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. Here's a nice big log. ----- lsusb -v (before) Bus 001 Device 010: ID 0763:2805 Midiman Device Descriptor: bLength 18 bDescriptorType 1 bcdUSB 1.00 bDeviceClass 254 Application Specific Interface

[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

[linux-audio-dev] M-Audio Sonica/Ozone/MobilePre/Transit firmware loader now works

by Clemens Ladisch

Hi, it has been reported that the 2.6.8 kernel has fixed the handling of USB resets, so now it's possible to use a Linux firmware loader to get these devices to work. You can get the loader at <http://usb-midi-fw.sf.net/>. Best regards, Clemens

This may sound strange, but I think this is the normal behaviour. Just ignore the message. Is there a problem besides this? (which reminds me, have to release a new version of vstserver soon) --
