[linux-audio-user] Fedora and ALSA drivers.

by Richard

Hi all I try to compile ALSA drivers for Fedora and up to now im hitting a brick wall.Any alsa version 0.9.6 to the latest 0.9.7c is not compiling.It all fails. The failures vary and mileage vary. It all configures right but build fails. Anyone on the list succeeded with building the drivers on Fedora ? Thanks :) Richard

[linux-audio-user] alsa mixer settings timing out

by John Bleichert

Hello All On this workstation here at work I never log out from Monday morning to Friday evening, sometimes longer, but still every morning when I come in I have to run alsamixer to unmute and bring up the volume on my sound card. What can I do to keep alsa from "timing out" like this? This is an intel8x0 chipset that otherwise works fine. Thanks - JB // John Bleichert // syborg(a)earthlink.net

[linux-audio-user] generating soundfonts

by Atte André Jensen

Hi I'm working on some soundfonts in swami, but it's frustrating that there's no sample editing features in there. Basically what I need is simply to removed portions of the sample. This is not possible from within swami, right? Next solution would be to process the samples in some other program, but then it would be nice to be able to setup sample points here that were imported into swami. Is that possible, and if so with which program? Thanks in advance... -- peace, love & harmony Atte http://www.atte.dk

[linux-audio-user] an open source audio website

by Robert Jonsson

Hi people. I don't think it is common knowledge that www.archive.org has an extensive amount of live recordings stored that can be freely listened to! Some great stuff there, only problem is that most stuff is stored as Shorten files. It gives very good sound quality since shorten is a non destructive compression format, but it sure gives my broadband connection a beating! Just go to: http://www.archive.org/audio Just recently I noticed that they have a added subsection called "Open Source Audio" which seems to be open for any kind of recording. Looks like this could become a great place for sharing music / sounds. /Robert

[linux-audio-user] recording issue? /dev/dsp

by aguerrier

hello >I am trying to record from line in and I can hear the source > through my speakers, but I don't get any waveform in sweep. > I'm using /dev/dsp as my recording device. Any suggestions > would be appreciated thanks. > I have encoutered this problem, as well, using audacity. The quote is from another list dated early september 03. Please help me and other newbies. Maybe there is a faq which answer this problem, illuminating us to /dev/dsp. I searched a few archives for an answer but I found none. thanks

[linux-audio-user] hex base i/o addresses?

by Aaron Trumm

Hi y'all - I'm having trouble with this one: I need to know the base i/o in hex of my sound card, so I can feed it to Cakewlk which is running in dosemu, but I can't figure out how to find out such a thing - I can't even tell if lspci is telling me any version of it (actually, I need to know the base i/o of the two midi ports on the sound card - of course the card is the HDSP9652 - I don't know if that would be different, I guess not but I don't know for sure) well thanks in advance! -- -------------- Aaron Trumm NQuit www.nquit.com --------------

[linux-audio-user] 2 questions ree: via vt8233

by Matt Price

Hi, running debian sid with a 2.4.18 kernel and alsa 0.9.5, I think. Folks on this list and alsa-user helped me get alsa working with my onboard sound, via vt8233, about a year ago. It works ok, but I've got 1 problem and one question. PROBLEM: every once in a while -- not often -- sound will hang and bring the whole system down; this happens with xmms, alsaplayer, and zinf, so I don't think it's strictly the playback software's fault. usually this isn't a catastrophe, since this is a workstation, not a heavy-duty server, but I'd like it not to happen. Anyone see this behaviour before, or know how I should try to diagnose it? QUESTION: My sound card has three analog outs (green, blue, pink). I gues sthese are for a 5.1 surround sound system or something, but I'd like to try to have one stereo out go to my cheapo speakers, and one go to my headphones. Unfortunately I'm unable to get a signal out of anything other than the pink out. The others just give static and wierd stuff, even with all the outputs turned up in alsamixer. Anyone know if it's possible to set this up the way I want? Even general hints abbout how 5.1 systems work would probably be really helpful. thanks loads, matt

Re: [linux-audio-user] Fedora and ALSA drivers.

by "horsh

Richard, For me it looks like your kernel has ALSA included into source tree already. It is only a guess -- I dont have a lny linux in hands right now but you can check it with something like: find /usr/src/linux/ | xargs grep -sqi alsa && echo yes I have ALSA in kernel NB: i haven't try this but should work horsh ==================8<=========================== Hallo, Richard hat gesagt: // Richard wrote: > This only 2 examples. > > gcc-3.3.1-6 > kernel-2.4.22-1.2097.nptl > kernel-source to match > > gcc -D__KERNEL__ -DMODULE=1 -I/home/ric/alsa-driver-0.9.7c/include -I/lib/modules/2.4.22-1.2097.nptl/build/include -O2 -mpreferred-stack-boundary=2 -march=athlon -DLINUX -Wall -Wstrict-prototypes -fomit-frame-pointer -Wno-trigraphs -O2 -fno-strict-aliasing -fno-common -pipe -DALSA_BUILD -DEXPORT_SYMTAB -c hwdep.c > In file included from /home/ric/alsa-driver-0.9.7c/include/sound/driver.h:42, > from hwdep.c:22: > /home/ric/alsa-driver-0.9.7c/include/adriver.h:134: error: redefinition of `PDE'/lib/modules/2.4.22-1.2097.nptl/build/include/linux/proc_fs.h:17: error: `PDE' previously defined here > make[1]: *** [hwdep.o] Error 1 > make[1]: Leaving directory `/home/ric/alsa-driver-0.9.7c/acore' > ... > At some point i been told that the drivers needed be fixed to compile in > fedora.so. well if you can make out something out of this.. ill appreciate Well, this is a bit strange. I'm guessing a bit now: The offending lines in your example result from adriver.h defining things for some kernel versions, including kernel 2.4.22. For example the error regarding PDE: /home/ric/alsa-driver-0.9.7c/include/adriver.h:134: error: redefinition of `PDE '/lib/modules/2.4.22-1.2097.nptl/build/include/linux/proc_fs.h:17: error: `PDE' previously defined here This means, that somewhere in "include/linux/proc_fs.h" the name PDE is already defined. In adriver.h ALSA tries to define it on its own like this: #if LINUX_VERSION_CODE < KERNEL_VERSION(2, 5, 4) #include <linux/fs.h> static inline struct proc_dir_entry *PDE(const struct inode *inode) { ... #endif The strange thing is, that in my rather vanilla version of kernel 2.4.22 there is no such thing as PDE in include/linux/*: $ grep PDE /usr/src/linux/include/linux/proc_fs* $ (nothing here) So I suspect, but I can only guess here, that your kernel source has a patch that introduces this PDE thing (I have no idea what it could be used for). I don't know if ALSA could fix that at all. It might be, that if Fedora ships a custom Linux kernel source, they should also provide adapted ALSA-sources. ciao -- Frank Barknecht _ ______footils.org__

[linux-audio-user] How to check if I have midi connection?

by Ketil Thorgersen

Sorry about this extremely naive question, but since this is my first time trying to get linux to be a DAW I stumble onto some problems of course. And my know-how is somewhat limited unfortunately. My staudio c-port (envy 24 based 8 channel card analogue + 2 channel digital from www.staudio.com with built in midi-interface) works as far as audio goes now, but I can't seem to get anything out of the midiports even though it seems to be properly recognized. Alsa Patch bay gives me a: Rawmidi: 0 - Hoontech SoundTrack Audio DSP24 MPU-401 entry at least (actually 2 - one for each midi port), but no matter which I choose in rosegarden or any other app, I get no signal in the displays. How do I find out if it's working, and how do I troubleshoot. If this is well documented somewhere and comprehensible for semidummies, I'd be happy to receive a link! Best regards Ketil
