[linux-audio-user] Linux Laptop Sound article published

by Dave Phillips

Greetings: A while ago I polled this group for information and opinions about setting up sound on laptops running Linux. My article has been published, you can find it here: http://linux.oreillynet.com/pub/a/linux/2002/09/19/linuxlaptop.html Please note that it is rather model-centric, charting my experiences with the HP Omnibook 4150, but hopefully it will inspire other laptop owners who may have difficulty setting up a sound system on their machines. Again, my thanks to all who responded and shared their own experiences with me. As an aside, I must say I've been rather lucky with my 4150, and I had relatively few problems. Someday someone wil have to rate a variety of laptops by their ease of sound setup for Linux. It's evident that some machines and/or chipsets are just not very Linux-friendly, and that information could be very useful for a user looking for a laptop to run Linux audio apps.

[linux-audio-user] (no subject)

by Jago Pearce

The Alsa documentation is confusing me massively. I have no problems getting a basic setup sorted but I'm having trouble when trying to do more than one thing at a time. I have 2 soundcards: - via686 onboard (half-duplex hardware. Can only record OR playback, can only playback one thing at a time atm) - ymfpci (should be full-duplex. Can play back more than one thing at a time. Should be able to record whilst playing back) One way or another I need to record whilst playing back and be able to playback from >1 source (i.e. play 2 mp3 files at once). To do this: - How do I go about setting up /dev/dsp1 as well as /dev/dsp? (I have edited /etc/modules.d/alsa and update-modules to no avail. Can I do this with seporate soundcards or just one? (the ymfpci has 2 channels) - How do I get my yamaha to record whilst playing back (full-duplex)? I have followed install instructions and I think it should work Any links or suggestions would be great. I'm finding Alsa incredibly compilcated for me. Perhaps (as the most simple answer) I could have the via686 using standard OSS and the ymfpci using Alsa? ------------------- details to follow:- ------------------- #lsmod snd-pcm-oss 36804 1 snd-mixer-oss 9184 0 [snd-pcm-oss] joydev 6816 0 (unused) input 3424 0 [joydev] snd-opl3-synth 8604 0 (unused) snd-seq-instr 4432 0 [snd-opl3-synth] snd-seq-midi-emul 4560 0 [snd-opl3-synth] snd-seq 37868 0 [snd-opl3-synth snd-seq-instr snd-seq-midi-emul] snd-ainstr-fm 1540 0 [snd-opl3-synth] ppdev 8292 0 (unused) lp 6176 0 (unused) hid 15072 0 (unused) sr_mod 11864 0 (unused) apm 9608 1 uhci 24296 0 (unused) vfat 10780 0 (unused) fat 32056 0 [vfat] parport_pc 13252 1 parport 14208 1 [ppdev lp parport_pc] printer 7488 0 (unused) scanner 8512 0 (unused) NVdriver 1065920 10 ide-scsi 7680 0 eepro100 17456 1 snd-via686 7076 0 snd-ymfpci 41664 1 snd-pcm 56256 0 [snd-pcm-oss snd-via686 snd-ymfpci] snd-ac97-codec 24432 0 [snd-via686 snd-ymfpci] snd-mpu401-uart 2736 0 [snd-via686 snd-ymfpci] snd-rawmidi 12896 0 [snd-mpu401-uart] snd-opl3-lib 5408 0 [snd-opl3-synth snd-ymfpci] snd-timer 10688 0 [snd-seq snd-pcm snd-opl3-lib] snd-hwdep 3712 0 [snd-opl3-lib] snd-seq-device 3936 0 [snd-opl3-synth snd-seq snd-rawmidi snd-opl3-lib] snd 25928 0 [snd-pcm-oss snd-mixer-oss snd-opl3-synth snd-seq-instr snd-seq snd-via686 snd-ymfpci snd-pcm snd-ac97-codec snd-mpu401-uart snd-rawmidi snd-opl3-lib snd-timer snd-hwdep snd-seq-device] # cat /etc/modules.d/alsa # Alsa 0.9.X kernel modules' configuration file. # $Header: /home/cvsroot/gentoo-x86/media-sound/alsa-driver/files/alsa-modules.conf,v 1.3 2002/06/24 18:05:58 agenkin Exp $ # ALSA portion alias char-major-116 snd # OSS/Free portion alias char-major-14 soundcore ## ## IMPORTANT: ## You need to customise this section for your specific sound card(s) ## and then run `update-modules' command. ## Read alsa-driver's INSTALL file in /usr/share/doc for more info. ## ## ALSA portion alias snd-card-0 snd-ymfpci alias snd-card-1 snd-via686 #alias snd-card-2 snd-ymfpci #alias snd-card-3 snd-via686 #alias snd-card-4 snd-ymfpci #alias snd-card-5 snd-via686 #alias snd-card-6 snd-ymfpci #alias snd-card-7 snd-via686 ## OSS/Free portion ## alias sound-slot-0 snd-card-0 ## alias sound-slot-1 snd-card-1 ## # OSS/Free portion - card #1 alias sound-service-0-0 snd-mixer-oss alias sound-service-0-1 snd-seq-oss alias sound-service-0-3 snd-pcm-oss alias sound-service-0-8 snd-seq-oss alias sound-service-0-12 snd-pcm-oss ## OSS/Free portion - card #2 alias sound-service-1-0 snd-mixer-oss alias sound-service-1-8 snd-seq-oss alias sound-service-1-12 snd-pcm-oss #alias /dev/dsp1 snd-pcm-oss? or something? ...? ----- Thank you for your time.

[linux-audio-user] New software synthesizer for Linux (free under GPL v. 2)

by Nasca Paul

Hi, I wrote a software syntesizer for Linux, it is available at http://zynaddsubfx.sourceforge.net/ or http://sourceforge.net/projects/zynaddsubfx/ . It has many features including: polipohony, multi-timbral, microtonal capabilities, 2 synth engines, effects (system and insertion), user interface. I started this project on March 2002 and this is the first relase. I hope that you'll like it. Paul. __________________________________________________ Do you Yahoo!?

[linux-audio-user] [Fwd: Re: [ardour-dev] Ardour, IRQs and xruns]

by Patrick Shirkey

People here who are not on the ardour list should find this interesting and helpful. Mark. I have an Nvidia agp card which uses irq9 and a usb audio card that I can put on 11. Now I ust have to figure out how to tell which USB port is using 11 and which is using 4. Thanks. -- Patrick Shirkey - Boost Hardware Ltd.

[linux-audio-user] programmable dsp box?

by Will Benton

Hey, all. I was just browsing and saw the Soundart Chameleon, which looks like a really cool toy. Unfortunately, the development tools are windows-only. I'm sure that I could run at least some of them under wine/vmware, but I'm not too interested in 1. buying a Windows license to get DLLs that I need to run some program properly under Wine (or at all under vmware), or 2. paying $700 for a hardware device from a company that refuses to support Linux or release the code for their compilers (especially since their business model is explicitly stated as "give away compilers for free, so people will make applications and we can sell chameleons"). My other concern is that I'm going to buy a powerbook soon (probably dual-booting OS X and Linux), so having an open-source toolchain would make it much less painful to switch back and forth between my big computer and my portable. Finally, it's been 7 or 8 years since I've done any software development in a Windows environment, and I don't think I could go back without a lot of pain, now that I'm so used to having the standard Unix tools. (Yeah, I know about cygwin/etc, and I'm not trying to start another Linux/Windows flamefest :-) What other programmable dsp boxes (preferably using the gcc toolchain) are there? I'm interested in something like the Chameleon, a rackmountable box with a DSP engine, LCD, control knobs/buttons and audio and midi ins-and-outs. Obviously, the "rackmountable" requirement is least important, but it would be nice, since there's a lot of cruft on/around my desk in the basement. :-) best, wb -- Will Benton <willb(a)cs.wisc.edu>

Re: [linux-audio-user] strange problems with snd

by Bill Schottstaedt

> Incidentally, now that it's working, is there a way to make the fonts bigger? There are too many ways to do this! I use either the ~/.Xdefaults file with lines like: snd*axisLabelFont: -adobe-times-medium-r-normal-*-18-*-*-*-*-*-*-* snd*helpTextFont: 9x15 or the init file (~/.snd) with similar stuff: (set! (axis-label-font) "-adobe-times-medium-r-normal-*-18-*-*-*-*-*-*-*") (set! (axis-numbers-font) "9x15"))) You can use the same init file with gtk (which has a different font naming convention) -- see grfsnd.html for details.

[linux-audio-user] Help! screenshots please.

by Steve Harris

Hi all, I'm trying to put together some content for the proceedings of the Modular 2002 conference, where I spoke about the state of Linux Audio, but I need decent screenshots for Muse, pd and Noteedit, none of which I know well enough. Ideally screenshots should be <= 1024x768 - 600x400 is ideal. Obviously anyone who provides shots gets mentioned in the acnowledgements. Slighit problem is that I need the shots ASAP, I need to submit the content in the next 2 hours. Cheers, Steve
