Hallo, well, some of these things run Linux and it has to do with audio signal transportation somehow so I guess this link is not *totally* off topic: http://www.sidetalkin.com/ ;) Also there's one guy with a cool mixing console up his ear! ciao -- Frank Barknecht _ ______footils.org__

[linux-audio-user] Loop points with libsndfile

by Peter Bessman

I should post this to either libsndfile-dev or lad, but I'm already subscribed to lau so I'm gonna test the waters here first. Does anybody know if libsndfile supports sound loop points and playlist data chunks? (Erik, I know you're out there...)

RE: [linux-audio-user] Soundblaster Live w/Live Drive

by Reuben Martin

The .asoundrc setup should have little to do with what multiple io ports show up. When you connect jack to hw:0 any available ports on that device should show up. You would only need features available from .asoundrc if you wanted to use a plug interface of some sort, and those things are dog slow. regards -Reuben -----Original Message----- From: Adam King [mailto:aking@lgh.com.au] Sent: Sat 11/1/2003 7:13 PM To: linux-audio-user(a)music.columbia.edu Cc: Subject: [linux-audio-user] Soundblaster Live w/Live Drive Hi all, I've just purchased a Soundblaster Live Platinum 5.1 w/Live Drive. I've got it all set up and working with the ALSA drivers but I am having trouble with JACK and the .asoundrc file. I want to be able to have multiple in/out ports. Example, I want to be able to use jackEQ and send the master output to speakers, and the monitor output out to headphones. Does anyone have a same .asoundrc file or can give me tips on how to set it up? I've tried reading the ALSA docs but am not having much luck. Thanks, - Adam

[linux-audio-user] Building SpiralSynthModular - undefined libpng references

by Benjamin Flaming

I'm trying to build SpiralSynthModular on a Slackware 9.0 system. Everything seems to go fine until I get: /usr/local/lib/libpng.so: undefined reference to `deflate' /usr/local/lib/libpng.so: undefined reference to `inflate' /usr/local/lib/libpng.so: undefined reference to `inflateInit_' /usr/local/lib/libpng.so: undefined reference to `crc32' /usr/local/lib/libpng.so: undefined reference to `deflateInit2_' /usr/local/lib/libpng.so: undefined reference to `inflateReset' /usr/local/lib/libpng.so: undefined reference to `deflateReset' /usr/local/lib/libpng.so: undefined reference to `inflateEnd' /usr/local/lib/libpng.so: undefined reference to `deflateEnd' collect2: ld returned 1 exit status make: *** [spiralsynthmodular] Error 1 I downloaded, built, and installed the latest version of libpng (including the obligatory download/build/install of the latest zlib), and ran ldconfig, but I still get this message. I've tried building 0.2.0rc2 instead of 0.2.1, but the result is the same. I also tried not using the --enable-jack option when "./configure"ing, with no effect. gcc version is 3.2.2 ld version is 2.13.90.0.18 20030121 Any suggestions? |) |)enji

[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 ----------------------------------------------------------------------

Re: [linux-audio-user] alsa setup debug (was: jackd -d alsa -d hw:0 -p512 / problem to start)

[linux-audio-user] mounting network drives for dummies?

by Mark Knecht

Hi, I've got two Linux boxes, one Gentoo and the other PlanetCCRMA. I need to move about 10GB of data from one to the other. How can I do this? I guess that over Ethernet maybe Samba or NFS might work? I don't know anything about making either of these technologies work, and obviously I don't want to start building kernels or anything like that to get there. Has anyone got a tutorial on how to do this easily. I really don't want to become an IT guy to make this work. If it's too difficult, then I could dig up and add a 1394 adapter to one box and dump it to the other that way. The second machine has 1394 already. I just didn't want to open the box up and mess with cards. Thanks very super much in advance, Mark
