[linux-audio-user] good article on setting PCI latency and such

by Vincent Touquet

Hi, Just wanted to plug the following article: http://www-106.ibm.com/developerworks/linux/library/l-hw2/ Could be interesting if your soundcard is not getting enough PCI bus cycles and it is causing buffering problems. Another way to improve your low latency system. regards, v

[linux-audio-user] noteedit fails unless run as root

by Mikhail Ramendik

Hello! Previously, noteedit worked all right in my system, run as user. It worked with fluidsynth (which was run as root) via alsa. Now, it no longer starts as user. Instead it outputs a window that says: === An internal error happened somewhere. The message is: "correctReadTrillsSlursAndDynamics: internal error" Error Code is: 5 The program must be interrupted. === As root, it still starts and works. I have tried rebuilding noteedit; this did not solve the problem. The change in the system was that I have built and installed jack, ladspa and rosegarden. However, jackd is NOT running; nor is rosegarden. Of course, it's possible to run noteedit as root - seems like I'll have to do it with rosegarden anyway. But this is not something I'd prefer to do. Perhaps there is a cleaner way of fixing this? Thanks in advance for any answers! Yours, Mikhail Ramendik

[linux-audio-user] jack+fluidsynth: no sound

by Mikhail Ramendik

Hello! Sorry for the previous letter. The problem was fixed by pointing jackd to the device hw:0 . Now it does not crash - but nor does it output any sound! I run all of the following as root, in this order, from different terminal windows: jackd -d alsa -d hw:0 fluidsynth --verbose -a jack YamahaGrand_Adcock.SF2 noteedit I use NoteEdit because I have already tested it with fluidsynth (but without jack). The --verbose option for fluidsynth was added to diagnose the problem. So, I play something on noteedit - with all the default settings, in the same way as before (with alsa, when it worked). And I see noteon and noteoff lines in fluidsynth. But no sound is output! Tried aplay to the device hw:0 for a test. It works fine. So, the problem seems to be with either jack, or fluidsynth jack support. Thanks in advance for any tips on fixing this! Yours, Mikhail Ramendik

[linux-audio-user] Jack crashes

by Mikhail Ramendik

Hello! I am trying to use jack 0.70.4. The reason for the old version is simple - Rosegarden 4 0.9.1 fails to build with 0.72.4. /tmp/jack is symlinked to /mnt/ramfs. I start "jack -d alsa" from a root terminal window. It starts successfully (but with a warning about the "plug" layer). And it runs, although it reports xruns every time I move a window. This lasts while no clients are connected to jack. Now I start "fluidsynth -a jack" from another root terminal window. (No further parameters, and I have not attempted to get any actual sound as yet). It connects successfully. But very soon the following happens in the window that now runs jackd: === could not complete playback of 1024 frames cycle execution failure, exiting telling signal thread that the engine is done jack main caught signal 1 === With this, jackd exits. The same happens if rosegarden is used as the client, instead of fluidsynth. What should I do to fix this problem? Thanks in advance for any answers! Yours, Mikhail Ramendik

[linux-audio-user] Building a DAW - couple of questions

by Greg Reddin

Hey folks, I'm considering building a Linux DAW and have a few questions. First of all I have a Delta 1010LT soundcard. Does anyone have experience with using that card on Linux? Any caveats I should know about? Secondly, I think I've narrowed down my mobo/CPU combination and wonder if there's anything to watch out for there. Here it is: CPU: AMD Athlon XP 2400 Thoroughbred 2.0 Ghz 266Mhz FSB Mobo: Asus A7N8X Deluxe NVIDIA nForce2 SPP, nForce2 MCP-T chipsets Also, related to hardware, there seems to be a myriad of hard disk choices out there. The mobo seems to have built in support for standard ATA IDE and SATA. I haven't read the manual yet to find out the details, but I'm thinking about going the older ATA100, 7200RPM route since the drives are about half the price. Am I shooting myself in the foot by doing this? Should I buy a PCI IDE controller or is it possible to get reasonable results from the onboard controller? What are some drives you have had success (or failure) with? Finally, I would like to be able to record in remote locations without having to bring along a monitor, keyboard, mouse, etc. I was thinking about using my laptop to open a remote X session on the main box. Is that a practical scenario or would that drain too many resources on the main box to be productive? This is mainly an experimental project. I don't need this box for everyday professional use or anything. I'm just trying to build a Linux box on a shoestring and hopefully get it to work with the audio stuff. I'm really trying to keep costs down to around $400 US -- pipe dream maybe, but we'll see. Thanks, Greg __________________________________ Do you Yahoo!? The New Yahoo! Search - Faster. Easier.

Gnu/Linux has evolved so much, but it still can give you pains. My experience has also passed through times of trouble, but recently I've been dealing with it almost in perfection, since installing and updating the planet-ccrma packages at http://www-ccrma.stanford.edu/planetccrma/software/ This is RedHat based, so it would force you to change distro!!! It is apt based so most installs and update are automatic and in fact a breeze. If you want to try it out, I think it's one of the best sites around... Let me know if it works out! Cheers, Carlos

[linux-audio-user] ANN: Initial public release of the Linux version of Soundmesh -- an Internet2 audio streaming software

by Ivica Bukvic

Hi all, Announcing immediate availability of Soundmesh Internet2 audio streaming software. 1. What is Soundmesh Soundmesh is a result of a collaborative work with Mara Helmuth. It originally started as an "Internet Sound Exchange" Internet2 project and has since grown to become a full-fledged audio streaming front-end. The sole purpose of this app is to provide a mechanism for streaming multiple CD-quality (or better) audio soundfiles via fast Internet2 connection, utilizing hacked version of the RTcmix v.3.1.0. Hence, Soundmesh provides for a unique "jamming" tool via Internet for a larger groups of participants. 2. Obtaining Soundmesh Soundmesh is currently only available in a source form and is downloadable from my website. It's download is broken into 2 parts: the soundmesh front-end (~530KB)and the hacked full version of the RTcmix3.1.0 (8.2MB). They can be obtained using the following direct URL's: http://meowing.ccm.uc.edu/~ico/soundmesh/soundmesh-latest.tar.gz (~530KB) http://meowing.ccm.uc.edu/~ico/soundmesh/rtcmix-soundmesh.tar.gz (8.2MB) Alternately, you can also find the download links on my website. Documentation is also available: http://meowing.ccm.uc.edu/~ico/soundmesh/Documentation.txt Screenshot: http://meowing.ccm.uc.edu/~ico/soundmesh/Screenshot.jpg 3. Current Limitations *Soundmesh obviously does not currently support modular numbers of incoming and outgoing streams. This is something that is planned for a future release. *Perl (.pl) scorefiles are supported in soundmesh but do not work in RTcmix *Python RTcmix scorefiles are currently not supported and do not work with either soundmesh or this version of RTcmix *A number of playable streams before "gapping" occurs varies depending on the quality of a stream and the internet connection. Considering that this is an Internet2 project, chances are your modem connection will simply not work [well or at all]. *Sound played via network is not heard locally (should be a quick fix). *Connections are not secure. 4.

[linux-audio-user] Really basic /dev/dsp question

by Ken Goudsward

I am trying to set up a sound card under RedHat9 Kudzu detected it as a Creative Vibra 16x PnP (CT4170) So that is good but my apps (primarily XMMS) are trying to use /dev/dsp I suppose I need to make /dev/dsp into a symlink to the new device, but How do I find which /dev, if any, is setup as the new card? Or is there something else I need to do? Thanks, Ken Goudsward

[linux-audio-user] recovering tracks after hdd failure.

by Patrick Shirkey

I was recording a particularly roaring jam last night and my HDD overheated (I think). Why does it always happen when you are doing your best work? Anyway I have an extreemely large file which I cannot access with any of the players I have. Does anyone know how I can check the file to see if there is any useful info in it and recover whatever was recorded? I was using arecord so I assume that at least some of it was written to disk. I'm thinking I need to scan the file for the ggod info then cut it up with some thing that cuts files into bits and discard the junk then put it back together or just put the parts into seperate files. -- Patrick Shirkey - Boost Hardware Ltd. Http://www.boosthardware.com Http://www.djcj.org - The Linux Audio Users guide ======================================== Being on stage with the band in front of crowds shouting, "Get off! No! We want normal music!", I think that was more like acting than anything I've ever done. Goldie, 8 Nov, 2002 The Scotsman
