Well, the ALSA support shall be achieved sooner or later :) But it's true that there is still a significant gap between the product release and the support on Linux. Once people recognize the importance of Linux desktop, this gap will be decreaed, I guess. My biggest concern is the chaos like what has happend on USB audio/midi (or look at ACPI). I really hope such a theatrical confusion won't happen on fireware audio. The precised specification doesn't always lead to a good result :) Takashi

There was a thread about a project of "open > source" graphic card recently on lkml. I know about the project in question, as I participate in the discussion about it. an open design sound card would be even easier to design... an atmel microcontroller and a pair of ADC / DAC chips should be enough to desing something with a USB port. now for the firewire thing, I guess a xilinx chip can do it, and those are not that expensive either...

[linux-audio-dev] Novation ReMOTE, Speedio & XStation

by Nick Dowell

Hi, I noticed there has been some discussion as to whether novation usb midi and/or audio products will work with linux: http://www.music.columbia.edu/pipermail/linux-audio-user/2003-August/ 005765.html I can tell you that the audio side of all out usb products are usb class compliant, so they should work with the usb audio class drivers. If they don't, please let me know. The MIDI communication is not class compliant. It is a very simple protocol though, and should be easy to implement. If anyone wants information to write one we'd be more than happy to give it. Thanks.

[linux-audio-dev] Re: Tascam US428 Hangup

by Spencer Russell

I got the latest alsa-drivers from CVS, compiled and installed them, and it's still freezing up. I can have the modules loaded for as long as I like, but it's when I start jack that it seems to have problems. Most recently, I started qjackctl, it worked until I started Ardour, at which point qjackctl died. I killed and restarted jackd, and as soon as I started jackd my computer froze. Every time it freezes like this, my caps lock and scroll lock lights blink together. I got the same -11 error message again, but this time it happened a few minutes before the freeze, the first time I started jack. I ran xmms with the alsa output plugin and after a minute or 2 the audio stopped with the message on syslog: kernel: ALSA usbusx2yaudio.c:211: usb_submit_urb() returned -11 kernel: usb-uhci.c: uhci_submit_urb: pipesize for pipe f0000 is zero kernel: ALSA usbusx2yaudio.c:211: usb_submit_urb() returned -90 kernel: usb-uhci.c: uhci_submit_urb: pipesize for pipe f0000 is zero kernel: ALSA usbusx2yaudio.c:211: usb_submit_urb() returned -90 any ideas on what this means, or other useful tests I could run? Thanks, spencer

[linux-audio-dev] [ANN] JJack 0.2 - Java for JACK update

by Jens Gulden

Hello, an update of JJack - Java bridge API for JACK has been released. http://jjack.berlios.de/ Version 0.2 integrates much better with the JACK thread architecture. The JACK processing-thread now itself executes Java code inside the Java virtual machine, after it has been attached to it calling AttachCurrentThread(..). (Thanks to Stéphane Letz for giving a hint about that.) Enjoy and make noise, Jens

[linux-audio-dev] libsndfile-1.0.11 and SD2 files

by Erik de Castro Lopo

Hi all, A new version of libsndfile was released just yesterday. I normally don't announce new versions here, but this release has one new feature which requires a bit of a special mention. With this release, libsndfile now supports the Sound Designer II file format as used by Apple Macintosh audio programs like Protools and Digital Performer. There are a couple of caveats with this format as described here: http://www.mega-nerd.com/libsndfile/FAQ.html#Q013 I now also have a Gnu Arch (like CVS but better) repository and there are some very brief instructions for accessing it here: http://www.mega-nerd.com/libsndfile/development.html I hope to expand that page in the near future. Cheers, Erik -- +-----------------------------------------------------------+ Erik de Castro Lopo nospam(a)mega-nerd.com (Yes it's valid) +-----------------------------------------------------------+ I have found that good programmers either do not make the kind of mistakes that Ada can prevent, or insert enough checks that they catch those mistakes about as efficiently as an Ada environment can. At that point, the use of Ada gives no further productivity advantage.

The great question is: Does there exist many ladspa-ui files? In case there are, the motivation to make such a library is quite high. Mathias, I have CC this to the dev-list. If you answer, please only use the dev-list. --
