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

[linux-audio-user] interrupt question

by Robert Epprecht

I have moved my soundcard to a new computer, and wanted to have it on a high priority interrupt. The mobo is ASUS P4P800. lspci tells me something like "pin A routed to IRQ 23" (or similar) I do not know anything about interrupt priority with these new irq's. Pointers, informations or help highly appreciated. Robert Epprecht

[linux-audio-user] ANN: Specimen Version 0.0.3 Released

by Pete Bessman

Guess what? ...*chirp*...*chirp*... Right, well... Specimen is midi controlled audio sampler for GNU/Linux systems, and this is a new release of it. I'm justifying this on the inclusion of velocity sensitivity, cuts, and proof-of-concept (read: crappy) pitch scaling. You can download the newest tarball, check out the new screenshot, and listen to the _fearsome_might_ of Specimen at www.gazuga.net. [pb]

Re: [linux-audio-user] Which kernel for low latency and kernel 2.6.1-mm# problems

by davidrclark＠earthlink.net

I've read some of these discussions and cannot offer much, except that I have been trying to use the SATA driver in "enhanced" mode with an ASUS board with Intel ICH5R chipset. This is impossible to do for very long. Eventually accessing the hard drives causes the machine to lock up. If the mouse is moved while a process that has extensive disk activity is running, erratic behaviour results, such as pasting of text into xterms. I've also observed that it is impossible to run e2fsck on a large drive without it halting. Hitting keys, especially Ctl-Alt-Del, will restart e2fsck, this must be done repeatedly (dozens of times for checking 3 PATA's and one SATA). What does this have to do with jack? I come down on the side of a very serious bug in the kernel, scheduler, something of that nature --- not jack or the SATA driver. I believe that other demanding drivers must be also having problems. Now I am running a P4/800 in APIC mode for 2.6.1 with low-latency selected. I have not tried jack yet (not that far along). I'm also running Slackware 9.1 (uses devfs). I think we'll all be very happy with this new kernel once this gets worked out. It has a lot of good features. I like the build process better, too, and gconfig. Dave.
