[linux-audio-user] ams, jackd & X as root? on debian

by Eric Dantan Rzewnicki

hello, I have jack installed and working now. So, now I'm trying to get AlsaModularSynth compiled and running. Has anyone else accomplished this in debian stable (woody)? I installed libqt3-mt (along w/everything it depended upon), fftw-dev, fftw2, sfftw-dev, sfftw2 and ladspa-sdk to get ladspa.h. I've tried to edit the top of make_ams to agree with the location of the qt3 libs, bin and include directories on my system as best as I could figure ... but I'm not sure I got it right: QT_LIB_DIR=/usr/lib/qt3/plugins/styles QT_BIN_DIR=/usr/share/qt/bin QT_INCLUDE_DIR=/usr/include/qt it seems to compile OK when I do: make -f make_ams though there are a lot of warnings about comparing signed to unsigned and other warnings that flew by. Are these benign? Anyway. I end up with an executable ams. When I run ./ams I get this: ./ams: error while loading shared libraries: libjack.so.0: cannot open shared object file: No such file or directory I have that in /usr/local/lib/libjack.so.0 so creating this link appears to help: box1:/usr/lib# ln -s /usr/local/lib/libjack.so.0 libjack.so.0 Is that the correct sollution? but, now: box1:/home/eric/audio_code/ams-1.5.5# ./ams ams: cannot connect to X server I assume this is because X is running as me (eric) and not as root. I'll try getting out of X and starting it as root as soon as I finish writing this message. But, is there a way to let root connect to the X server that's running as eric? I was sort of ok (well, not really, but I'm giving it a try) with the idea of running jackd and its clients as root ... but, running X as root, too? that makes me more nervous, somehow... maybe I shouldn't be nervous about that ... I'm not sure. anyway. i'll give it a shot with a root X session. I'm thinking that maybe I should patch and recompile the kernel and recompile jack to enable capabilities so I don't have to run as root. Do those of you running jackd as root also run your X session as root? Thanks for listening, Eric Rz. PS If all of this has been covered before and my questions are annoying you, feel free to send me to the archives. I try to follow jackit-devel, but most of it seemed to go over my head before I actually started to try it. So, re-reading the past couple months would probably do me some good now that I have the real thing in front of me. -edrz

[linux-audio-user] Trying to record audio from line in and additional questions

by Sylvain Robitaille

First the vitals: The computer system is a 400 MHz K6-2 with 512 MB memory, and a Hercules Fortissimo II (Cirrus Logic Soundfusion CS4624 processor) sound card. The OS is Linux-2.4.20 (built up from Slackware-8.0, with kernel patches and package upgrades). I have the following ALSA components installed: alsa-driver-0.9.0rc7, alsa-oss-0.9.0rc1, alsa-utils-0.9.0rc7, alsa-lib-0.9.0rc7, alsa-tools-0.9.0rc7. The kernel is mostly monolithic, with the following options (abridged to include only those I know are relevant; if folks want the complete listing, I can easily provide it): CONFIG_EXPERIMENTAL=y CONFIG_MODULES=y CONFIG_MODVERSIONS=y CONFIG_KMOD=y CONFIG_LOLAT=y CONFIG_LOLAT_SYSCTL=y CONFIG_RTC=y CONFIG_SOUND=y ALSA is the only component that I have modularized (only because I don't have the impression it can easily be just built-in, actually), and the following modules are loaded: Module Size Used by snd-mixer-oss 11120 1 (autoclean) snd-cs46xx 58096 1 (autoclean) snd-pcm 50752 0 (autoclean) [snd-cs46xx] snd-timer 9392 0 (autoclean) [snd-pcm] snd-ac97-codec 26912 0 (autoclean) [snd-cs46xx] snd-rawmidi 11808 0 (autoclean) [snd-cs46xx] snd-seq-device 3824 0 (autoclean) [snd-rawmidi] snd 27280 0 (autoclean) [snd-mixer-oss snd-cs46xx snd-pcm snd-timer snd-ac97-codec snd-rawmidi snd-seq-device] I've been using Linux with OSS and a Media-Vision Pro-Audio-Studio-16 soundcard for years, and have basically had very little trouble with that combination. Upgrading to Linux-2.4.x caused the sound output to be rather noisy, so I recently took advantage of the situation to buy a new soundcard, and upgrade to using ALSA (which I've been wanting to do so I can investigate certain rather exciting applications such as Ardour and the new Rosegarden). The applications I've been using for years with OSS, (notably Dap, Mixviews, Aumix, and a few others) all appear to mostly be working fine, presumably through the ALSA OSS emulation. Aumixer now shows some lables (PhoneIn and Video) which don't correspond to any inputs I have on my soundcard, while some others (IGain and Line1) don't appear to have any use, given the way I'm currently using the card (signal from a hardware mixer going to the Line input, and signal from the main, front line output going back to the mixer). I can play back sound files without any problem. In fact I've also tried a few new (to me) applications, such as Audacity, ProTux, and (though I'm having problems with it I won't cover here) Ardour, and they too play back sounds quite nicely (the sound is "grainy", though, perhaps I need to investigate the Low-Latency issues more, or increase the size of some buffer somewhere). I can send sound to the computer, and listen to that sound coming back from the computer (adjusting the level with the "line" level in Aumix, for example), but if I try to record that sound (in any of the applications I've tried, including all those listed above), with "record enable" selected in Aumix, I get no audio recorded (silent sound file). Also, I find it interesting to note that I can record-enable only one input source at a time (contrary to my old Media-Vision card). I'm assuming that's a function of the hardware, though and can't be fixed in software? Finally, we get to my questions: - Can someone point me in the right direction(s) to find a solution to this, so I can record audio (preferably from numerous sources) into my computer? I'll be perfectly happy with pointers to documentation (though I expect to get at least some to documentation I've already read, because I think I've repeatedly gone through all the documentation I already found myself), and suggestions to upgrade certain components. - I've tried to start Jackd at system boot, with the following command added to my rc.local file: /local/bin/jackd -d alsa -d cs46xx -p 512 & Jackd fails to start at that point (I'm afraid I haven't noted the exact error message, but I can make a point of doing so next time I reboot the system), but it does start when run manually from a root shell. Does anyone have any idea why jackd might not start at boot time, (perhaps the ALSA modules aren't loaded yet at that time)? If I understand my boot sequence properly, kernel modules are setup (via "depmod -a") before rc.local is run, so the modules may not be loaded, but they should by that point be loadable (they load automatically by the kernel in regular use). - Is it possible to build ALSA into the kernel? - on a slightly unrelated point, my new soundcard has a built-in synthesizer with at least some features I'd like to explore. Though I know this won't replace any of my hardware synths (or some of the software synths I've begun to play with), I'd like to play around with some of its built-in sounds, and probably use it (at least until I get something better) as my "preset playback" device, controlled from an external MIDI controller. Does anyone have suggestions for how I might go about that? (again, simple pointers to existing documentation would be more than appreciated). In case people are wondering about my specific intended application, I'd like to use a Roland Octapad to trigger percussion sounds from the soundcard's built-in synth. Thanks in advance for any pointers people can provide.... -- ---------------------------------------------------------------------- Sylvain Robitaille syl(a)alcor.concordia.ca Major in Electroacoustic Studies Concordia University Faculty of Fine Arts / Music Department Montreal, Quebec, Canada ----------------------------------------------------------------------

[linux-audio-user] Mandrake 9.1 kernel problem

by Daniel James

Anyone else had problems installing Mandrake 9.1, like the installer not being able to see the CD-ROM it was just loaded into memory from, with lots of DriveReady SeekComplete errors in the console? I've seen this on one machine, but not another. Does anyone know if the 9.1 multimedia kernel includes this patch? http://lists.insecure.org/lists/linux-kernel/2003/Feb/1085.html I wish Mandrake hadn't shipped with a pre-release kernel. Cheers Daniel

[linux-audio-user] [OT] any Xemacs users here ?

by Dave Phillips

Greetings: I'd like to start learning more about emacs, and the Xemacs package has been recommended. I've installed it without problems, but I have some questions for an experienced user. Can anyone on this list help out ? I'm especially interested in using it with Common Music and Csound.

[linux-audio-user] Capture with DIGI9636 Hammerfall Light and playback with PCI 128

by Martin Buechler

Hi, I am able to record using alsa/jackd/ardour with the analog input from an AEB/4-I and plain pcm.rme9652 after tweaking /etc/asound.state by hand for getting the internal input from the AEB working. jackd/ardour works also very well with the PCI 128 only, even at period size 64. Now, I want to record with the RME and having analog playback through the PCI 128. Is this possible? If yes, how to setup .asoundrc? I have been trying many combinations of multi and ttable settings, but honestly, I do not fully understand the syntax and semantics of alsa configurations. I am using kernel and alsa-0.9.0 from a recent PlanetCCRMA distribution, which is really a piece of gold. BTW, after fumbling around with my own kernel patching, I ended always with a complete freeze of ardour, when running jackd in realtime mode. Here is, what aplay says: [root@ardour root]# aplay -l card 0: AudioPCI [Ensoniq AudioPCI], device 0: ES1371/1 [ES1371 DAC2/ADC] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: AudioPCI [Ensoniq AudioPCI], device 1: ES1371/2 [ES1371 DAC1] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: 15 [RME Digi9636 (Rev 1.5)], device 0: RME Digi9636 (Rev 1.5) [RME Digi9636 (Rev 1.5)] Subdevices: 1/1 Subdevice #0: subdevice #0 [root@ardour root]# aplay -v -D hw:1,0 /usr/share/tuxracer/sounds/tux_on_rock1.wav Playing WAVE '/usr/share/tuxracer/sounds/tux_on_rock1.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo aplay: set_params:789: Access type not available Pretty strange, since ardour does not complain, when trying to playback with the RME. Someone stated, that ardour ist writing directly to the hardware, and seems to have no problem, when there's nothing connected to the cards digital outputs. I also don't dare trying to understand, why there is one capture/playback device in /proc/card1/dev for the RME, while ardour reports 18. Since I do not want to purchase another AEB/4-O analog output box, I would really like to know, how I could use my cheapo SoundBlaster. Thanks for your help Martin

[linux-audio-user] xruns vs. disk activity

by rob fell

Hello all I'm trying to get a gentoo based audio box (primarily Ardour) off the ground. Despite my best efforts, I can't eliminate xruns to a level I could live with (10ms+ xruns every 2 minutes on average seems excessive - esp. with stereo @ 44k1). There's some captured data at the very end of this mail. My observations are made using; jackd -v -R -d... -r 44100 -p 128 2>&1 | tee jacklog (i.e. stereo SB16 @44k1) and ardour, session open but not actively playing I'll present my questions before wandering off into a tedious list (apologies for length) of stuff I've already done. Would anyone care to offer an opinion on these questions; 1. Am I expecting too much? Either from my hardware, or the current state of Linux. 2. Is there a vital piece of config that I've totally overlooked? 3. Is there a better way to measure this to home in on the source of the problem? 4. Are the xruns incidental to the disk activity - is this all a symptom of something else? 5. Insert any other question I should be asking here. Thanks in advance for any help/advice offered, I've run out of ideas. Ta R The (abridged) story so far...

[linux-audio-user] mplayer audio-out weirdness

by Dave Phillips

Greetings: Recently I added a DVD drive to my system. My aging RH 7.2 recognized the drive with no trouble, and after I linked /dev/cdrom1 to /dev/dvd MPlayer handled a DVD with not much trouble. Video performance was sluggish though, and worse, I had no audio. So I dug into the MPlayer docs (they're good!) and discovered lots about improving the video performance, but I still couldn't get a peep out of the movies. The drive's analog audio output is connected to the second card (a PCI128) in my machine, yet no matter what I did with the mixer I got no sound. The card output was routed out to a Bose sound system. Here's where the weirdness starts: While fiddling around with things I discovered that I did in fact have audio. It's coming out of my SBLive, not my PCI128 ! Now how does that happen ?? The drive is physically connected to the PCI128, *not* the SBLive, yet the audio is indeed coming from the SBLive. Can someone explain how this is possible ? Do the cards share a codec, and does that matter ? Is DVD audio handled differently than CD audio ? I'm very happy with my new drive and with MPlayer, and I'm glad to have good sound, but what the hey ?! Btw, MPlayer rocks, even under my "adverse" conditions, i.e., I compiled it with GCC 2.96 and am using an nVidia GForce2 video card. Ha, it all works great !

[linux-audio-user] Buzz works with wine!!!

Hi linux-audio-users subscribers, Today I have succesfully used buzz with the latest version of wine. If you don't know it, buzz (www.buzzxp.com) is a very well thought combination of a tracker plus a modular synth, and it's freeware (but I think there are only binaries for windows). It has also a good community behind and a lot of machines/modules/patches available. It appears to work well and sounds very good... under wine (latest version on RedHat 8.0 + PlanetCCRMA) Just FYI, I don't remember discussing buzz on this list and you can also tell me that's a bit OT, but you know... I can't resist ;-) (sorry 4 my english) Bye -- .-----------------------. | Emiliano Grilli | | emillo(a)libero.it | | Linux user #209089 | | http://www.emillo.net | '-----------------------'
