[linux-audio-user] Re: [PlanetCCRMA] alsa-lib 1.04 FC1

by Dave Phillips

Greetings: I'm trying to figure out how to write a grub.conf that will allow a choice between booting into Planet C's RH 8 or RH 9. Here's what I know about the drive structure: For RH8: /dev/hda1 /boot /dev/hda2 / /dev/hda3 /swap For RH9: /dev/hda5 /boot /dev/hda6 / /dev/hda7 /swap A single drive has been partitioned to accommodate both systems. The RH8 install was the first installation, and in the process of installing RH9 grub was rewritten for it (and not for the RH8 partition). So, how do I indicate the choices ? Here's what I'm thinking about for an edited grub.conf : default=0 timeout=10 splashimage=(hd0,4)/grub/splash.xpm.gz ### RH9 title Red Hat Linux (2.4.26-1.ll.rh90.ccrma) root (hd0,4) kernel /vmlinuz-2.4.26-1.ll.rh90.ccrma ro root=LABEL=/1 hdc=ide-scsi initrd /initrd-2.4.26-1.ll.rh90.ccrma.img ### RH8 title Red Hat Linux (2.4.19-1.ll) root (hd0,0) kernel /vmlinuz-2.4.19-1.ll ro root=LABEL=/ hdc=ide-scsi initrd /initrd-2.4.19-1.ll.img Is this kosher ? What will happen if it's incorrect, and what should I do if grub fails ? How do I specify that I want RH8 to be the default system ? Btw, when the RH8 partition is mounted from RH9 (mount /dev/hda1 /mnt/rh8) we discovered that /mnt/rh8/etc/grub.conf is a broken link. I'm sorry about the confusion, but I've never edited grub.conf. Best, dp

[linux-audio-user] alsa on hp omnibook 4150 success story

by Jan Weil

Hi, I just wanted to share this success story (kind of), especially with Dave Phillips. When my desktop PC (more precisely: its elitegroup mobo) suddenly ended up in smoke on Thursday [somewhere in the middle of my diploma thesis :-((] I had to revive my old HP Omnibook 4150. This laptop has a "NeoMagic NM256 piece o' crap" (citing Dave[0]) soundchip which I had not been able to use with ALSA up to then. I decided to upgrade the installed Debian version from Woody to Sarge (current testing) and in doing so I decided to give Debian's 2.6.5-1-686 kernel image a try. Of course, alsaconf tried to load the nm256 driver for the NeoMagic chip which failed as expected. As described in [1] I changed /etc/modprobe.d/sound to contain the following lines: ----8<----- options snd-cs4232 port=0x534 cport=0x538 mpu_port=-1 fm_port=0x388 \ irq=5 dma1=1 dma2=0 isapnp=0 alias snd-card-0 snd-cs4232 alias sound-slot-0 snd-cs4232 ----8<----- An 'update-modules' updated /lib/modules/modprobe.conf and suddenly I was able to start ('/etc/init.d/alsasound start') and use ALSA! Alsa-lib is version 1.0.4-1, drivers are version 1.0.4rc2. I'm quite sure I had tried this before with a 2.4 kernel without success. However, I'm really pleased now (apart from the death of my desktop PC). My digital camera (HP photosmart 715) is fully functional via USB using gphoto2 or flphoto. My Netgear Cardbus Ethernet adapter is recognized and automatically configured via DHCP. I still have to find out whether the alsa configuration survives a suspend. Maybe I'll also test jack performance later. How can I find out whether my kernel has capabilities support builtin? cat /proc/sys/kernel/?? Now I'm thinking of buying an external adapter which lets me use my IDE harddisk (the one from the desktop computer) via USB. (Yes, I have a backup, but it's two days old and it's not complete.) Experiences anyone? (Slightly off-topic) I've got to get some sleep now. Cheers, Jan [0]http://eca.cx/lau/2004/04/0494.html [1]http://alsa.opensrc.org/index.php?page=HP+Omnibook+4150

[linux-audio-user] stereo in: which card?

by Jan Stary

Hello, I need to convert my old tapes to digital audio. They are stereo recordings, and I want to keep it stereo. Probably I will need a card which enables me to actually record it as stereo: I mean, my current card (Soundblaster AWE64) has a LineIn, which only seems to record mono. What I would want is a card which would actually have TWO different holes for the left and right channel to record. Would you suggest a particular one? Or is there a card with a stereo LineIn? Which cable will I need to go from the tape player into the card? Thank you JAn

[linux-audio-user] instrument tuner for jack

by John Anderson

I'm looking for something like this http://www.geocities.com/SiliconValley/Hardware/2684/kguitune_page.html that talks JACK. In other words, an instrument tuner that understands overtone tuning as well as equal-temperament tuning. The only ones I've found with google understand either jack or overtones but not both. thanks John

Re: [linux-audio-user] Linux Audio on the IBM ThinkPad R50

by Dan Harper

Hi Anders, I've updated the page with some new tests: http://danharper.org/Linux_on_the_IBM_ThinkPad_R50.html Jack, Ardour and Jamin work fine. I haven't fully put the Hammerfall through any major tests though, but that will come soon. Details on some other aspects also updated. Expect some more updates soon.

[linux-audio-user] wav to mp3 converter

by Jos Laake

Hey y'all, I have a script that I run when I close down my studio that copies all of my random recordings over to the 'Dailies' area on my web site. But all of these snippets are .wav files (mostly from Timemachine & Audacity). I'd like to have the script batch convert all the .wav's to .mp3's before the copy. That way, my musical partners don't have to download a 40MB .wav file to see if they want to work with a snippet. So what I really need is a high quality command line driven wav->mp3 converter that I can set up something like: convertorthang -o=mp3 *.wav and have it just do it... Oh, and not try to do it again if the file already exists. Okay, I'll go Google around, but if anybody's got a good pointer for me, lemme know, eh? ;-) toodles! ~Jos~

[linux-audio-user] XRuns with the Audiophile 24/96 M-Audio

by Remi Bernhard

Hello, I read a lot a great thing about the audiophile 24/96 on the net, and i decided to buy it to get better latency than my old sblive! I just received the audiophile 24/96 and unfortunatly, i have a lot of XRuns with when i run jackd. I already tried the following : - i changed irq (several changes : irq5, then irq 10) - Disable nearly all the inboard harware (serial port, parallel port, usb) - i changed the Pci port - i tried to run jackd as root - i even tried to raise buffer at big values : 512, 1024, and even there i have some (1 or 2) xruns - i'm now trying with kernel 2.6.6 to see if things are better Hardware : MSI K7N2Delta MB Athlon 2400 Nvidia Geforce 4mmx Audiophile 24/96 M-Audio Sofware : Debian/Testing Kernel 2.6.5 Alsa 1.0.4rc2 Realtime-Lsm 0.1.0 Do you have ideas, before i return the card to the shop ? Regards, Rémi Bernhard.

Very nice. I like the fact that you didn't sugar-coat it. There can be problems but it's usually worth the effort.

by Ivica Ico Bukvic

Ok, so the rough version of the paper (following initial 10-hour revisions that converted my brain into a gray mush) is now available in the PDF format from my website. If you are interested in providing some feedback as to how I can make the paper even better, please let me know asap as I only have another day or so before I need to turn-in the paper. Also please note that the paper will be available in the ICMC proceedings as a short version that lacks chapters 7 and 9 due to space constraints. The full paper will be available online-only. The url to the PDF is as follows: http://meowing.ccm.uc.edu/~ico/temp_online.pdf Any comments and/or suggestions are welcome and appreciated (although I honestly cannot guarantee that all of them will make it into final revision due to aforementioned deadline). Time to hit the sack... Best wishes, Ivica Ico Bukvic, composer & multimedia sculptor http://meowing.ccm.uc.edu/~ico/
