[linux-audio-user] JACK - how to connect to nforce2 spdif ?

by Ruben Jenster

Hi, I want to use the JACK soundserver. I'm able to connect to the normal analog output but not to spdif. I use the snd-intel8x0 driver for my onboard nforce2 soundchip. > ash-2.05b# cat /proc/asound/devices > 1: : sequencer > 0: [0- 0]: ctl > 18: [0- 2]: digital audio playback > 25: [0- 1]: digital audio capture > 16: [0- 0]: digital audio playback > 24: [0- 0]: digital audio capture > 33: : timer > bash-2.05b# Using the alsa output plugin in xmms I can choose hw:0,2 then the sound comes out through spdif, but I don't know how to do this with JACK. I tried qjackctl (grafical controller for JACK and ALSA) and qjackconnect (grafical patchbay) and via console by typing 'jackd -d alsa -d hw:0,2' (same with hw:1 and hw:2) but this doesn't work, neither as user nor as root. via console I get the following output: > ash-2.05b$ jackd -d alsa -d hw:1 -S > > jackd 0.98.1 > Copyright 2001-2003 Paul Davis and others. > jackd comes with ABSOLUTELY NO WARRANTY > This is free software, and you are welcome to redistribute it > under certain conditions; see the file COPYING for details > > loading driver .. > creating alsa driver ... hw:2|hw:2|1024|2|48000|0|0|nomon|swmeter|-|16bit > jackd: pcm.c:690: snd_pcm_nonblock: Assertion `pcm' failed. > Abgebrochen > bash-2.05b$ qjackctl displays following errors: > 13:16:14.915 /usr/bin/jackd -R -dalsa -dhw:0,2 -r48000 -p1024 -n2 -S -i2 > -o2 13:16:14.936 JACK was started with PID=12828 (0x321c). > jackd 0.98.1 > Copyright 2001-2003 Paul Davis and others. > jackd comes with ABSOLUTELY NO WARRANTY > This is free software, and you are welcome to redistribute it > under certain conditions; see the file COPYING for details > loading driver .. > apparent rate = 48000 > creating alsa driver ... hw:0,2|hw:0,2|1024|2|48000|2|2|nomon|swmeter|-| 16bit > ALSA lib pcm_hw.c:1155:(snd_pcm_hw_open) open /dev/snd/pcmC0D2c failed: No such file or directory > jackd: pcm.c:690: snd_pcm_nonblock: Assertion `pcm' failed. > 13:16:14.994 JACK was stopped successfully. > 13:16:16.966 Could not connect to JACK server as client. Is there some special configuration needed in '/etc/asound.conf' Please help me, if it works I want to write a howto in the gentoo user forum cause there is to little information about JACK and JACK is definitly a great leap forward considering the sound quality.

[linux-audio-user] USB Audio has played but no longer does so.

by Chris Lyon

Dear all, Roland UA-100 plugged into PC, usbview detects interface. aplay -l doesn't report any knowledge of the device. I believe I have loaded the appropriate modules, snd-usb-audio but the system resolutely refuses to make music as it has before. I would include the appropriate modules.conf files to show but this E-mailing machine and the linux box are not connected and I feel cross reading would be a little error strewn. Can anyone outline a procedure for checking at which point a problem might occur and, if possible, a list of command line utilities that can reveal precisely what components are loaded. Is it possible to load modules incompletly such that a component identifies it's presence but isn't actual functioning. If this is so how does one check the dependancies? I understand that amix and alsamixer won't recognise the presence of a USB connected audio interface, is this the case? Any help appreciated. Chris Lyon

Re: [linux-audio-user] audigy2 zs

by Peter Zubaj

Hi, planetccrmaFC1 uses alsa ??? If yes, then run alsamixer and set "Line In" volume and "Analog Mix" volume. Do not use Mic In as Line In. Peter Zubaj ____________________________________ http://www.pobox.sk/ - spolahliva a bezpecna prevadzka

[linux-audio-user] building fst fails at make install step

by Mark Knecht

Hi, I'm trying to follow Dave's instructions for building fst-1.6 http://www.djcj.org/LAU/quicktoots/toots/vst-plugins/ at the section called "Building and Installing the fst System" on my Gentoo laptop. Here's wht I'm doing: flash VST $ tar xvfz fst-1.6.tar.gz flash VST $ cd fst-1.6 flash fst-1.6 $ mkdir vst flash fst-1.6 $ cd vst flash vst $ cp /home/mark/vstsdk/vstsdk2.3/source/common/aeffectx.h . flash vst $ cp /home/mark/vstsdk/vstsdk2.3/source/common/AEffect.h . flash vst $ cd .. flash fst-1.6 $ ./fixheaders sed: can't read aeffectx.h: No such file or directory flash fst-1.6 $ cd vst/ flash vst $ ../fixheaders flash vst $ cd .. flash fst-1.6 $ ./autogen.sh flash fst-1.6 $ ./configure <SNIP> config.status: creating fst/Makefile config.status: creating fst/include/config.h Configure finished. Do 'make' to build the project. flash fst-1.6 $ make <SNIP> gcc -c -I. -Iinclude -I/usr/include/wine/windows/.. -I/usr/include/wine/windows/../.. -I/usr/include/wine/windows -g -O2 -fPIC -I .. -I./vst -DDLLPATH=\"/usr/lib/wine\" -DLIBPATH=\"/usr/local/lib\" -D_REENTRANT -o fstconfig.o fstconfig.c gcc -o fstconfig fstconfig.o -L. -lfst make[1]: Leaving directory `/home/mark/data/VST/fst-1.6/fst' flash fst-1.6 $ su - Password: root@flash ~ # cd ~mark/data/VST/fst-1.6 root@flash /home/mark/data/VST/fst-1.6 # make install /bin/sh ./mkinstalldirs /usr/local/lib/pkgconfig ./mkinstalldirs: ./mkinstalldirs: No such file or directory make: *** [install-pkgconfigDATA] Error 127 root@flash /home/mark/data/VST/fst-1.6 # Can anyone tell what I'm doing wrong here? There is the one mistake in the instructions on the QuickToot page where it seems to tell me to run fixheaders from the wrong place, but I haven't figured out how to get past this. I was able to build fst-1.5 quite awhile agio but of course have forgotten the trick. Thanks, Mark

Re: [linux-audio-user] RPMs for new Distro...Yoper Linux

by Dan Harper

Oh yeah... Don't think of committing lightly, yesterday I tested it out on a machine and managed to lose the ability to boot into Windows. And in the end I couldn't even boot into Yoper as there was no option to make a boot disk and making one manually also failed. It's install process is very nasty and unintuitive, that part definitely needs a lot of work. I can't say about the rest because I haven't gotten that far yet!

[linux-audio-user] SoftSynth/Sampler Automation

by Iván Almada

what about soft synthesizer sampler automation? this is a very important point in my opinion, controlling filters via lfo is not the best way to do that all the time ... automating knob movements gives a hell lot more of control so which are the ways to do this ??? midi cc (continous controllers) ??? in that case anybody has a map of the controllers for some synths (ZynAddSubFX for example ) ...? is it possible to draw automation curves directly inside sequencers like rosegarden which support any kind of softsynth plugins like dssi ??? how do you guys get that automation stuff done?? ivan. _________________________________________________________ Do You Yahoo!?

[linux-audio-user] Specimen SoftSampler

by Iván Almada

hi, a question about specimen: Pete: ive been working with your sampler and would like to draw automation curves from rosegarden in order to make filter sweeps in specific points of my song, which is very difficult to sync with lfos... so parameter automation comes handy in that situations... so, does specimen respond to midi cc parameters for controlling the filter cutoff for example ? also, youve been working on specimens GUI and routing?? the independent outputs is great!!! so you can add reverb to snare or claps without disturbing the mr Bassdrum... and about the GUI: it would be great if you could change those parameter number boxes with sliders or knobs... in fact specimen is the first sampler with "number" boxes ive seen, i was very used to classic circular knobs... though thats not a big issue ... and which is the best way to record specimens audio output... so i can render the wav audio and edit with ardour... thanx. ivan. _________________________________________________________ Do You Yahoo!?

[linux-audio-user] awe64 - how do I use on-board chorus and reverb?

by Paul Berry

Hello I am hoping someone can help me with my awe64. I would like to use the on-board reverb and chorus that the sound card has but I am unable to figure out how to do this. I have installed awesfx-0.5.0d, am using ALSA 1.0.6 on a redhat 8.0 machine. I can load sound fonts fine using sfxload but the -r & -c options, aweset & setfx don't seem to do anything. Thanks for any help, Paul

[linux-audio-user] terratec aureon 5.1 usb and jack

by Sebastian Gutsfeld

Hi, recently I bought a Terratec Aureon 5.1 USB for my Thinkpad R32 (has an Intel 82801CA-ICH3 onboard). The Intel is card 0, the Terratec card 1. I have no problems playing some MP3s with xmms or "alsaplayer -d hw:1 -d 1024" (although I don't know why I have to use "-f 1024", I just played with the parameters) over the Terratec. But whenever I play through jack the sound begins to crackle, which is really annoying. Here are my module configurations: ,---- | alias char-major-116 snd | alias char-major-14 soundcore | | options snd major=116 cards_limit=4 | | # intel8x0 | 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-intel8x0 | alias snd-card-1 snd-usb-audio | alias snd-card-2 snd-virmidi | alias snd-card-3 snd-usb-audio | | alias sound-slot-0 snd-card-0 | alias sound-slot-1 snd-card-1 `---- And here is how qjackctl starts jackd: ,----[ .jackdrc ] | /usr/bin/jackstart -R -dalsa -dhw:1 -r48000 -p256 -n2 -S `---- Jack output: ,---- | back from read, ret = 1 errno == Success | jackd 0.98.1 | Copyright 2001-2003 Paul Davis and others. | jackd comes with ABSOLUTELY NO WARRANTY | This is free software, and you are welcome to redistribute it | under certain conditions; see the file COPYING for details | | loading driver .. | apparent rate = 48000 | creating alsa driver ... hw:1|hw:1|256|2|48000|0|0|nomon|swmeter|-|16bit | control device hw:1 | configuring for 48000Hz, period = 256 frames, buffer = 2 periods `---- Kernel 2.4.25 with CAT_SETPCAP patch but no low latency patch. BTW, I have no crackling sound using jack with the Intel. Hopefully someone can help me with my problem. Sebastian
