Re: [linux-audio-user] Music CD Data Base

by Martin McCormick

My thanks to all. Cdda2wav appears to be the solution but, of course, there is one more problem. The man page and the help output clearly state: -J] [-L cddbp-mode] [-H] [-g] [-l buffers] [-D cd-device] If I put a -L anything anywhere in that command, it is instant failure: # cdda2wav -D0,0,0 -J -L cddb-mode cdda2wav: Bad Option: -L. use 'cdda2wav -help' to get more information. Hmm. That's what told me to do that.:-) Actually,I have tried -L and -L cddbpmode and several other creative things that one does in one of these syntax quandaries, all to no avail. Where are the examples when you really need them? If I don't put anything in the command with -L flags, cdda2wav appears to work just fine so the -L parameter is what is killing it. I once ran it without the -J flag and it created an .inf file containing headers for title, artist, etc but every line was blank after its header. The system is connected to a working network and all other network applications work. Thanks for any more ideas.

[linux-audio-user] how enabling non-audio (AC3, DTS, MP3) S/PDIF out at ALSA?

by Francisco Fraga

Hi everybody, I would like to know how I could enable the use of non-audio (AC3, DTS, MP3) S/PDIF out at the ALSA context, in a set-top-box with the ALC650 AC'97 chipset, without having to re-compile the Linux kernel. In the linux-2.6.13 kernel, in line 1733 of the the source code "sound/pci/ac97/ac97_patch.c", there is a function: "patch_alc650(ac97_t * ac97)". In this funcion, several ALC650 registers are read and written. I know that, for enabling non-audio (AC3, DTS, MP3) S/PDIF out in an AC'97 chipset, I have to put a "1" at the 2nd LSB bit of the MX3A register, and also choose the correct Category Code for the non-audio S/PDIF format (AC3, DTS or MP3). So I have to basic problems to solve: 1. Find out how to create an AC'97 instance (ac97_t * ac97), in order to use the function "void snd_ac97_write_cache(ac97_t *ac97, unsigned short reg, unsigned short value)" for writing in the MX3A register; 2. Find out the correct Category Code for each non-audio S/PDIF format (AC3, DTS or MP3). If someone could help me, I would be very grateful. Best, Francisco

[linux-audio-user] ADAT/FST file system

by Patrick Rotsaert

Hi, Does anybody know if it is possible to mount and read an Alesis ADAT/FST disk in Linux. AFAIK, this is a propriety file system. I read some messages on the net that Alesis did not release the specs of their file system, but those messages dated from 2001. Maybe there have been changes since then...

[linux-audio-user] Re: best distro for making music

by Brian Dunn

>GENTOO. Man. Perhaps it's just me, but it took me months to get Gentoo up and >running, with help from a couple of folks posting to this thread. I admit it >wasn;t months continually. I got a bit frustrated, and left it partially >installed on the drive, going back to it from time to time, as it wasn't >going to beat me. Now it's working just fine, music apps and all. Nigel Henery: Yah, that's where i'm at. It's nigh on finals week and i'm procrastinating in my studies to make time to wrestle with gentoo video drivers ( i845G, no high rez and no /dev/agpgart, currently seeking help as Higgaion in the gentoo forums, if anyone has overcome these insues before and would like to help :-) ). So i was really just wondering if gentoo has ever successfully been used as a low-latency audio system, to determine weather i should toss in the gloves, as i'm feeling rather defeated. But i can't think of anything worth doing with XP on the 50 Gigs i stole from it's drive for gentoo, so I suppose i'll let it simmer and just try not to think about it 'til the semester is over. thanks to everyone who replied. I'm thinking seriously about replacing that Mandrivia with either ubunto or planet ccrma so i can still use my computer for some fun in the gentoo-interum of consernation... because mandrivia 2006 totaly wacked out my urpmi (the dependency resolver for rpms in mdk) and now it fusses about md5 keys, and can't resolve it's own dependencies, and i told it to just to do it anyways.. OOPS. just to be fair, I've got mdk 10.1 on this here laptop now, and it's been rather stable and useful. So an other lesson i learned from trial and error and y'alls replies "if it ain't broke..." Gratefull, Brian

[linux-audio-user] RE: How to get good vocal sound

by olivier

using an equalizer, could be very helpful too ... for me equaliser + reverb is a very good starting for voices, if you sing hard, the compressor is good, it's easier to use a compressor than playing with the distance and orientation of the micro, even if someones say that's better to don't use any compressor for recording, see yourself ;-) ... ___________________________________________________________________________ Appel audio GRATUIT partout dans le monde avec le nouveau Yahoo!

[linux-audio-user] Problems with MIDIsport 2x2

by Peter Clarke

Dear all, Having just updated my Gentoo kernel from 2.6.11 to 2.6.13 (trying to get my Novation Speedio to work - that's still WIP), I can't get my MIDIsport 2x2 to work any more. Under 2.6.11, it worked easily - I just had to fetch midisport_firmware-0.5.tar.bz2 from Sourceforge, and follow the instructions in the readme file there, which showed me how to set up the firmware loader. But I can't get this to work any longer. I can manually upload the firmware to the MIDIsport using this command: fxload -D /proc/bus/usb/XXX/YYY -I MidiSport2x2.ihx The MIDIsport then flashes its lights and changes its ID and bus address ("renumerates", in the wonderful jargon), but doesn't pick up its driver - here's the relevant section from /proc/bus/usb/devices: T: Bus=03 Lev=01 Prnt=01 Port=01 Cnt=02 Dev#= 14 Spd=12 MxCh= 0 D: Ver= 1.00 Cls=00(>ifc ) Sub=00 Prot=00 MxPS=64 #Cfgs= 1 P: Vendor=0763 ProdID=1002 Rev= 1.21 C:* #Ifs= 1 Cfg#= 1 Atr=a0 MxPwr= 0mA I: If#= 0 Alt= 0 #EPs= 5 Cls=ff(vend.) Sub=00 Prot=00 Driver=(none) E: Ad=81(I) Atr=03(Int.) MxPS= 32 Ivl=1ms E: Ad=82(I) Atr=02(Bulk) MxPS= 32 Ivl=0ms E: Ad=02(O) Atr=02(Bulk) MxPS= 32 Ivl=0ms E: Ad=84(I) Atr=02(Bulk) MxPS= 32 Ivl=0ms E: Ad=04(O) Atr=02(Bulk) MxPS= 32 Ivl=0ms I have put an entry in /etc/hotplug/usb.usermap, pointing to the script (midisport_fw) that's supposed to load the firmware, but no messages appear in the log, suggesting that the script is not getting run. What's going wrong? Why is this not working now, when it was childsplay before? Any help appreciated, Peter C

[linux-audio-user] Which Windows XP File System is Readable by Linux?

by The Other

Hello All who dual-boot Windows XP and Linux, I had to break down and order an OEM disk of Windows XP Professional w/SP2 to be able to run the upgrades to my legacy Windows audio software. I've always gone with Fat16 as the Windows file system so I could read the Windows partition in Linux and exchange files between the two OSes. I know the Windows NT file system was not read/writeable by Linux. So what file system should I install Windows XP with to be able to read and write to it with Linux? Also, is Windows XP going to grab an entire disk for install? Or will it play nice and install only in usable partitions that I set up for it? Thank you, Stephen.
