2.6.13.1-rt6, rlimits-patched pam and configured thus:
# in /etc/security/limits.conf
* - rt_priority 0
* - nice 0
@audio - rt_priority 50
@audio - nice -10
jack starts happily with realtime enabled, and the xruns are very few.
But no jack application will start, they all give this error:
jack_create_thread: error -1 switching current thread to rt for
inheritance: Unknown error 4294967295
It's like the ol' jack is root apps can't connect days, but I thought
rtlimits was supposed to make it possible for a user to get rt_priority.
Am I missing something?
Ah! It came to me just now - I set the priority field in qjackctl to 0
instead of 1 (where it was) and now jack apps can start. Heads up there.
Maybe applications need a way to recognize what rt_priority level to ask
for based on what jack is running at? On a tangent, how exactly does
that work? Is rt_priority=0 sufficiently prioritized? (because it is the
only thing running realtime)

Did you find anything?
I just started browsing
http://www.opendx.org
which should be open source. It is a modular visualization
system. Don't know if it helps but the gallery looks advanced.
I have a problem in checking out the CVS, though.

Hi!
I wonder if someone could provide me with the right hint, for I feel it is
not much to get me where I want.
I have an old suse system (gcc3.2 glibc 2.2.5), now I wanted to install a
newer gcc (3.4.3). It compiled fine and I can compile other programs with it.
Yet there is - apparently - some configuration problem. For if I start
linuxsampler or ecasound compiled with new gcc it says, it has a problem with
libgcc_s.so.1. It can't find some symbol VERSION_3_3 or something to that
effect. I tried ldd on those programs and it told me that they contain both
libgcc_s.so.1 from /lib and /usr/local/gcc343/lib. What am I doing wrong. For
I know this can work fine.
I recompiled my libstdc++ (from the 3.4.3 package) with my already installed
compiler to prevent it from including the old libgcc_s, but no effect.
What can I do? Should I put the new library-paths at a specific point in my
/etc/ld.so.conf? Set some special environment variable?
Any help is GREATLY APPRECIATED!
Kindest regards
Julien

Any help would be appreciated.
Does anyone know of a tool especially useful for visualizing room
impulse response measurements? Magnitude responses, waterfall plots and
such.
I'd prefer something more efficient and quicker to work with than octave
and gnuplot.

Full-duplex I/O with a minimal number of intervening buffers required (i.e.
very low throughput latency), preferably accessed through a callback
interface like JACK's. Last time I tried this it was quite complicated.
Maybe this has gotten easier in the last 2 years, but the docs don't seem to
be any different.

First release.
Sorry for the clanlib dependency, but it's what I could do quickly.
You'll possibly need to point the makefile in the right place. A
build system will appear some day.

How about a nicer interface to do synchronized I/O ? Currently the docs say,
in effect: "this is really hard .. just use JACK". I like JACK but there are
someinstances where it is not needed.

Hi,
I am an ALSA developer and I was wondering if there are any feature
requests that people who use this list would have.
I currently have a lot on my TODO list, but there is probably only one
feature on that list that might help you and that is dB level readouts
in alsamixer.
Currently, alsamixer uses a 0-100% readout, and on some sound cards 100%
is the 0dB level, and on others the 0dB level is around 80%.
This makes setting the capture levels rather difficult to get right in
Ardour. Most people would want the alsamixer capture volume controls to
all be set to 0dB and then let Ardour do any volume control.
Any other suggestions?

Dear linux-audio list!
(sorry for cross-posting)
PDradio is a self-regulating internet radio station for PD (Pure Data) related art (and is of course build with PD ;).
Upload your PD-related music, vote for songs, listen to the automatic radio moderator ...
The link: http://pdradio.iem.at
Please feel free to upload your music and participate!
We hope you have fun with it,

PDradio:
PD Webradio is a self-regulating internet radio station for the PD-community.
Registered users can upload PD-related music and share them with the community.
Because we didn't want to compile the radio program all the time we build an automatic radio DJ.
All user can vote for a song they would like to hear and the DJ will generate a playlist according to all votes.
Additionally there is an automatic radio moderator, who speaks a little bit about the songs (metadata which can be uploaded together with the music) and maybe is joking somtimes ...
PD-webradio is running on a Linux Server with Zope/Plone.
The audio streaming, speech synthesis, radio-moderator, DJ, ... is implemented in PD and Python for the communication to plone.
If you want to listen to the PDradio, vote for songs or you have music related to PD and want to share it - follow the link:
