[linux-audio-user] PlanetCCRMA - RealPlayer -artsd problems

by Dave Phillips

Greetings: I installed RealPlayer on a machine running RH 8.0 and PlanetCCRMA. At first it worked fine, but now it gets the following error on startup under KDE : SNDCTL_DSP_SETFMT failed Cannot allocate memory Anyone know how to resolve the problem ? Is artsd the culprit here ? RealPlayer also complains that another application has the sound device. Weird: this machine has a SBLive installed with the PlanetC ALSA drivers, I don't understand why RealPlayer complains about not being able to access the device. So, how do I check to see who's hogging the resources ?

[linux-audio-user] Audio file format

by Robert Epprecht

I have found a CD with audio files and would like to know what format they are. (I know very little about different audio formats, sorry.) The label on the CD says they are MP3, but the files have names like 1.wav 2.wav mp3blaster 1.wav Bad sound file format. cp 1.wav /tmp/1.mp3 mp3blaster /tmp/1.mp3 Sound device control error. play 1.wav playing 1.wav ('play' plays the file and considering it's duration it is much too long to be a normal .wav file, IMHO) file 1.wav 1.wav: RIFF (little-endian) data, WAVE audio, Microsoft ADPCM, mono 44100 Hz I thought WAVE was a format without compression? The duration of the files (when played by 'play') shows that this is not possible. So what is it? BTW: The file (loaded like a text file in emacs ;-) starts with RIFFBä^BWAVEfmt 2 (where ^B is *one* byte) Thank you for sharing your knowledge, Robert

[linux-audio-user] Multiple soundcards

by Bryan Koschmann - GKT

Hello, I'm looking at (for now) utilizing the SB 128PCI's I have laying around and doing 3 of those for input and 1 SB Live Value for midi and output. Any recommendations against that, or thoughts that an SB 16 PCI would be better? I have access to a few of those as well. As I said in my posts awhile back, I have 2 instrument mics, 1 vocal mic, and a keyboard with midi. The mics are all XLR with 1/4" (transformers?). Will I be needing any preamps/mixer for these? If so any recommendations for something with 3 mic preamps? I apoligize for all the questions. I'm quite new to the audio world and have only ever had real user experience with Soundforge on a win98 box :) I'm looking forward to some hardcore stuff once I learn. Thanks! Bryan

[linux-audio-user] ALSA 0.9.1 on IBM ThinkPad T20

by Greg Reddin

Hey all, I'm sort of a Linux newbie. I've been using Linux pretty much exclusively for a little over a month. I've used and developed on Unix for several years, so much of it is familiar to me. Anyway, I got ALSA up and running fine on my desktop machine, but am having problems with my laptop. I searched the web for days and can't seem to find consistent information, so I wonder if you guys could help. My laptop is an IBM Thinkpad T20 with a "Cirrus Logic CS-4614/22/24 CrystalClear SoundFusion Audio Accelerator" soundcard. I'm running a fairly "vanilla" installation of RedHat 8.0, meaning I didn't reconfigure the kernel or anything like that. The kernel version is 2.4.18-14. The OSS driver for cs46xx was installed, and I believe the sound test worked during installation. But since then, audio has not worked at all. XMMS will play,and you can see the meters popping, but no sound comes out of the speakers or headphones. I downloaded the ALSA 0.9.1 tarballs and ran through the installations. The first problem I ran into was unresolved symbols due to symbol versioning in the kernel. I fixed that by adding the following to the alsa-driver Makefile: ifdef CONFIG_MODVERSIONS CPPFLAGS += -include /usr/src/linux-2.4.18-14/include/linux/modversions.h endif So, I did a make clean, reran the ./configure, make, make install, ./snddevices, and installed alsa-lib and alsa-util. At some point I had to rmmod the cs46xx OSS driver because it complained that it was in use. I also chmod'ed the /dev files as the doc suggested. I used gnome-alsamixer to unmute the channels and set levels. At first alsaplayer would play a file (.wav or .mp3) and the meters would show activity, but no sound would be present. Now, when I try to run alsaplayer, play, or xmms I get an error message that says "Cannot open device: /dev/dsp". So has anyone gotten ALSA 0.9.1 to work on this kernel? Should I use a different ALSA package or a different kernel? Any suggestions would be greatly appreciated. Thanks, Greg Reddin __________________________________________________ Do you Yahoo!? Yahoo!

[linux-audio-user] Helpful info for ppl trying to install RH 8.0 (for CCRMA stuff) using Intel 845G chipset (this could be a valuable documentation for others)

by Ivica Bukvic

Hi all, I saw a couple posts on this matter on other lists namely from people who are trying to make multimedia Linux boxes using CCRMA packages and RH 8.0. The issue at hand is that many of the newer machines with cheapo embedded video cards use Intel 845G chipset which is unsupported by RH 8.0's XFree 4.2. However, XFree 4.3 does support it and so the following needs to be done (assumption is that you have a reasonably fast internet connection, otherwise this might prove to be pain -- total d/l amount is approx. 70MB): 1) Install RH 8.0 in command-line mode (graphics mode will most likely fail -- it did on mine, although it might have been partially due to use of an outdated flatscreen monitor that did not allow even the framebuffer mode) 2) Skip XFree config (if you really feel compelled to configure it, do NOT test it, it WILL fail) 3) Upon reboot, using Internet connection, connect to the following ftp in order to retrieve XFree 4.3 version of the x server for the RH 8.0 (you might try the Rawhide mirrors as well but I am not sure whether those will work): ftp://people.redhat.com/mharris/testing/unstable/XFree86 (thanks to Mike Harris from Redhat for making them) 4) Install XFree packages by doing: rpm -Uvh *.rpm --nodeps --force (don't worry it should be ok, at least it was on mine :-) 5) configure up2date 6) run: up2date glibc (you need 2.3.2 for Xfree 4.3, and the one that comes with RH is 2.2.something) 7) Upon finishing installation, run: redhat-config-xfree86 -o /etc/X11/XF86Config (you might need to tinker with the config file, depending on your monitor and other hw) 8) Try starting x server with: startx 9) Now, you should be up and running, but you still need to enable acceleration (since otherwise anything with OpenGL will be simply impossible to use). You need to get the new version of DRI (which reports errors since the kernel module i830.o is ver.1.2 not 1.3 as required by Xfree4.3). So go download new DRI package for 4.3 from here: http://www.xfree86.org/~alanh/linux-drm-4.3.0-kernelsource.tar.gz (big thanks to Leif Delgass for pointing this out) 10) untar the package and make the new module by doing: make -f Makefile.linux 11) install the i830.o file by copying it to the /lib/modules/<kernel-version>/kernel/drivers/char/drm/ (you might wanna backup the old module to something like old-i830.o just in case something screws up) 12) Now reboot the machine and check the /var/log/XFree86.0.log for any DRI errors. You might also wanna run the glxgears or something similar to see if everything is ok. Don't expect much of a fps increase, though (I had 336 fps on the studio's 2.4GHz P4 machine, while with DRI it went up to only 400+ fps). What you will, however, see is the smoother moving the OpenGL window around the desktop and generally better system responsiveness. Now I can even play the Tuxracer at a reasonable framerate. Yay! That's it. Hope someone finds this helpful. Cheers! Ivica Ico Bukvic http://meowing.ccm.uc.edu/~ico

Therefore it would be nice to have a constant y value (I don't see an interesting use for y!). So it would be great to read out that one y-line and produce MIDI notes until Ctrl-C is pressed. I'm more involved into the ALSA side of this problem and absolutely new to sane development. So my question: Is it possible to solve this (read out one line without y movement) in a frontend application? Or do I have to patch the backend part? Is there any developer information available? I've just had a look to some command line frontends, but they don't touch this point (ok, it's possible that I'm blind!). But my impression was: they only handle complete scans, which I don't want to use. Or is there a general problem in the control of scanning devices, if I have this goal ..... because they were not build for this use. Is there a counterpart to "sane_get_parameters()" for setting those parameters, like lines and pixels? Anybody out there, who can give me some hints or who can say: "Forget It!" thanks, martin _______________________________________________ Sane-devel mailing list Sane-devel(a)www.mostang.com http://www.mostang.com/mailman/listinfo/sane-devel ----- End forwarded message ----- -- Ross Vandegrift ross(a)willow.seitz.com A Pope has a Water Cannon.

[linux-audio-user] snd freezes when recording

by Ralf Haller

Hi, when I try to record with snd by selecting record in the file menu, the record window opens but freezes without properly displaying the controls. Recording with other tools like sweep works without any problems. I am using RedHat 8.0 and installed the kernel and alsa drivers from planet ccrma. Any clues? r(a)l.f
