Hi all, I've compiled and run; jack 0.99.0 qjackctl 0.2.12a fluidsynth 1.0.5 qsynth 0.2.2; & rosegarden 0.9.8 They all seem to run okay. I've messed around with qjackctl's settings and matched them to qsynth's to get a good balance of low latency and actually working. Everything seems fine, except when working with RG I occasionaly get requesters saying "JACK is losing sample frames". It doesn't happen all the time, it seems to happen more often when several windows are open (eg the notation editor and the main window). I think it's possibly just that my setup is a bit slow and I could live with the occasional click in playback without the requesters popping up all the time. Is there anyway to turn off RG reporting that JACK is losing sample frames? AND/OR Are there anymore ideas about helping JACK to not drop frames other than what I've read in this list and on other sites? (I'm running kernel2.6 under FC2 on a P3-500 based PC btw.) - Qjackctl Settings --- Audio=2 Chan=0 Dither=0 Driver=alsa Frames=16 HWMeter=false HWMon=false IgnoreHW=false InChannels=0 InDevice=\0 Interface=hw:0 Monitor=false NoMemLock=false OutChannels=0 OutDevice=\0 Periods=1 PortMax=128 Priority=0 Realtime=true SampleRate=44100 Server=jackd Shorts=true SoftMode=true StartDelay=2 Timeout=500 Verbose=false Wait=21333 WordLength=16 --- |

I've seen this with RG when using low latency settings. With your PC you might just have to run a bit looser. A few other ideas - What window manager? Are there xruns reported at the same time? Good luck, Mark |

Always with the upgrades. lol Thanks I though I had the latest source here already. Yeah I have the RLSM mod happening already. I think jack is getting the priveleges okay. It'd be nice to get down to making some music instead of configuring stuff all the time. I seem to spend all my time configuring. >.<' -- Bunny! |

But turning these things up and down doesn't seem to make the xruns & RG reports come any more or less often. I've tried setups that report latencies from 3.3 to several hundred lol. I'm running Gnome atm and I'm thinking that since it seems to happen more often during times when more windows are opened it may be an issue like that. That's why I'm thinking that I'd just like RG to shut up about it. I mean I can HEAR when JACK's dropping frames. It's funny when RG pops up a requester like that it causes JACK to drop more frames and RG to pop up another requestoer lol. -- Bunny! |

Open the RG source file gui/sequencemanager.cpp in a text editor. Look for the following lines (at lines 1013 onwards in RG 0.9.9): QString message = i18n("JACK Audio subsystem is losing sample frames."); boolShowingWarning = true; KMessageBox::information(0, message); boolShowingWarning = false; Comment out the third of these lines by adding "//" at the start: // KMessageBox::information(0, message); and remake Rosegarden. In current CVS (but not 0.9.9) there's a #define to control this in that source file, and it'll probably become a user-configurable option in future versions. Chris |

Thanks that'll shut it up so I can get some actual work done. Later I can work out if I can stop those audio blips. -- Bunny! |

Part of it has a lot to do with your hardware, I suspect. How many things you have vying for interrupts, how fast your computer is, how crappy your soundcard is. I get all kinds of sample frame period resolution latency frame foo foo bunny gibberish myself, and I'm on a 2.0 GHz box. > mean I can HEAR when JACK's dropping frames. It's funny when RG pops up a > requester like that it causes JACK to drop more frames and RG to pop up > another requestoer lol. Rich did that to encourage people to fix what was wrong with their setup. You said you have a 500 MHz box? That's what's wrong with your setup, probably. That, and you probably have a crappy soundcard. It seems to get good results with no troubles you need to hork up some bucks. Dunno, sour grapes again I guess. I'm probably being a bit too pessimistic. I managed to develop a positive attitude toward audio stuff, and I held onto that attitude for a good while, but then I got back to my MIDI and notation roots, and haven't been doing much with audio. It's just such an incredible pain in the ass getting anything useful to happen. It can be done, but I hate fooling with it, and I'm not doing so currently. So take what Mr. Happy here is saying with some measure of salt I guess. -- Michael McIntyre ---- Silvan <dmm...@us...> Linux fanatic, and certified Geek; registered Linux user #243621 http://www.geocities.com/Paris/Rue/5407/ http://rosegarden.sourceforge.net/tutorial/ |

Nah, just a low-latency kernel I'm using a 600 MHz Celeron on 256 mB RAM. It's good enough for most purpos= es.=20 Dropping softmode sounds worth experimenting with.

It's the Frames/Period and Periods/Buffer settings you want to play with. Periods/Buffer is usually a small value like 2 or 3, your soundcard will=20 probably be quite fussy about this and only like one particular value. =46rames/Period - I find between 256 and 1024 at 2 periods/buffer to work w= ell. cheers tim hall |

Chris made me turn it off. I get more xruns, but it got rid of the crackle pop stuff, and I usually don't get xruns when it matters.

I always seem to be 3 > years behind SotA. Me too. It's nicer than it used to be though. It used to be a $500 computer was a total waste of money, but I had to run a PII-233 for a couple of months, and it didn't kill me. $500 buys you plenty of machine these days. I gave up on SotA when I realized there were no games at the store I would want to play if someone gave them to me free. Games used to be my big reason for trying to stay on the edge, but at some point either I grew up or the games really started to suck. -- Michael McIntyre ---- Silvan <dmm...@us...> Linux fanatic, and certified Geek; registered Linux user #243621 http://www.geocities.com/Paris/Rue/5407/ http://rosegarden.sourceforge.net/tutorial/ |
