[linux-audio-user] Pure Data and 2.6.11.12 kernel -> freeeeeze!

by columbiatwo＠free.fr

Hello everyone. I decided to upgrade to a 2.6.11 kernel following the advices Maarten de Boer and Pau Arumi who gave a nice presentation at AES 2005. I was previously running a 2.6.8 kernel and everything was fine with my Asus L2000D laptop (SiS soundchip onboard running Trident4D ALSA driver, Evolution UC33 MIDI controller up and running). The only lack was realtime audio. I never dared taking the first step into realtime kernel tuning. I upgraded to the 2.6.11 using make oldconfig and tuning it for realtime (Security options and other stuff). Compilation went right. I compiled Pd again and when I tried starting it it froze the whole system: no mouse nor keyboard control, no X response (no graphical refresh)... I recompiled the kernel 3 or 4 times changing a few options, recompiled Pd as well. Nothing changes: complete system freeze. I'm running a Debian unstable, Fluxbox desktop. Anyone got a clue on what's wrong? Alternatively, what benefits will I really earn upgrading from 2.6.8 to 2.6.11? Maybe I can tune my good old 2.6.8 to do realtime as good as a 2.6.11? Cheers list.

[linux-audio-user] ide to scsi convertors

by R Parker

Hi, FC3 Tyan Tiger Dual AMD Adaptec Firewire Controler CoolDrives Dual Master two bay hotswap enclosure with the Initio bridge I've given firewire a fair shake. With my hardware it is unreliable. SBP2 is forever spiting out error messages. Hotswap events hang the SCSI bus and force power cycling. Has anyone used or got opinions on IDE to SCSI convertors? Here's a link to what I'm looking at http://www.addonics.com/news/media/2002/100202cnet.asp I intend to modify the Cooldrives enclosure by removing the firewire bridges and replacing them with the SCSI convertors. I'll run the enclosure off one channel of my ICP Vortex GDT8543RZ four channel RAID controler. I expect grey skies to turn blue, bankers to offer low interest loans and tickets for sporting events. It's to much to expect a social life so I'll reserve some optimism. Am I an idiot? ron ____________________________________________________ Yahoo! Sports Rekindle the Rivalries.

Hi, QjackCtl 0.2.17 update release is out. Directly from the change log: - Systemic I/O Latency settings are now featured for the alsa, oss and coreaudio backends, letting you specify the known latency of external hardware for client aware compensation purposes (thanks to Wolfgang Woehl, for the reminder). - Update on last backstage changes to the coreaudio backend options (due to Stéphane Letz. Thanks).

[linux-audio-user] Hig load when running rt-preemt/rlimits kernel.

by Frode Haugsgjerd

First, i whant to say thanks to the developers of OSS audio apps. I'm having great fun making smal tunes w. my guitars Ardour,Hydrogen,Muse,Zynaddsubfx,LADSPA and more. I have rebuilt these and others for Ubuntu if anyone is interested. My box never goes below 1.0 load when idle when i run my homegrown realtime-preempt kernel. If i run Ubuntu's stock kernel the load is near zero. Ardour and jack perform ok, no xruns with my old (-98) SB Live (10,7msec latency). But the system feels sluggish. I get the same 1+ load when booting with init=/bin/bash too. Details: Distro: Ubuntu Warty 2.6.12-rc4 w. realtime-preempt-2.6.12-rc4-V0.7.47-01 Pam patched w. rlimtits. Compiled from steambaloon source.(0.76-24) Celleron 2.2 and 512 RAM -- Frode Haugsgjerd <froh(a)fsb.gotdns.org> Norway

[linux-audio-user] dssi-vst trouble compiling

by MarC

I was trying to install dssi-vst and I found that the following link for downloading VST SDK headers is broken. do you know any alternative? The VST SDK headers -- http://www.steinberg.net/steinberg/ygrabit/index.html These are free but not redistributable. BTW, do you recommend me dssi-vst? Is there a better way to run vst in linux? Is there any really reliable way to run vst in linux? today I discovered that csound is planning to release version 5 with a great plugin VST support but I'm afraid that Linux users won't have the opportunity to enjoy it ;(

[linux-audio-user] Re: [ardour-users] AMD motherboard recommendations please?

My Seagate Barracuda drives are VERY quiet. My Celeron system is so quiet that the florescent lights in the room where it is are louder than the whole system. I have a fan on my Radeon card too. I got a lot of parts to make that so from Quiet-PC USA. I'm not affiliated with them in any way, other than being a satisfied customer. It's a little discouraging that of the two responses I got for my quest of which motherboard to buy that can run dual AMD processors, both of them said that their systems lock up. Two systems aren't that many, but it sure would be nice to hear from people with perfectly working systems too. :^) Happy quiet computing folks.... -- Kevin

An EMU rep has informed me that they have agreed to provide the ALSA project (specifically James) with a hardware sample. They don't seem to think we'll have much luck reverse engineering a driver. We'll just see about that. They mention that they won't be able to dedicate any development resources to it anytime soon, which makes sense given the widely reported issues with the Windows driver. The message implied that they might consider releasing some docs or (IMHO more likely) register info, but we'd have to make a convincing argument. Has anyone ever tried to figure out how many Linux audio users there are? Lee
