hi all!! my name is criscabello and i´m from brasil. please excuse my poor english. at first, i'd like to thank all of you linux audio developers who made it possible for us to work with free plataforms. all of us, brazilians, are very pleased with the result of all your work. let me explain. i work in a government project called "pontos de cultura" (points of culture), and it is based in the distribuition of media stations with free software to some places who are in a state of digital, or social, exclusion at this time (but not much longer, we hope). this project has a national scope, and in the beggining of 2005 will be distribute more than a hundred (100) media kits, with projections of distributing another thousand (1000) in the next two years! last saturday our group had a meeting with our minister of culture, gilberto gil, to showcase some softwares for media production (like ardour, audacity, hydrogen, jack, alsa driver, cinerrela, kino, etc...), and he was totaly convinced about the possibilities of our free software media production kit. He also understood the power of collaboration based work and open source development - this article from wired magazine (http://www.wired.com/wired/archive/12.11/linux.html) says more about the minister. oficialy, gil represents our nation, and his opinion represent all Brazilian's voices! at the end of our meeting, we recorded one of his songs using ardour, gil is a popular singer in brazil (and the world) and this was his first recording using free software. during the session the only thing in my mind was: thank you so much paul davis and all the developer communities! you all can listen to the song (and sample and remix it if you like, it is distributed under a creative commons license) from here: in ogg format: http://banto.hipatia.info/maquina-de-ritmo.ogg in mp3 format: http://www.pirex.com.br/pirexmp3/maquina-de-ritmo.mp3 this e-mail is to tell everyone that this is just the beginning, we have much work to do together (can you imagine the demands from all of these people working with our free platform?). and i'm so glad for this momment. thank you so much. criscabello ps. please foward this message for the developments lists.

[Fwd: Re: [linux-audio-user] Preach it! [was: Re: [linux-audio-user] Re: Behringer etc.]]

by Ruth A. Kramer

Marek, You (and others, you're not alone) would save us (readers) a lot of time if you would try some major trimming of posts to which you respond. The original post I'm concerned with is attached. Here is how I would trim it. If anybody needs more information it is in the previous posts. Well, actually, I wasn't sure specifically what to leave in the original post (the one you replied to) as I wasn't sure exactly what you were responding to. So, I assumed your response was somewhat general and just left the last few paragraphs of the previous post. Trimming, or better, aggressive trimming, helps us all save time. regards, Randy Kramer PS: Copying to the list for the edification of all -- if the shoe fits ...

[linux-audio-user] can't get jack working in SuSE 9.1

by Robert Persson

I am having a lot of trouble getting Jack working under SuSE 9.1 It is very hard to keep track of the problem because the symptoms seem to change every now and then for no reason I can fathom, and because I have had other problems configuring soundcards in the past most (but not all) of which seem to have mysteriously sorted themselves out for no apparent reason. Therefore I will just give you for now a snapshot of the problem in its current (though fairly typical) manifestation for the sake of brevity. First of all you might need to know the following: 1. The problem has occurred with both the kernels I have used, each compiled from different (non-suse) sources. 2. I have 2 soundcards: an on-motherboard i810 and an Audigy 2. Only the Audigy 2 seems to work at the moment, although I would prefer it if both did. In the past various Linux installers have got them mixed up and caused a lot of pain and silence, including suse 9.1. Why suse 9.1 turned round and got it right the second time is completely beyond me. 3. I have been very careful to avoid arts-jack conflicts while troubleshooting. 4. The Agnula DeMuDi live CD got Jack working with the Audigy 2 card and I was able to make silly noises with it and route signals to my heart's content on the very same hardware. This is a variant of the Knoppix method for proving that on any given machine Windows is useless and not the machine. SuSE isn't useless, but it's been damn annoying in many ways. OK. So now to tell you what has been happening between me and Jack today: 1. I start qjackctl. As always, MIDI works but sound doesn't, and I get the following output: 15:35:56.092 Statistics reset. 15:35:56.331 Startup script... 15:35:56.332 killall artsd 15:35:56.385 MIDI connection graph change. 15:35:56.900 Startup script terminated successfully. 15:35:56.901 JACK is starting... 15:35:56.901 /usr/bin/jackd -R -t500 -dalsa -dhw:0 -r48000 -p512 -n2 15:35:56.905 JACK was started with PID=16459 (0x404b). jackd 0.94.0 Copyright 2001-2003 Paul Davis and others. jackd comes with ABSOLUTELY NO WARRANTY This is free software, and you are welcome to redistribute it under certain conditions; see the file COPYING for details loading driver .. apparent rate = 48000 creating alsa driver ... hw:0|hw:0|512|2|48000|0|0|nomon|swmeter|rt|32bit control device hw:0 configuring for 48000Hz, period = 512 frames, buffer = 2 periods Couldn't open hw:0 for 32bit samples trying 24bit instead Couldn't open hw:0 for 24bit samples trying 16bit instead Couldn't open hw:0 for 32bit samples trying 24bit instead Couldn't open hw:0 for 24bit samples trying 16bit instead JACK: unable to mlock() port buffers: Cannot allocate memory cannot lock down memory for RT thread (Cannot allocate memory) cannot lock down memory for RT thread (Cannot allocate memory) 15:35:57.107 MIDI connection change. 15:35:59.117 Could not connect to JACK server as client. 15:36:10.502 Could not connect to JACK server as client. 2.

In each case I have tried to start a jack application (e.g. Hydrogen) and got a warning that I would get no sound. What's more, the warning was in each case correct and I did indeed get no sound. To add to all this, earlier today I tried changing the sound server settings in the KDE control centre and every time I did anything X froze completely and I had to CTRL-ALT-BKSP out of it. However I seem finally to have succeeded in getting arts to choose jack rather than alsa as the audio device, but I don't really have a clue how I did it, and I have no less or more audio functionality than before. Erm... Any ideas on how to get jack being nice with my Audigy driver and the jack clients? Many thanks Robert P.S. I have just joined the list, but I have already used the archives on a number of occasions and so I would like to thank all of you for making this resource so useful. P.P.S. Nice one Brazil. The Brazillian popular music repertory as a public archive: that stuff is far more important than the Louvre. It should become the flagship UNESCO World Heritage Website or there's no justice in the World. Yeah. I know there actually isn't much justice in the world, but I can still believe in it can't I? -- Robert Persson is powered by Linux.

RE: [linux-audio-user] Scratch-built DAW - what's your favorite?

by Reuben Martin

>Can we start with mobo's? Any recommendations, >horror stories, successes are most welcome. > >Stories? recommendations? I built my own from scratch. I would actually recommend it as opposed to prebuilt boxes because you can pick and choose hardware that will have good linux support. I bought a VIA chipset mobo, AMD Athlon-XP, and an RME audio card. Gentoo distro. No horror stories. (Well, I found I had a bad memory stick when I was building it, but otherwise no complaints) -Reuben

Re: [linux-audio-user] A real problem (DVD)

by Matt Barber

->* AFAIK, video DVDs cannot be mounted, only data DVD<- I know they don't need to be, but I haven't found a video DVD that can't be mounted (except with that damn broken drive). I think they're basically data DVDs with a certain file structure... a lot of them put in autorun binaries for play on windows machines and other nasty goodies (I'm looking at a DVD of Parsifal right now that has READMES, an interactual Player installer, and some other stuff along with the AUDIO_TS and VIDEO_TS directories which have all the .VOBs).. But I'm not sure I know the real info about that. Matt

[linux-audio-user] Streaming multiple sound inputs

by peter

Hi all. I have done a search on the archives and appoligise if this has already been covered. I would like to have 3 or 4 inputs of audio fed from some radio's external to my computer and stream the audio out to the world as different channels/streams so that users can monitor the appropiate stream for whatever radio. So How can I install a couple of soundcards and stream each input to a different port or whatever? Regards, Peter

[linux-audio-user] A real problem (DVD)

by Matt Barber

Hi, Here's something that's been stumping me: Our DVD drive (Plextor 708A) can read and mount CDroms and it can play CD-Audio, but it can't read or write DVDs (anything that tries to use it gives a "no medium found" error). $ mount /dev/cdrom mount: No medium found similar error message with k3b... The problem is not playing DVDs with xine or anything like that - I can't get the drive to even acknowledge there's anything in it. Some computer info: Dual Opteron (tyan thunder mobo) SATA hard drives (western digital) Fedora 2 planetccrma setup: $ uname -r 2.6.7-1.437.1.ll.rhfc2.ccrmasmp (using this kernel for now because cdburning in other newer kernels hardlocks the system -- through 2.6.8.1... haven't tested past that) here's something from /var/log/messages I get when I put in a DVD: Nov 30 12:07:30 madking kernel: hda: packet command error: status=0x51 { DriveReady SeekComplete Error } Nov 30 12:07:30 madking kernel: hda: packet command error: error=0x44 Nov 30 12:07:30 madking kernel: ATAPI device hda: Nov 30 12:07:30 madking kernel: Error: Hardware error -- (Sense key=0x04) Nov 30 12:07:30 madking kernel: Tracking servo failure -- (asc=0x09, ascq=0x01) Nov 30 12:07:30 madking kernel: The failed "Read Cd/Dvd Capacity" packet command was: Nov 30 12:07:30 madking kernel: "25 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 " the corresponding dmesg lines: cdrom: open failed. hda: packet command error: status=0x51 { DriveReady SeekComplete Error } hda: packet command error: error=0x44 ATAPI device hda: Error: Hardware error -- (Sense key=0x04) Tracking servo failure -- (asc=0x09, ascq=0x01) The failed "Read Cd/Dvd Capacity" packet command was: "25 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 " cd drive info: cdrecord -scanbus when run as user: scsibus0: 0,0,0 0) 'PLEXTOR ' 'DVDR PX-708A ' '1.04' Removable CD-ROM 0,1,0 1) * 0,2,0 2) * 0,3,0 3) * 0,4,0 4) * 0,5,0 5) * 0,6,0 6) * 0,7,0 7) * when run as root: scsibus0: 0,0,0 0) '' '' '' Disk 0,1,0 1) * 0,2,0 2) * 0,3,0 3) * 0,4,0 4) * 0,5,0 5) * 0,6,0 6) * 0,7,0 7) * scsibus1: 1,0,0 100) '' '' '' Disk 1,1,0 101) * 1,2,0 102) * 1,3,0 103) * 1,4,0 104) * 1,5,0 105) * 1,6,0 106) * 1,7,0 107) * $ cat /proc/sys/dev/cdrom/info CD-ROM information, Id: cdrom.c 3.20 2003/12/17 drive name: hda drive speed: 40 drive # of slots: 1 Can close tray: 1 Can open tray: 1 Can lock tray: 1 Can change speed: 1 Can select disk: 0 Can read multisession: 1 Can read MCN: 1 Reports media changed: 1 Can play audio: 1 Can write CD-R: 1 Can write CD-RW: 1 Can read DVD: 1 Can write DVD-R: 1 Can write DVD-RAM: 0 Can read MRW: 1 Can write MRW: 1 Can write RAM: 1 hdparm info: $ hdparm /dev/hda /dev/hda: HDIO_GET_MULTCOUNT failed: Invalid argument IO_support = 3 (32-bit w/sync) unmaskirq = 1 (on) using_dma = 1 (on) keepsettings = 0 (off) readonly = 0 (off) readahead = 256 (on) HDIO_GETGEO failed: Invalid argument $ hdparm -tT /dev/hda /dev/hda: read() failed: Input/output error Timing buffered disk reads: read() failed: Input/output error Not sure what other info to give. I don't have much of a way to troubleshoot the problem by process of elimination - I have a Pioneer drive that I can try later today... we have another box with the same kernel, but it's a P4 and uses IDE drives. My instinct is that it's some kind of conflict between IDE and SCSI, but it could be a problem with the 64-bit processors (using x86, though, not x86_64, which is not available on planetccrma yet) or it could be an smp thing (if it's not the drive) -- lame segfaults on the opteron box but not on the P4 box, so I think that is probably a 64bit/smp issue, and so this DVD problem could be similar. I will try the other drive later today and see if it makes a difference. Thanks, Matt

Re: [linux-audio-user] A real problem (DVD)

by Matt Barber

Hi, I thought of that... not here, though - scd0 is not a device (it is on my RH9 box, though - I think something changed with ide/scsi in 2.6): $ dd if=/dev/scd0 of=/snd/mbarb/try.dvd dd: opening `/dev/scd0': No such device or address $ cat /dev/scd0 > try.iso cat: /dev/scd0: No such device or address etc. Thanks, Matt ->I don't know about FC 2 but on FC 1 I use /dev/dvd. It is linked on my system to /dev/scd0. My fstab entry looks like this: /dev/dvd /mnt/dvd udf,iso9660 noauto,owner,kudzu 0 0<-
