Run configure again without --enable-capabilities. . but alsa is there and gives sound, no problems there. how to solve this? regards alex

[linux-audio-user] Jack and SHM

by Christophe Vescovi

Since there has been a lot of post concerning jack usage and optimisation recently it has remind me a problem I got that I never been able to understand. I have never been able to run jackstart with -R option when compiling jack with Sys V shm support. jackd -R as root work with SysV shm but if I want to use jackstart I have to use POSIX shm. The error message I am getting with SysV shm is the classical "cannot lock down memory for RT thread (Cannot allocate memory)". I am running a Mandrake 9.2 multimedia kernel (2.4.22, low latency, preemption and capability patches). Since most of jack users seem to use SysV shm I don't understand why I cannot (I am the only exception ....) Christophe

[linux-audio-user] alsa mixer apps

by Florian Schmidt

Hi, i heard on the #alsa irc channel, that some graphical mixer apps don't treat the alsa mixer [ctl] devices not right. For example on a cs46xx alsamixergui does not allow toggling capture on the "Capture" channel. This would be required and is no problem with alsamixergui. I wonder if other mixers have problems like this. This can be confusing like Hell to newbies.. -- http://www.soundclick.com/bands/9/florianschmidt.htm http://www.arted.biz/mista.tapas

[linux-audio-user] [ANN] Visecas 0.3.5

by Jan Weil

Announcing Visecas version 0.3.5. This is an interim release which fixes several serious bugs. Hacking Gtk::Fileselection from Ruby on a Debian system (which currently comes with a patched GtkFileselection) turned out to be a very bad idea regarding portability. New screenshots can be found on the web. Thanks to all those who reported their problems with version 0.3.1. Visecas is a graphical user interface (GTK+) for Ecasound [http://eca.cx/ecasound], a software package written by Kai Vehmanen which is designed for multitrack audio processing. It aims to provide full access to all Ecasound's object by preserving Ecasound's semantic (which means you do not edit tracks and regions but chains and audio objects). Please visit Visecas' webpage at http://visecas.sourceforge.net This release fixes: * broken audio objects' dialog * malformed preferences file crashes * silly behaviour with open/save as * crash once one of several chainsetups was closed * timeout problem (hopefully) * minor bugs Jan

Re: [linux-audio-user] Audio 3-D Demo --- Any Interest in Software?

by davidrclark＠earthlink.net

Hi Andreas, Thanks for your query, but I was unable to send email to your location from mine due to email restrictions on your end --- so I'm hoping you'll see this. Please let me know if you do. I hope it's OK to reply through the mailing list because I don't have any other way of contacting you. (BTW: Do other LAU people have the problem wherein they are contacted by a reader only to find that they cannot respond? What should we do in this situation? Is use of this list OK?) I'm developing this software as a research product into computational acoustics. I haven't decided what type of licenses to offer, but I'm leaning towards GPL or similar. Regards, Dave. Replying to: >Hello David, > >is that software available under an Open Source license or is it a >commercial product ? > >Cheers, >Andreas
