well that your environment is probably OK this time, but just in terms of a long-term strategy, trying to do this kind of thing with Debian Unstable is a lot of work for nothing. I did the same thing for years myself, and I'm speaking from experience. Switching to Ubuntu Studio was a great move for me, because I now have the luxury of not knowing much of anything about how to put together a JACK-friendly setup. Someone else keeps up with all the changes in this and that, and it just works. I love it! In any case, Chris might still have some insight to offer here. I've said all there is any point in my saying, and I wish you the best of luck with your trouble. -- D.

So unfortunately it's not a problem as you suggested. It must be something else. Problems with Rosegarden made me experiment with other versions of different software, and that's why I started using the 0.112.1 version. Besides when I use Muse both version of JACK work fine with audio applications on my system.

you understood me wrong, sorry, it's probably my "personal" version of English ;) I meant I was happy to see a response for this problem, it was not an accusation in any way! Sorry once again, I was just satisfied it interested developers, and hoped to be investigated more.
like I wrote above - misunderstanding :)
agree
I suppose so. It's a very popular and good environment, and that's why I wanted to give it a try, and still want, but I'm running out of ideas slowly, because somehow only Rosegarden is unusable on my system.
I agree too, but I'm also willing to give any more needed information about my system to diagnose the problem. I understand it's very hard (I'm not a computer/Linux newbie), but at the moment I just don't know what more can have influence for such behaviour. I have been thinking of RAID for many times, but in that case why do other JACK apllications work fine? If they all were not working, it would be easy to say "Debian unstable with RAID is not good for this stuff". But... there's always this "BUT" :) ... everything I use works fine besides Rosegarden. So it makes me totally confused :/
I must say I have thought of some other audio distro, but ("BUT" again ;) ) I use my Debian not only for audio stuff, but lots of other tasks, and have there many important data (including my music, and work); that's why I need this RAID too. What's more, I have used Debian for many years, and there's no other OS/Distro that I feel so comfortable with. Maybe I'll try to install 64studio... to see if there's any difference. Do you think it would wise to install it on some USB disk/pendrive? I'm just not very happy when thinking of repartitioning my drives... Thanks for your help!

Hi Tomas,
I think the answer to your problem may be to dual boot between Debian unstable and either Studio 64 or Ubuntu Studio. Like you, I do a lot of things unrelated to audio (I teach 2 Linux classes at the local community college for network admin majors). I actually have a quad boot setup between OpenSuse, JAD (Jack Audio Distribution), Ubuntu Studio, and Windows. I do most of my audio work in JAD; sometimes Ubuntu Studio and all of my network administration stuff in OpenSuse. Windows is only there for the occasional app that I have to use for network administration that is Windows only. As others have said, running a proven stable Audio distro will give you the best audio results and you are a lot less likely to have to mess around with the kernel etc. to get things going Hope this helps.

I used Debian Sid for many years too, and was very skeptical about making the switch to Ubuntu. I finally did it after some series of incremental package upgrades completely broke audio to a point where nothing was working, and I had little to lose. It worked out well. I use (K)Ubuntu Studio for everything, and that's one of the pleasant things that sets it apart from earlier distros that tried to solve the problems with audio. It's not just for audio, but audio plus whatever else you would normally do, and it's Debian enough to keep me happy. > Maybe I'll try to install 64studio... to see if there's any difference. > Do you think it would wise to install it on some USB disk/pendrive? > I'm just not very happy when thinking of repartitioning my drives... They might have a live CD. Looks like they do: http://64studio.com/download I'd try the live CD first. See if that gets you anywhere. If not, then blame it all on Rosegarden and carry on. :) -- D.

I can leave Rosegarden (and only Rosegarden without any other JACK application running) doing nothing for several minutes, and when I return I can see several xruns more. On the other hand, I can run Muse doing nothing for an hour (with many other JACK applications), and then I don't get a particular xrun. I've made this kind of tests too. I've even tried to compose/play my music with some big software having compiled in the background on two CPU cores, from time to time rotating my compiz cube, and what's interesting - only one xrun occured during that quite long time os the stress. But I've noticed one interesting thing - it seems to get 3 or 4 times more xruns when a screensaver (OpenGL) activates in the meantime of doing nothing. But like I wrote before - I tried to run Rosegarden in WindowMaker (without any screensaver) on open source "nv" driver, and it didn't change anything about xruns. So no matter if I use the open "nv" or proprietary "nvidia" driver, it does not make any difference. > buffers to jack within a range of time. > possible reasons: > - rosegarden doesn't get enough cpu time > possible reason: it cannot accuire real-time-priority > so another process is stealing cpu time > (maybe just every minute) only one so important I can think of would the RAID daemon, but why do other apps work fine somehow?

No real contribution, but it sounds to me like your video and sound hardware might be sharing an interrupt.
