[linux-audio-user] Can't set input monitoring with ice1712 based card.

by Luke Yelavich

Hi folks I have compiled the latest 0.9rc of ALSA, on a system with kernel 2.4.20 patched with low-latency and pre-emptable kernel patch. I have a TerraTec DMX 6Fire 24/96 soundcard, which uses the Envy24 chipset. The card uses the snd-ice1712 module. I execute jack like this: jackd -d alsa -d hw:0 -p 512 -r 44100 & Jack starts fine, however when I try and run a client, in this case ZynAddSubfx, I occasionally get xruns, and a message saying "Cannot set input monitoring (No such file or directory)" I am unable to jack ZynAddSubfx to ALSA, as the jack portion of alsa-patch-bay tends to time out while attempting to patch the program. I am running all of this as root. Any ideas or suggestions are welcome. Thanks Luke (TheMuso)

[linux-audio-user] jackd, zynaddsubfx and iiwusynth

by Levi Burton

Hello, Has anyone gotten zynaddsubfx and/or iiwusynth to work with jack? The programs fire up fine, but they output no sound. I have tried zynaddsubfx 1.0.9 and the most recent cvs of iiwusynth (fluidsynth). I know i am calling jackd properly, because alsaplayer works fine with jackd, as well as ecasound. -- Levi Burton http://www.puresimplicity.net/~ldb/

[linux-audio-user] ALSA - software mixing docs.

by Patrick Shirkey

I have added some info to the asoundrc docs on using the new dmix plugin http://www.alsa-project.org/alsa-doc/doc-php/asoundrc.php3?company=Generic&… It allows software mixing of multiple streams at one time in a similar way to ESD,ARTS,JACK. Currently it is only available with latest cvs so needs testing with various apps to make sure it works as desired. -- Patrick Shirkey - Boost Hardware Ltd. Http://www.boosthardware.com Http://www.djcj.org - The Linux Audio Users guide ======================================== Being on stage with the band in front of crowds shouting, "Get off! No! We want normal music!", I think that was more like acting than anything I've ever done. Goldie, 8 Nov, 2002 The Scotsman

[linux-audio-user] MIDI -???- setup

by Tim Hall

Hello I'm still having trouble configuring sound for my box. I'm using the 2.4.18-596-demudi kernel and ALSA-0.9beta ... that comes with the distro. I've successfully loaded my soundcard modules (by hand). But still no Joy. I checked /proc/asound and all the inormation is there for both soundcards - ESS Solo-1 and an sbawe64 all present and correct, although I've not checked the /proc/asound files exhaustively.The /dev/snd directory is present also. As you see I have minimal / low powered setup. I need to be able to access my external synthesiser keyboard (an old Roland D10) and I'd like to use MusE / Rosegarden-4 to edit my MIDI files. I'm not expecting wonders, but I do think it's possible without having to revert to OSS. It's clear that something is not configured right, some essential link in the chain is missing or misdirected, but what? It would be useful to know what these config utilities are supposed to do. I don't know what to do next. Please tell me if there's something obvious that an experienced user would have done in these circumstances. Or if I could be asking better questions or offering more focused information. How do you define an $AUDIOSERVER? cheers tim hall What follows is a healthy portion of Luncheon Meat fyi - please prompt me if you need more | less focussed information than this. ***************************************************************************** Errors: Magpie can't parse the infolines so puts all demudi apps into 'unspecified' category - this isn't of course a major problem. Back at my desktop menu (I'm using fluxbox) Midi connection panel gives 'Error opening sequencer' MusE fails to open and proceeds to thrash the cpu at 99% for some reason. Alsa Mixer: function snd_ctl_open failed for default: Unknown error Jack connection panel won't open. Jack Audio server brings up an xterm flashes text too fast to read and then exits. AlsaPlayer tells me that there's no $AUDIOSERVER GEM rather rudely hung the system. Soundcard detection semi-works: giving: """ Storing ALSA mixer settings ... :done Shutting down ALSA sound driver (version 0.9.cvs20021017) :done Starting ALSA sound driver [..] :es1938 es1938 :done Restoring ALSA mixer settings :done Incorrect password. Try again? (y/n) """ It rewrites /etc/alsa/modutils/0.9 to launch two instances of es1938, overwrting sbawe for card1 (???) amixer on the command line produces lots of text output. If I try to cat anything to /dev/snd/pcmC0D0p, I get: cat: write error: File descriptor in bad state. /var/log/messages doesn't have much to say except for a few lines of: kernel: snd_es1938_write_cmd timeout (0x02c0/0x0280) **************************************************************************** *************************************************************************** Contents of relevant /proc/ files: [--] Contents of /asound/...

[linux-audio-user] irq tuning

by R Parker

Hi, I ran accross a kernel module/tool titled irqtune. >From it's web page: #How do I know if I need irqtune? <snip> # Interrupt handlers for specialized, time critical devices don't get control when they need to. Perhaps it's just what the realtime audio admin needs. I don't recall reading about it in our mailing lists. Has anyone else looked at it? Thoughts? ron __________________________________________________ Do you Yahoo!? Yahoo! Tax Center - forms, calculators, tips, more http://taxes.yahoo.com/

I think you mean makeup gain here. Its genreally used to boos t the signal level given a particularly heavy compression, but hypothetically you could use it to reduce too. - Steve

[linux-audio-user] building new machine, couple simple questions

by R Parker

Hi, I'm building a new low latency + preemption patched machine. I've forgotten how to confirm that the kernel is running preemptively. It's a command to the effect of 'cat /proc/something'. Anyone know what I'm referring to? Also, can someone point me to docs for enabling/using a capabilities enabled kernel? Enabling normal user capabilities for jackd is my objective. I believe Fernando has this included in the CCRMA stuff but a quick google didn't find any docs. They're probably there. Hints appreciated. I'll search LAD archives...it's probably all there. Jan, your link to Paul Winkler's Low Lowlatency docs at boosthardware are brooken. Thanks, ron __________________________________________________ Do you Yahoo!? Yahoo!

[linux-audio-user] batch processing of time stretching

by Mark Knecht

Hi, Ardour recently added a feature for time stretching audio, which as I understand it, was Open Source code from somewhere else. I have about 2000 Acid Pro loops that would be more useful to me if they had slightly different properties than they were shipped with. Is anyone working on a batch processing mechanism for dealing with many, many wave files? Sonic Foundry offers this in their programs. Is there any equivalent in Linux. (I'm not talking about writing scripts or bash processing or anything like that.) Thanks, Mark
