Hi all, I am trying to record audio from my STM webcam the driver for it's sound card's driver is loaded automatically as snd-usb-audio. But When I try to record through sound recorder, it did't record anything. On seeing at the catc traces I came to know that the sound recorder even don't set the streaming alternates. Any suggestions?

[linux-audio-dev] Sound processing plugins' crashes

by Stefano D'Angelo

Hi, maybe it's just another of my dumb questions, however I would like to know whether it is happened to you that a sound processing plugin (LADSPA, LV2, VST, etc.) crashed (segm. faults, etc.). In such case, can you estimate how often does it happen that such plugins are misprogrammed? Thanks in advance, Stefano

When I wrote the above quoted sentence I did not imagine the (disproportionate) consequences this would have, and more importantly never intended to imply that a moderator was here to control if what was said on the list was right or wrong thinking. Although I do think that as a moderator and administrator myself I need to make sure a certain ethic is respected, the best way to deal with the original problematic message was just to ignore it, since the replies only caused a flame war. Concerning the need to decrease the work load of moderating the list, I propose another approach : As discussed previously on the list, we will certainly move to linuxaudio.org. Let's use this opportunity to tune mailman to our needs. There are not so much actual message that fall into the 'in-need-of-moderation' category. There are two actually : non-member messages and HTML messages. The biggest part of the job is to filter spam. My idea is to find a way to tweak (or apply an existing patch to) mailman so that messages marked as spam get discarded automatically, and also to be able to feed spamassassin with new spam samples directly from the moderation page. If you are willing to help, if you know of an existing solution or if you happen to have ideas concerning this, please, drop me an email. It is as of this momment the best way to help, and is the first step towards making moderation faster for every one. Again accept all my appologies. __________________ Marc-Olivier Barre, Markinoko.

I have loaded 64studio onto my only new SATA drive and now cannot boot at all ( black screen cursor only) Anyone any idea how I goot the machine? Or do I need to reinstall it all again.

Re: [linux-audio-dev] JACK data transfers

by danni

On a side note there is a discussion on the freebob list of whether to add a control api to Jack or just for freebob.

[linux-audio-dev] Sound processing objects architecture, is it possible?

by Stefano D'Angelo

Hi all, I'm quite new to sound-related programming, but however I have an idea which could interest some of you, but I don't know if it's possible to develop such thing. What I'd like to work on is a sound processing architecture (LADSPA, VST, DSSI, etc.) wrapper, which hides the details of a particular implementation to audio program developers. The whole thing could be made of a library to be used directly by audio developers in their programs, one or more configuration files used to retrieve directories in which plugins are placed and other stuff, and modules which contain implementation details for each processing architecture. The library could also contain some code to "trap" particular kinds of functions (for example Xlib functions to embed plugin GUIs inside programs). I think that the advantage of all of these stuff is to enable programs to use any kind of processing object (they could not only be loadable modules, but also text files or whatever), to collect "information" on how to implement a certain processing object type just in one place, and, last but not least, to ease creation of new standards and comparison of existing ones. What do you think about it? Sincerely, Stefano D'Angelo

[linux-audio-dev] a new patent for us to challenge

by Paul Davis

http://www.freshpatents.com/Low-latency-real-time-audio-streaming-dt2006040… in which Microsoft patents designs partially implemented by OSS 10 years ago and fully implemented by ALSA 5 years ago. Wrapping this up in windows API nonsense obscures the basic fact this design is not innovative in any way unless compared only to existing Windows audio driver architectures.

(He also said that he hadn't heard of LV2 before, so maybe he hasn't heard about ladspa either. :-) So if someone request ladspa, he might do that as well...)
