[linux-audio-user] Clicking noises - how to get rid of?

by Pauline Powledge

Greetings, I am trying to convert some old cassette music to audio CD format. I'm very new to Linux audio, mixers, and so forth, and have some newbie-type questions to ask. I'm running the 2.2.14 kernel with the ALSA drivers, version 5.12a, es1968 module, with an es 1978S soundcard. The problem I have is that I get a loud, persistent, evenly-spaced clicking sound in my input. My mixer is set up with 100% volume, unmuted, and captured on the MIC input, and 20% volume, unmuted, on the Input Gain. Everything else is muted. I have tried running ecasound with "-r -z:nointbuf", but that doesn't seem to help. The dropouts are so consistent -- almost like a metronome -- that I'm not inclined to think this is a latency issue, so I doubt patching the kernel will work. I do my recording with X Windows off and my 802.11B card out. Does anyone have any suggestions about what I ought to try next? When I searched the archive, I saw mention of a problem of persistent clicking with another soundcard that was solved by going from a 2.2 kernel to a 2.4 kernel. Is that a known issue with other soundcards too? Thanks in advance for any clues, Polly

[linux-audio-user] metronome apps

by Dave Phillips

Greetings: Yesterday I wanted to practice with a metronome, so I decided to download one of the listings from the Linux Soundapps pages. Alas, I got no joy: 1. cmetronome's server is unavailable 2. gTick wants to use /dev/sequencer and isn't working for me with ALSA 0.9.0beta10 3. gMetronome is a visual-only metronome and I need sound So I went looking for something else. I found Metronome on SourceForge, but its based on gTick and suffers the same poor output. I also found DiffM, a Java-based metronome that is said to work under Linux, but the available package only works with MacOS. So I still don't have a metronome, and I don't feel like compiling Ardour just to use it as a practice amenity. So, does anyone have a lead to a working software metronome for Linux ? Does anyone have the sources to cmetronome ? Or is anyone interested in writing a simple metronome application ? Back to the hack...

[linux-audio-user] chebstortion in swh-plugins: How *should* it sound?

by Frank Barknecht

Hi, I played a bit with chebdistortion from the SWH set, and I'm wondering, if what I get is the intended result. I doesn't sound like an effect useful for anything to my ears, but I might have a broken version or something. I made an short example at http://footils.org/snd/cheb.ogg with a clean signal, then the chebdistortion kicking in. Is it intent this way? ciao -- Frank Barknecht _ ______footils.org__

[linux-audio-user] CD covers & booklets

by Howard Sanner

I've been trying to use Kover 0.8.4 to create CD tray cards, and, more importantly, inserts. This is the latest version of Kover I could find that does not require KDE 3.0. I'm using 2.2.1 under Mandrake 8.1. The problem I haven't been able to work around is creating the INSIDE of a CD booklet, i.e., pages 2-3. I can get it to put the title on the RH panel and a contents list or whatever I want on the LH panel. However, I can't start on the LH panel with the inside of the booklet and have the text wrap around to the RH panel. Does anyone have ideas? Is there a better program out there for doing this? FWIW, none of this stuff can be downloaded from an Internet database; it's all recordings of live opera performances. Thanks for all suggestions. I realize this is not the main emphasis of the list, so please feel free to reply privately. Howard Sanner flagstad(a)mindspring.com

[linux-audio-user] Advanced Linux Sound(ALSA), PPC, M-audio Duo

by John M Phillips

I am trying to user USB-AUDIO product with a TI laptop for a portable digital recorder. I have followed the instructions at http://www.alsa-project.org/alsa-doc/doc-php/template.php3 ?company=Midiman&card=USB+Audio+Duo&chip=Cypress+AN2131XX&module=usb-audio The compiles for building alsa-driver-0.9.0rc6, alsa-lib-0.9.0rc6, and alsa-utils-0.9.0rc6 went smoothly. The utility snddevices ran with no errors. When running the commad alsamixer, I get the error message "No mixer elems found." Proc/asound appear to have the correct entries dr-xr-xr-x 4 root root 0 Dec 7 16:55 card0 -r--r--r-- 1 root root 0 Dec 7 16:55 cards dr-xr-xr-x 2 root root 0 Dec 7 16:55 dev -r--r--r-- 1 root root 0 Dec 7 16:55 devices lrwxrwxrwx 1 root root 0 Dec 7 16:55 MidimanDuo -> card0 dr-xr-xr-x 2 root root 0 Dec 7 16:55 oss -r--r--r-- 1 root root 0 Dec 7 16:55 pcm dr-xr-xr-x 2 root root 0 Dec 7 16:55 seq -r--r--r-- 1 root root 0 Dec 7 16:55 timers -r--r--r-- 1 root root 0 Dec 7 16:55 version With Proc/asound/card0 having -r--r--r-- 1 root root 0 Dec 7 17:00 id -rw-r--r-- 1 root root 0 Dec 7 17:00 oss_mixer dr-xr-xr-x 3 root root 0 Dec 7 17:00 pcm0c dr-xr-xr-x 3 root root 0 Dec 7 17:00 pcm0p -rw-r--r-- 1 root root 0 Dec 7 17:00 stream0 I found the contributed utility qinit and it runs correctly with the hw name = "hw:0,0". With the "dmasound_pmac" module, dd if=/dev/dsp of=/tmp/sound.out bs=1024 count=1 would produce a file filled with unsigned bytes. The rest of the day was spent trashing about in config files to no effect. Questions: Should alsamixer work with the M-Audio Duo? After enabling with qinit should dd dump data? Any help, or fellow travellers would be appreciated. John Phillips

[linux-audio-user] Re: Audio Help...

by Patrick Shirkey

I have forwareded this on to LAU also. From reading your description (nicely worded too, have you considered writing docs?) It seems like you are mising something either very simple when trying to record from JACKed apps or your driver is not working correctly. Have you tried doing the basic arecord test? Set the capture channel with alsamixer then arecord -f cd -D hw:0,0 -d 10 somefile.wav This should record a cd quality stereo track from the first channel on your first sound device. If that doesn't work then none of the other apps could be expected to either. Personally I still use arecord for recording and edit with other apps once I have file to work with.

[linux-audio-user] Italian LinuxDay Slides

by Emiliano Grilli

Hello everybody, I did a small presentation about the state of Linux audio & music apps on 23rd of November, for the Italian LinuxDay promoted by the Italian Linux Society. I was asked for by some members of FerraraLUG (Ferrara Linux User Group), and now they have put some material on the web. It's in Italian, but if you want to take a look, or reuse the slides... The slides: http://linuxday.ferrara.linux.it/files/linuxday2002-grilli.sxi The audio stream (ogg format): http://linuxday.ferrara.linux.it/audio/32kbps/emilio.ogg (11MB) I had only 45 minutes, so I'm sorry for any software that I left out. I hope to have done a good advocacy for Linux audio for the audience.

[linux-audio-user] So confused, need some good documents about sound in linux!

by Eric Robert

Hi all, Does anybody know where i can get some good/clear/concise explanations about how sounds works under linux? I'm a programmer and a musician myself. I'm so confused between midi, alsa, oss, oss emulation, arts, sound servers artsd, esd, etc...etc... midi ports "a la alsa" or "a la oss" /dev/midiXXX /dev/sound /dev/sequencer or 72:0 73:0 or whatever softsynth, hardsynth........................... All this gets me CONFUSED! I want to develop some kind of band-in-a-box-like stuff with TSE3 The app won't need a midi card (i want to use a softsynth) But first I want to have a clear, global, vision of sound architecture on linux (if not so much precise) I've abandoned window$ years ago and the only thing i really miss is band in a box and i don't want to fall back into microsoft! But i must admit i can't find a unique place that explains the way sound works in linux. I find loads of stuff but can't have a satisfactory global vision of the whole stuff. Has anybody written somewhere a real digest i could use as good starting point? For instance, what REALLY makes the difference between alsa and oss and arts? What are midi ports in each of those architecture? How to adress them? How to to build something for ANY sound architecture? Things about sound deamonds also (what are they for, and how to use them)? Well have been working too hard today , i think my brain is about to burst out ;-) I think sound programming under linux is very complicated because of the different architectures. But developing sound apps like you guys do is a necessary step to convince people to use linux! Maybe my goal is too hard for me but anyway i want to give it a try... But what a MESS!! So any hint on where i can get a thorough, clear, concise explanation of the whole stuff is welcome! Thanks

Debian's alsa-source package has a config file named /etc/alsa/alsa-source.conf. Debconf should have prompted you for the name(s) of your card(s) when you installed this package. If that wasn't done, you can edit that file to define something like this: ALSA_CARDS="ice1712, rme9652, via82xx" Or, you can run (as root): dpkg-reconfigure alsa-source and select the ice1712 driver. -- Jack O'Quin Austin, Texas, USA
