[linux-audio-user] rt-sources and cpufreq; rt-sources and realtime-lsm

by Robert Persson

I have just built a kernel from the rt-sources-2.6.16-rt21 ebuild from the gentoo proaudio overlay. I used more or less the same config as I used for my previous 2.6.15-gentoo kernel (with custom reiser4 and suspend2 patches), except of course for the bits to do with preemption. With the previous kernel, cpu frequency scaling worked (despite a message I always got on boot telling me that it didn't). But with the new one it really doesn't work. Is this a know issue? I read one post from some other list suggesting that it was an issue for much earlier versions of the 2.6 kernel, but I couldn't really work out what was going on there. Also, there was a thread on this list a little while back which said that the realtime-lsm module is now deprecated. If this is so, what should I do instead to get realtime rights for non-root users? Many thanks robert -- Robert Persson Conspiracy Bears: Once upon a time there were lots of conspiracy bears...

[linux-audio-user] Firewire devices and Linux

by Yo'av Moshe

Hello! Me and some of my friends are going to live together for a while in a couple of months. One friend of mine is a musician, and he wants to be be able to record his tunes in our new place. I'm going to bring my PC with me, so we thought he'd buy some recording device and we'll connect it to my computer and will share it. I'm running Linux of course, and he got no problem with it, but after looking for a recording device for a while, it seems like Linux doesn't support most of them. The most appealing ones are those which can be connected via Firewire. They're cheap and functional. I heard about FreeBoB, but it seems like it's an (very) early project, and that I shouldn't count on it. Are there any recording devices like the "Focusrite Saffire", the "Alesis iO-26", the "RME Fireface 400", the "M-Audio Firewire 410", etc, that are around 350$USD and that Linux supports? In the worst case, I can always dual-boot, but I really wanted us to use Linux for the music stuff. Thanks! Yo'av.

[linux-audio-user] Mastering without mastering

by BJaY

I was just watching the talk on Protege at zkm 2006 and a bit of a crazy idea occured to me. In addition to storing qualities of each instrument like lead, string, percussive etc, a spectral profile could be generated for each instrument and stored in the database. Then, you could take each channel of your recording and pipe them (individually) into an app which would analyse their spectral content, and then suggest alternative patches to make the 'whole' sound like some idealised mix (there would be a selection of these, based on Genre perhaps). It would be like a magic button which would make a track sound immediately better. Any thoughts ? Bruce.

[linux-audio-user] Fst and Wine problem

by Juan Marcelo Rodríguez

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello, I'm trying to work with FST to load some VST instruments. The GUI starts OK, and if I don't change the preset, or If I don't modify any key of the virtual synth in case, it works. But, for example, with Crystal, a widely-know working Synth, I can start the synth, and also I can setup connections through qjackctl, and it works nice; but when I try to change the preset it fails, as all the other plugins later or sonnner do, the error message is: $ fst Crystal.dll gui_thread_id = 10 The program 'fst.exe.so' received an X Window System error. This probably reflects a bug in the program. The error was 'RenderBadPicture (invalid Picture parameter)'. (Details: serial 8753 error_code 174 request_code 152 minor_code 7) (Note to programmers: normally, X errors are reported asynchronously; that is, you will receive the error a while after causing it. To debug your program, run it with the --sync command line option to change this behavior. You can then get a meaningful backtrace from your debugger if you break on the gdk_x_error() function.) Sometimes this error "breaks" the environment and I need to restart all the apps to get it working again. I talk with the one of the FST developers, and he suggested me that is a Wine problem. I searched the net and I didn't find too much information about. Any ideas are welcome. Also If it's OffTopic, I'm going to send this to the Wine list, but Imho it's more suitable to talk with people from this list about this. I'm running kernel 2.6.16 patched rt, Jackd 0.100.0, Wine CVS four days old, and fst-1.7 with vstsdk 2.3. Thanks in advance, Juan. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.2.2 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFEZOXpwWB8GXdhYbcRAgvXAJ9ZEo0hKRfInwDPlBs6n/RXAkujSACfZIde oNZg7Iv9KNos5oVjvJqKiOk= =cfAN -----END PGP SIGNATURE-----

[linux-audio-user] rosegarden, chionic and mixxx hardlock my box

by Thomas Kuther

Hi people! Just tried mixxx-1.5.0-beta1 and unfortunately i have to count it to my list of "box killers". This list currently contains * rosegarden * chionic * mixxx Interestingly those are all QT apps. But QT works fine here, for example MusE just works like a charm. And now im interested in finding out what causes those three apps to completely hardlock my system. And they _really_ HARDlock it, in a way that the kernel doesn't even react on a sysrq+s/u/b call anymore. no keyboard, no mouse, nothing in any logs.. just dead. Crappy hardware also is not the cause i guess, as card 1 is a M-Audio Audiophile 2496, and card 2 is a ESI Juli@ - and as said apps like MusE, LMMS and a big number of other apps work just fine. I tested it on both cards, in case of rosegarden with both, direct ALSA and jack output, and it hardlocks the system shortly after the splash is displayed. I have no idea what could be the cause because i can't get a trace or anything and have to hard-reset the box. I would be very pleased if anyone has an idea where to start with debugging that. Thanks in advance Tom

[linux-audio-user] Hard disk choice and partitioning

by Link Swanson

If y'all were gonna set up a brand new Linux DAW (with WinXP on there too), what hard disk choices would you make concerning interface, partitioning, and filesystems? Specifically: 1. How many hard disks? 2. IDE or SATA? 3. Partition order and size? 4. Filesystem type? I'm not too concerned about price: I want the best setup for a DAW that will run PlanetCCRMA, 64Studio, and WinXP. Thanks! Link

[linux-audio-user] Rosegarden4 Freezes my machine, need to system reset.

by baldobe

I am having 3 different problems with RG4 on 3 different debian distros. Xubuntu 32 bit When I start Rosegarden I get the splash screen then after a while I get an error message flashing up that's too fast to read. Rosegarden does not start up. Xubuntu 64bit I get the RG splashscreen and then a crash sound output (breaking glass). I do not get any error message. aGNUla/deMudi Nothing works when I start it up, no keyboard, no mouse, nothing. The only way out is to hit the system reset button whcih is obvously no good for the system. I also takes longer to recover from sucha position becasue Demudi does a system disk check. I really would like to get Rosegarden up an running as I have ben trying to do so for about a year now (on and off)!. Please let me know what info I need to post to get help on this. Thanks for any help. -- View this message in context: http://www.nabble.com/Rosegarden4-Freezes-my-machine%2Cneed-to-system-reset… Sent from the linux-audio-user forum at Nabble.com.

Re: [linux-audio-user] Linux Audio SIP Conference Room!

by Lee A. Azzarello

I upgraded Asterisk for another project and it broke unauthenticated SIP calls. I don't really know how to fix it but I'll figure it out. If you know it would be a lot of help. -lee ----- Esben Stien <b0ef(a)esben-stien.name> wrote: > "Lee A.

[linux-audio-user] Rip sound from a VCD

by Peter Clarke

Dear all, I was trying to rip some sound from a VCD today. I was hoping to play it in one ALSA application (Kaffeine) and simultaneously record in another (Rosegarden or Rezound). But when I tried to launch the recording application, it said it had no access to the audio. I also tried launching Rezound, then Kaffeine. This time, Kaffeine said it couldn't access the PCM, and it played without audio. Does this mean applications can't share the sound under ALSA? Or am I missing something? I'm running Gentoo with 2.6.16 kernel, ALSA 1.0.10 (I think - not quite sure how to check this). Any hints welcome. Peter C
