[linux-audio-dev] xruns, VP kernel, interrupts

by John Hedditch

Hi all. Does anyone have any ideas on what this message means: Unexpected hw_pointer value [1] (stream = 0, delta: -106, max jitter = 128): wrong interrupt acknowledge? It seems to accompany the xruns I get with the 2.6.9-rc2-mm4-VP-S7 kernel. Otherwise, this gives the best results I've yet got with jack. Incidentally, has anyone ever had an xrun-free system with jackd -R -d alsa -p64 ? Cheers, John

[linux-audio-dev] LAC 2004 recordings now online

by Joern Nettingsmeier

hi everyone! thanks to the work of stephan römer at zkm, the recordings of the linux audio conference 2004 are now completely edited and tagged. they are being uploaded as i type. you will find them at http://linuxaudiodev.org/contrib/zkm_meeting_2004/recordings/ , the corresponding slides are at http://linuxaudiodev.org/contrib/zkm_meeting_2004/slides/ . best regards, and sorry it took so long (my responsibility), jörn ps: if you have more photos, recordings or other lac memorabilia to share, throw them my way so that i can upload them. -- "90% of all networking problems are routing problems. 9 of the remaining 10% are routing problems, but in the other direction.

Thanks tons, i shall start coding it one monday! (i have an exam on monday so not earlier) Now i just have to decide on using thinksynth or galan for the prototype :-) Last time i tried galan it was too fast on my machine... a p3 650...but i'm hopeful! > > > > someone on #lad told me about that. > what do you mean with to fast ? > > do you mean galan-0.3/include/generator.h:24 > > > #define SAMPLE_RATE 48000 ??? > > my interface only does 48k and i am not proud, that its still hardcoded > but ;) > Opps, sorry, typo there.... Too slow... makes much more sense now, as in my wimpy p3 650 does not really cope with Galan too well. Simple patches seem to use a lot of cpu so i don't know how doing more complex patches in it would be. I have enough trouble running Muse and Zyn at the same time. Work on the drum synth will be starting soon, i was slowed down by my laptop catching on fire on tuesday. ;-) At this stage i'm thinking of copying the circuits for the good ones in the TR series, the non-sample based simmons, and the techniques on the SOS site for tuned drums. Anything else anyone is keen on? A drum synth they can't live without? Or any particular drum sounds? Dmitry, and I have decided on a name, but you'll here it when the code is done. Loki

[linux-audio-dev] [ANN] Specimen v0.4.4

by Pete Bessman

Normally, I don't announce minor releases, but this is an exception. The latest Specimen has a completely redone GUI, which I hope will make using it suck a whole lot less. Downloads: www.gazuga.net/downloads.php Screenshots: www.gazuga.net/screenshots.php This version of Specimen also relies on PHAT, so be sure you have the latest version (0.2.2). PHAT: www.gazuga.net/phat.php This is a relatively ambitious endeavor, so please inundate me with bug reports. And yes, MIDI control is coming really, really soon. Seriously. --Pete

[linux-audio-dev] Apple's distributed audio processing technology

by Kai Vehmanen

As seen on slashdot: http://www.apple.com/logic/distributedaudio.html ""Simply add one or more Macintosh systems via Ethernet (or FireWire) connections to your Logic Pro 7 system. The result is an audio and music production system with processing power that was previously unimaginable for native-based systems."" No details about the protocols used. Gigabit ethernet is recommended for "the best performance". Pretty interesting stuff to say the least. -- http://www.eca.cx Audio software for Linux!

Re: [linux-audio-dev] M-Audio Sonica/Ozone/MobilePre/Transit firm ware loader now works

by Stephen Hassard

I just played around with my Sonica a little more (on i386) and found that after the firmware upload was attempted, madfuload was unable to reset the device. It looks like the device auto-reset, as the USB device changed (increment by one). The usb IDs have also changed.

[linux-audio-dev] VP kernels

by Dmitry Baikov

Hello! I'm not subscribed to LKML, so positng here. Anyone tried 2.6.9-rc2-mm1-VP-S3? In two words: no luck. i8042 does not work at all (have an usb kbd hopely). Nvidia-61.11 does not modprobe (unresolved symbols), but builds . 2.6.9-rc1-VP-S0 works fine. except for few lockups after writing cds (may be not kernel, but xorg-6.8.0). Any comments? -- Dmitry.

[linux-audio-dev] Linux/Alsa Tascam US-122 Issues

by Antonio Willy Malara

hello everybody! i've finally got an usb-audio card for my linux audio madness, i've taken a tascam us122, beacuse of the good support it has, infact i was able to use it, i've not tested it extensively because i was moving and my laptop had a desperate need of a reinstalling :P i've reinstalled this ibook with a net-installed debian sid and the first thing i've done was compiling the same alsa and kernel versions, linux vanilla 2.6.8.1 and alsa-driver 1.0.6a, alsa-lib 1.0.6 but all alsa wont work... with the internal powermac audio card (which was working) i got a undefined referece, in compile time (but not fatal, since the module is compiled) and in inserting time: Zeryn:/home/willy# modprobe snd-powermac snd_powermac: Unknown symbol num_controls Zeryn:/home/willy# but i can live without it, i have the oss module and i plan to not use it anymore, because the tascam card will be conencted to everything in my setup, but the strangest things happened when i tried to plug the usb-usx2y module: a variety of freezes, kernel panics, oops, so i've tried to compile different versions of alsa and kernel, i've tried combinations of: linux 2.4.27, 2.6.8, 2.6.7, 2.6.9-rc2, 2.6.9-rc2-bk9 alsa 1.0.6, 1.0.6a, 1.0.7rc1, alsa-cvs (alsa cvs was broken) now i got the same error over and over again, the hotplug scrits are loading the firmware, the module is correctly loaded and the card is powering up well and the usb led keeps to stay on, but, when i try to launch jack or an audio application i got some messages regarding "sequence errors" and i have to kill the application via ctrl-c, if i restart the application i have a freeze (no kernel panics or such) this is the kernel log from kernel module loading to the freeze --- Sep 26 05:34:27 (none) kernel: usbcore: registered new driver snd-usb- usx2y Sep 26 05:34:37 (none) kernel: ohci_hcd 0001:01:18.0: wakeup Sep 26 05:34:37 (none) kernel: usb 1-1: new full speed USB device using address 2 Sep 26 05:34:38 (none) kernel: usb 1-1: USB disconnect, address 2 Sep 26 05:34:39 (none) kernel: ohci_hcd 0001:01:18.0: wakeup Sep 26 05:34:40 (none) kernel: usb 1-1: new full speed USB device using address 3 Sep 26 05:35:12 (none) kernel: ALSA /home/willy/Pacchi/alsa/alsa- driver-1.0.6a/kbuild/../usb/usx2y/../../alsa-kernel/usb/usx2y/ usbusx2yaudio.c:30 4: Sequence Error!(ep=10;nuc=0,frame=34039) Sep 26 05:35:12 (none) kernel: ohci_hcd 0001:01:18.0: bad entry 50ce000 Sep 26 05:35:19 (none) kernel: ALSA /home/willy/Pacchi/alsa/alsa- driver-1.0.6a/kbuild/../usb/usx2y/../../alsa-kernel/usb/usx2y/ usbusx2yaudio.c:37 0: timeout: still 9 active urbs..

[linux-audio-dev] [ANN] Q multimedia examples released

by Dr.Graef＠t-online.de

Q is a functional programming language based on the term rewriting calculus, see http://q-lang.sourceforge.net for details. This release provides a collection of sample multimedia programs written with Q: - QAudioPlayer, an audio player with waveform and FFT display - QMidiCC, a MidiShare patchbay and transport control - QMidiPlayer, a MidiShare-based MIDI player - QSCSynth, a GUI frontend for SuperCollider These programs also demonstrate how to embed a Q application in a KDE/Qt GUI. A recent KDE version is required (3.2 has been tested). And you'll need the Q core and multimedia packages, of course. Descriptions, screenshots and download links can be found here: http://q-lang.sourceforge.net/examples.html Download, for the impatient: http://sourceforge.net/project/showfiles.php?group_id=96881&package_id=1309… Besides this, there are also new releases of Q-Audio (which now uses PortAudio v19, with support for Alsa and Jack) and Q-Synth (fixes for compatibility with recent SuperCollider versions in CVS). Moreover, FC1 and SuSE 9.1 RPMs for PortAudio v19 and SuperCollider are now also available for your convenience. See http://q-lang.sourceforge.net/download.html Enjoy! -- Dr. Albert Gr"af Dept. of Music-Informatics, University of Mainz, Germany Email: Dr.Graef(a)t-online.de, ag(a)muwiinfa.geschichte.uni-mainz.de WWW: http://www.musikwissenschaft.uni-mainz.de/~ag
