[linux-audio-user] Evolution UC16 problems, modules.conf for usb-midi and usb-audio together

by m

hi all thanks for your help with compiling alsa, i've now got both usb-audio and usb-midi compiled... but i'm having problems getting midi running. the results of modprobe snd-usb-midi is a load of unresolved symbols... (as listed below)... i will also need to write a modules.conf which supports both my m-audio quattro *and* the Evolution UC16 - which i am somewhat stumped by... any help would be greatly appreciated, thanks m~ [root@hamish miriam]# modprobe snd-usb-midi /lib/modules/2.4.18-6mdk/kernel/sound/acore/seq/snd-seq-virmidi.o: unresolved sy mbol snd_rawmidi_new_Rbc1a629f /lib/modules/2.4.18-6mdk/kernel/sound/acore/seq/snd-seq-virmidi.o: unresolved sy mbol snd_rawmidi_transmit_peek_R2f3ef431 /lib/modules/2.4.18-6mdk/kernel/sound/acore/seq/snd-seq-virmidi.o: unresolved sy mbol snd_rawmidi_receive_R4b303a51 /lib/modules/2.4.18-6mdk/kernel/sound/acore/seq/snd-seq-virmidi.o: unresolved sy mbol snd_rawmidi_set_ops_R246c97c8 /lib/modules/2.4.18-6mdk/kernel/sound/acore/seq/snd-seq-virmidi.o: unresolved sy mbol snd_rawmidi_transmit_ack_Rb639865e modprobe: insmod /lib/modules/2.4.18-6mdk/kernel/sound/acore/seq/snd-seq-virmidi .o failed /lib/modules/2.4.18-6mdk/kernel/sound/acore/seq/snd-seq-virmidi.o: unresolved sy mbol snd_rawmidi_new_Rbc1a629f /lib/modules/2.4.18-6mdk/kernel/sound/acore/seq/snd-seq-virmidi.o: unresolved sy mbol snd_rawmidi_transmit_peek_R2f3ef431 /lib/modules/2.4.18-6mdk/kernel/sound/acore/seq/snd-seq-virmidi.o: unresolved sy mbol snd_rawmidi_receive_R4b303a51 /lib/modules/2.4.18-6mdk/kernel/sound/acore/seq/snd-seq-virmidi.o: unresolved sy mbol snd_rawmidi_set_ops_R246c97c8 /lib/modules/2.4.18-6mdk/kernel/sound/acore/seq/snd-seq-virmidi.o: unresolved sy mbol snd_rawmidi_transmit_ack_Rb639865e modprobe: insmod /lib/modules/2.4.18-6mdk/kernel/sound/acore/seq/snd-seq-virmidi .o failed modprobe: insmod snd-usb-midi failed -- iriXx www.iriXx.org copyleft: creativity, technology and freedom? info(a)copyleftmedia.org.uk www.copyleftmedia.org.uk _ ( ) ascii ribbon against html email X / \ cat /dev/sda1 > /dev/dsp *** stopping make sense ***

[linux-audio-user] RE: [music-dsp] linux and midi

by Joachim Backhaus

> What about using midi-thru boxes? they don't add latency to > the midi signal, > they just 'amplify' and 'split'. If you run 14 MIDI devices through one MIDI Port using MIDI Thru Boxes you get a worse timing compared to using a multiple Output Interfaces like the Steinberg Midex 8 oder the Midiman Midisport 8x8. But I don't know if there is a 8x8 Interface with Linux drivers. All of them implement a feature to reduce latency and I think that's a problem for the driver developers because the companies don't want to show the specifications for that in public.

[linux-audio-user] problem converting mp3 to wav

by Howard Sanner

I just searched the archives on this and the suggestions there didn't help. I'm trying to convert some mp3 files into wav files. First I tried having Audacity export a wav file. Then I tried loading the mp3 into Broadcast 2000 and having it render it to a wav. Finally I tried the suggestion in the archives of mpg123 -w filename.wav filename.mp3. In each case, when I tried to burn a CD from the resulting wav file, cdrecord reports "inappropriate audio coding in [filename]." I'm using Eroaster 2.0.10 as a front end to cdrecord. Audacity and Broadcast 2000 both load all these wav files and play them just fine. Anybody know what's going on here? Thanks. Howard Sanner flagstad(a)mindspring.com

[linux-audio-user] problem converting mp3 to wav

by Howard Sanner

Apparently my subscription to the list got dropped. I guess that's why things have seemed so quiet lately in Linux audio land. I just searched the archives on this and the suggestions there didn't help. I'm trying to convert some mp3 files into wav files. First I tried having Audacity export a wav file. Then I tried loading the mp3 into Broadcast 2000 and having it render it to a wav. Finally I tried the suggestion in the archives of mpg123 -w filename.wav filename.mp3.

[linux-audio-user] mpg123 and mpg321 + alsa output distorts

by Olivier

Hi all, If I use mpg123 -o oss it plays fine, but I can only use my first soundcard. If I use mpg123 -o alsa09 it plays the same volume, but the sound is distorted. mpg321 has the same problem. Programs like aplay do not have the problem, so it's not for all alsa software. what do mpg123 and mpg321 have in common? and what makes them distort when using the alsa output instead of oss-emulation? the system is a AthlonXP2000+ with Asus on-board cmipci and a Hoontech ymfpci card. Both cards have the same problem with mpg123 and mpg321 and both not with aplay. anybody an idea? thanks, Olivier

[linux-audio-user] FreqTweak 0.4.4 released

by Jesse Chappell

New in FreqTweak 0.4.4: * Now deactivates processing while switching FFT sizes. This should prevent JACK from kicking you out here. * Added ability to reconnect to JACK with a different basename, or just reconnect period if we are kicked out (I/O tab). * Control-Alt left mouse draws arbitrary lines between initial click and current cursor. Also smoothed regular drawing. * More configure checks to ensure compiling against the float version of FFTW. http://freqtweak.sourceforge.net jlc

[linux-audio-user] SSM 0.1.1 & noize farm

by Dave Griffiths

Hello all, I'm releasing a bit of an old version of SpiralSynth Modular, while work continues on the 0.2.0 version on sourceforge. It's got some rather nice features, and I should have released it months ago - but it had a crash bug I only found yesterday... anyway: Main app changes: Back to one window GUI with seperate movable areas Fixed Plugin window events/drawing bug Echo/Delay crash bug fix Less C code in SpiralSynthModular.C (Andy Preston) Ability to load ssm files from command line (Dan Bethell) gcc3.1 fixes + dynamic linking bugfix (Takashi Iwai) configure + make fixes (Takashi Iwai) Plugin changes: LFOPlugin (Andy Preston) MeterPlugin (Andy Preston) StereoMixerPlugin fix (Andy Preston) Scaling fix and name sorting for the LADSPAPlugin (Mike Rawes) Sequencer bugfix for dragging note events Matrix now 64X24 + tweaked GUI Matrix can be controlled by an external clock pulse Matrix copy/paste and transpose functionality (Andy Preston) JackPlugin fixed for recent versions of jack (Takashi Iwai) http://www.pawfal.org/Software/SSM/dload/SpiralSynthModular-0.1.1.tar.gz and if you want the cutting edge it's here: http://sourceforge.net/projects/spiralmodular : noize farm I'd also like to announce the noize farm, an open collection of ssm patches that are shared in the spirit of the GPL: http://groups.yahoo.com/group/noize_farm/ Feel free to download, hack, modify, upload and generally have fun with anything you find there. It's currently hosted at yahoo, which means you have to sign up with them to get access to the files - but we think it's worth the hassle for now. I don't see it as being restricted to just ssm patches either, if you like the idea then you can share anything (linux) audio related - as long as the files are small, and open for all to play with. All the best, Dave : www.pawfal.org :

[linux-audio-user] usb midi question...

by m

hi all, got a quick q about usb midi in alsa... i've already built my alsa-driver (0.9.rc3) for snd-usb-audio, to run my quattro.... but i've just been given an Evolution UC-16 on trial, which is usb midi. so normally, i'd rebuild my alsa-driver ./configure --with-cards=usb-audio --with-cards=usb-midi but it will only ever build just one of the drivers if i do that (usually the last one in the list)... is there a way i can build usb-midi *and* usb-audio? i'll probably be doing quite a bit of testing with usb-midi, but will mostly be running usb-audio for my own use. or is it possible to build the alsa-driver for usb-midi and manually copy it into place? thanx in advance m~ -- iriXx www.iriXx.org copyleft: creativity, technology and freedom? info(a)copyleftmedia.org.uk www.copyleftmedia.org.uk _ ( ) ascii ribbon against html email X / \ cat /dev/sda1 > /dev/dsp *** stopping make sense ***

[linux-audio-user] Speaker Jack

by linuxmedia4＠netscape.net

Greetings, I just bought a new system. It has integrated sound on the Mother Board. There is a jack marked "spk" (obviously the speaker jack). But the manual refers to that jack as "line-out" I was always under the impression (just an assumption) that "line-out" and the speaker jack put out completly different voltage levels (and we know how dangerous it could be to plug things into the wrong voltage levels). Are the standard speaker jacks indeed "line level"? There's several possiblities that I can think of: 1. The standard "speaker out" jack complies to the "line level" standard 2. Since it's a costom made computer, the jack is incorrectly marked and its actually a line out jack. (after all, the VGA port is marked as "COM2") 3. Since the manual covers several versions of their Mother board, it's actually a different interface that it's referring to (I've run into this with the manual before). I'm actually hoping to find out that the speaker out jack complies to the line level standard. This way I can use the speaker out for line level devices. Let me know what you know, Thanks, Rocco __________________________________________________________________ The NEW Netscape 7.0 browser is now available.
