[linux-audio-user] Terratec DMX 6Fire 24/96 - Startup Messages

by David Haggett

All I got one of these cards a few months ago. Sound production is really good, and it plays nicely with jack and alsa, but I get the following messages in the log every time I start my PC. I've updated from SuSE 9.1 to 9.3 (64bit on AMD64), but the messages persist. Consumer PCM code does not work well at the moment --jk ALSA sound/pci/ac97/ac97_codec.c:1916: AC'97 0 does not respond - RESET ALSA sound/pci/ac97/ac97_codec.c:1925: AC'97 0 access is not valid [0xffffffff], removing mixer. ice1712: cannot initialize ac97 for consumer, skipped I also notice that kamix/qamix doesn't have a volume slider. Is this "normal" behaviour for this card or is there anything I can do to make things "better"? -- David Haggett

I have used midicomp plus awk/python to do some of these things, (and midicsv which does a very similar job to midicomp) but there are some limitations to do with midi itself that makes some of the transformations I'd like to do very difficult. For example, midi has no idea about bars/beats, but with the time signature info in type 1 midi files you can map ticks to bars/beats/ticks and so on, but it's not trivial. The main problem is that midi files are streams of event data, not musical information, and extracting the musical information sensibly is tricky. For example, in a midi drum track, there might be a pan controller before every note_on event to set the pan individually for each drum. So if you are going to move the note_on event backwards or forwards in time, you need to make sure that the pan event moves with it. You also need to make sure that you don't get overlaps between notes and mess up the note_on/note_off order. It looks like a scripting based solution is my best bet, with some sort of awk-like language for specifying transformations. I think I'll have to get stuck into my python code and see what happens. Cheers, Stuart

[linux-audio-user] How can I get a MIC capture on a CA0106 soundcard?

by Flash Love

I have been trying to troubleshoot a linux system similar to my system with FC3 and rhfc3.ccrma that is having sound problems. The system with the problem have two sound cards: CA0106 (card0) and EMU10k1 (card1). Among other mysteries, I am particularly stumped trying to determine what conflict exists when: 1) aumix: no device found 2) aumix -d /dev/mixer -q : no device found (when /dev/mixer exist) 3) alsamixer -c0: there is no MIC 4) there truly seems to be a misconfiguration somewhere which points the pcm devices of the sound cards i.e. audio output directed to card1 (/dev/dsp1) is actually delivered to card0. Below is output from aadebug. Any pointers will greatly be appreciated.

[linux-audio-user] Suse 9.2

by Brian Redfern

I wound up switching to demudi, because all the audio apps are setup from the get-go to work great, and now I figured out that Muse was configured to run without jackd running first, that's why I was having some trouble there, but everything is working great. --- linux-audio-user-request(a)music.columbia.edu wrote: > Send linux-audio-user mailing list submissions to > linux-audio-user(a)music.columbia.edu > > To subscribe or unsubscribe via the World Wide Web, > visit > > http://music.columbia.edu/mailman/listinfo/linux-audio-user > or, via email, send a message with subject or body > 'help' to > linux-audio-user-request(a)music.columbia.edu > > You can reach the person managing the list at > linux-audio-user-owner(a)music.columbia.edu > > When replying, please edit your Subject line so it > is more specific > than "Re: Contents of linux-audio-user digest..." > > > Today's Topics: > > 1.

[linux-audio-user] VirMIDI output ports don't work

by Sebastian Gutsfeld

Hi LAU, I recently discovered that the output/readable ports of VirMIDI don't send any MIDI messages but the input/writable ports of VirMIDI still work. Here's an example setup: MIDI keyboard -> VirMIDI 2-0 VirMIDI 2-0 -> synth This doesn't work, whereas when starting csound4 listening to the input port VirMIDI 2-0 (with "-M /dev/snd/midiC2D0") and only making the MIDI keyboard -> VirMIDI 2-0 connection everything works fine. I use Debian testing, with alsa version 1.0.8 and here's my modules config for alsa: ,---- | alias char-major-116 snd | alias char-major-14 soundcore | | options snd major=116 cards_limit=5 | | # emu10k1 | alias sound-service-0-0 snd-mixer-oss | alias sound-service-0-1 snd-seq-oss | alias sound-service-0-3 snd-pcm-oss | alias sound-service-0-8 snd-seq-oss | alias sound-service-0-12 snd-pcm-oss | | # terratec aureon | alias sound-service-1-0 snd-mixer-oss | alias sound-service-1-3 snd-pcm-oss | alias sound-service-1-12 snd-pcm-oss | options snd-usb-audio vid=0x0ccd index=1 | | alias /dev/dsp* snd-pcm-oss | | alias snd-card-0 snd-emu10k1 | alias snd-card-1 snd-usb-audio | alias snd-card-2 snd-virmidi | alias snd-card-3 snd-usb-audio | alias snd-card-4 snd-usb-audio | | alias sound-slot-0 snd-card-0 | alias sound-slot-1 snd-card-1 | | post-install snd-emu10k1 modprobe snd-emu10k1-synth `---- Any ideas? regards, Sebastian

[linux-audio-user] re: Does anyone have a working example of Supercollider and SCUM GUI where slider or a button does real-time update on the synth

by Ivica Bukvic

Hi all, I just realized why my example code "didn't work." It was a simple stupid human error (surprise, surprise), the change did occur, it was just that the sinetone was 400Hz and I was altering it by 0-1 Hz with slider output which on my lousy laptop speakers in a noisy room seemingly did not make a bit of difference (at least not to my ears :-). Anyhow, thank you very much all for your help in this matter! Btw, Stefan, you mentioned that there were some updates to SCUM. Are these included in the latest 0.0.2a version? Also is this the same version like the one presented at LAC last year? Many thanks! Best wishes, Ico

[linux-audio-user] emu10k1-synth module not loaded

by vescovi christophe

Hi all, I have a problem I already had with my previous mdk 10.1 setup with my new debian one. I have a sblive, debian unstable, kernel 2.6.12rc4 + lsm, alsa 1.0.8 and the alsa script does not start the emu10k1-synth module when starting the midi modules. I have try to add : post-install snd-emu10k1 modprobe snd-emu10k1-synth in /etc/modutils/alsa, then update-modules but it does not work. Do you know how how I could load this module at boot time (of course modprobe snd-emu10k1-synth works ....) Christophe

[linux-audio-user] RE: [linux-audio-dev] Does anyone have a working example ofSupercollider and SCUM GUI where slider or a button doesreal-time update on the synth

by Ivica Ico Bukvic

Many thanks for the reply! Actually there is another, very odd reason why my example did not work. Even if I used your working example, I found out the following odd behavior: If I have a statement that does: Out.ar(out, SinOsc.ar(freq, mul: 0.5)) Then it works. If I have a statement that does: Out.ar(out, SinOsc.ar(freq * 100, mul: 0.5)) This also works. Now if I have: Out.ar(out, SinOsc.ar(freq + 100, mul: 0.5)) This doesn't. Naturally, one could always put something before this statement to fix this, i.e.: freq = freq + 100; Out.ar(out, SinOsc.ar(freq, mul: 0.5)) But it is still interesting why the multiplication works and addition doesn't. Also, I noticed that on one of your SCUM example screenshots you are using .connect method to connect something, yet I was unable to locate anything of value in the documentation. I assume that this could be something similar to the signal-slot idea in Qt and/or other Widget languages (but obviously I may be completely off the mark), so I was wondering if you could please provide an example for that? I would really appreciate it! Finally, while I am on the roll with questions :-), do you mind also mentioning what's the current status/roadmap of SCUM in terms of supporting all stock Supercollider widgets, as I noticed that the SCUM widgets use non-standard names and in addition I am not sure whether all widgets are as of yet supported, all of which, at least in my experience, makes a number of sc examples available on the net difficult if not impossible to run in Linux. Please don't get me wrong, this is not to criticize as I am eternally grateful for SCUM, I am simply curious as to what is the roadmap for the project. Many thanks to all for your help!

[linux-audio-user] hdsp, multiface, xine, mplayer, dvd

by D. Sen

This might be a trivial question but I am having trouble configuring xine and mplayer to play multichannel audio (from a DVD) through a RME-Multiface configuration. Two channel output (stereo) works fine. I have tried setting xine to "5.1 channel output", etc...but nothing seems to work. I know the multiface works as I have written some simple code to send audio to the 8 analog channels. Any help with configuring Xine/Mplayer would be much appreciated. DS
