[linux-audio-user] Why doesn't this link work?

by Marv Smoak

I guess it's a character flaw on my part but this is driving me nuts. Yesterday I spent a couple of hours trying to figure out why my system does not play an audio clip at the site below. The clip is from an NPR show, SoundMoney, and is of interest to my wife, a prof in the School of Business at Xavier University. Her machine, running that other OS, plays it; mine RH 8.0 from Planet CCRMA (vintage March 2003) plays Real streams with no problems; I use it every day. (note some long lines below may have "wrap"ed.) At the NPR SoundMoney site there is a link to http://www.reppe.com/ At that site (below the picture) we see: Rik's Latest on NPR's Sound Money 2/7/04 - Why Capitalism Rocks: Twix, Frisbees, and the Grateful Dead Listen the Listen link is to: http://www.soundmoney.org/play/audio2.php?media=/2004/02/07_soundmoney&star… When I click on it, my Konqueror browser asks what program to open it with. If I say Konqueror, the Konqueror displays the audio2.php file: <smil> <body> <seq> <audio src="rtsp://a754.v5559f.c5559.g.vr.akamaistream.net/ondemand/7/754/5559/v001/mpr…" clip-begin="00:00:53:24.0" clip-end="00:00:57:54.5"/> </seq> </body> </smil> Usually, Konqueror opens real streams with realplay with no problems. If I say open with realplay, realplay comes up and fails to play, complaining that "Some component is missing ..." After much searching on google and google groups, I think I've learned that the web site itself is failing to execute the .php file and not sending the stream. I also tried using Mozilla and wget with the same results. This is not an important problem for me, but it is bugging me to the point of distraction. Do any of you folks understand what's happening and why my wifes OS plays and mine won't?

I don't think this is a problem; you can usually turn off the GC during time-critical code, and in most cases, such code is in C anyway (handled via a foreign function interface), and at least in normal use, you're in control at that level. Besides, modern hardware is far faster than people seem to realize, and modern GC's don't spend much time on a sweep. Gad, now I'll have to go and run some tests...

Infact, I don't think there is a function for it, and its definitely needed. Shouldn't we try to convince the guile people to add that functionality? --

[linux-audio-user] is it likely that JACK get included in any of these distros? what about SC?

by micro.ispretty

hi am still making footprints as a linux user started using SC3 @ OSX but prefer using it @ promt mode linux the difficult part of linux is that you have to learn a lot before you run a program if it is not included in the distro the best way for me to learn is to run anyway and learn deeper gradually and a about to make my mind to just wait until things get prepared in the distro since ALSA became the default of Kernel 2.6.x is it likely that JACK will also get included in any of many distros? i will at least learn Planet or DeMuDi ? what about SClang? will i be waiting forever because there is some reason that things cannot be handled that way? __________________________________ Do you Yahoo!?

[linux-audio-user] ALSA compatible sequencers

by Mark Johnathan Greenaway

Are there any sequencers that support using ALSA for MIDI i.e. could control Hydrogen/alsamodularsynth/fluidsynth? Mark

RE: [linux-audio-user] RME DIGI 96/8 PAD or Marian Marc 2 Pro

by Reuben Martin

I use a 96/8 Pad. Works great with ALSA and Jack both. I try to keep this page up to date about RME96/8: http://alsa.opensrc.org/index.php?page=rme96 I can't speak for the Marian Marc 2 Pro. If you're up to it, I would recommend Gentoo over Red Hat + Planet CCRAM. It takes more work, but I get much better response from my machine with audio apps under gentoo. regards -Reuben -----Original Message----- From: Mirouf Linux [mailto:mirouflinuxaudio@yahoo.fr] Sent: Tuesday, February 10, 2004 3:33 PM To: linux-audio-user(a)music.columbia.edu Subject: [linux-audio-user] RME DIGI 96/8 PAD or Marian Marc 2 Pro Hi everybody, I've got choice between RME Digi 96/8 PAD and Marian Marc 2 Pro in order to put in a Linux Box runnig Red Hat 9 and Planet CCRAM. Somebody Told me the RME Digi 96/8 series have some problems with alsa settings, did anyone use it? Does it work well with/without Jack ? Did someone run a Marian Card with ALSA (no info on alsa-project home page), and specialy a Marc 2 Pro? Does it work? Thanks François Gueurce Yahoo!

Re: [linux-audio-user] Should I Bother Learning Csound?

I'd say its a supergreat combination where you get easy/clean programming with python, functional programming with the guile pd-external, sound processing power with SC3, and GUI with pd.

C are fine for making hardware drivers, c++ can be fine if you need OO to C, and java is horrible in all possible ways. My opinion. :) --
