[linux-audio-user] a bit of a report on sounds expo 2004

by Chris Cannam

Just a note to say I've written up a short piece about the GNU/Linux Audio Centre at Sounds Expo last week in London, and stuck it on http://www.linuxmusician.com/ . There are a few photos too. Chris

[linux-audio-user] still have bad sound

by Dave Phillips

Greetings: I've narrowed down some parts of my current problems with sound. The mouse is definitely a noise-maker: I move, I get a not-nice ripping noise that tracks along with the mouse movement. I had hoped that the problem would be the nVidia binary video driver, but the problem occurs with the kernel sources driver as well. I've appended some background info in case anyone sees an obvious flaw in the system. A couple of things: I have no USB devices on this machine, so how can I get rid of the usb-uhci stuff hanging off the same interrupt as the SBLive ? Also, would it do any good to switch slots ? I've tried a number of different changes to XF86Config, got no joy from any. :( I've been working through the various suggestions from the Audio Quality HOWTO, nothing has worked yet. I'm open to any other non-$$$ suggested solutions...

Hi, For a few days now i am trying to do something with rosegarden (4.0.9.6) and fluidsynth (1.03) on my Planet box. One obstacle i could not yet pass is that rosegarden plays only one track, the one selected. I obviously miss something here. I do admit i know close to nothing about midi, but i would be gratefull if some could help me further. -- gerrit

[linux-audio-user] Kernel 2.4 low-latency patches -- combining?

by Chris Metzler

Hi. I've read the stuff on the LAD website about the two low-latency patch options for the 2.4 kernels -- Robert Love's preempt patch and Andrew Morton's low-latency patch. Each are described as having good and bad points in comparison. The way in which it's discussed seems to suggest that one should choose one or the other; nowhere is discussed whether it's a good or bad idea to apply both. But that seems to be possible; the Debian package page for AM's low-latency kernel patch indicates that it's compatible with the preempt patch. So I guess I'm looking for advice about this. Are they indeed compatible? Is there some reason why applying *both* would be a bad thing?

[linux-audio-user] Getting linuxevent to work with a Contour ShuttleXpress

by Frank Barknecht

Hallo, (sorry for crossposting, but this might be a Linux-using problem on my side.) I have a new toy (I couldn't resist, it's so cute): a Contour ShuttleXpress USB Jog/Shuttle control surface, info at http://contourdesign.com Now of course I'm trying to make use of it in Pd on Linux. It is recognized by the kernel as a HID device, and it is producing vrious characters when doing "cat /dev/input/event3" So I built Hans-Christoph's linuxevent from current pure-data.sf.net CVS, which turned up a first problem: EV_RST isn't defined, but used in linuxevent.c and linuxjoystick.c There is no EV_RST in /usr/include/linux/input.h I just commented the offending two lines, after that it builds and loads. Creating a [linuxevent /dev/input/event3] object shows this: #======== Configuring Contour Design ShuttleXpress on /dev/input/event3 Supported events: Reset (type 0) Event code 0 (Reset) Event code 1 (Key) Event code 2 (Relative) Key (type 1) Event code 256 (Btn0) Event code 257 (Btn1) Event code 258 (Btn2) Event code 259 (Btn3) Event code 260 (Btn4) Event code 261 (Btn5) Event code 262 (Btn6) Event code 263 (Btn7) Event code 264 (Btn8) Event code 265 (Btn9) Event code 266 (?) Event code 267 (?) Event code 268 (?) Relative (type 2) Event code 7 (Dial) Event code 8 (Wheel) Using 2 relative axes, 0 absolute axes, and 13 buttons. #======= Actually the device only has five buttons, but probably it's the same as the ShuttlePRO by Contour internally, which has many buttons more. Now the problem is: I pressed "start" or "poll" in the help patch, but there is no movement in linuxevent's output. Also, but this probably is my fault, one of the ShuttleXpress buttons acts as a right mouse button, that is, it opens the context menu when in Pd, or the window manager's root menu, when focus is outside of Pd. I did remove all references to /dev/input from my XF86Config beforehand. Does anyone have an idea, why I cannot get the device to play nice with Pd?? ciao -- Frank Barknecht _ ______footils.org__

[linux-audio-user] Need a new soundcard or more ;-)

by Michelle Konzack

************************************************************************* * Do not Cc: me, because I am on THIS list, if I write here * * Keine Cc: am mich senden, bin auf DIESER Liste wenn ich hier schreibe * ************************************************************************* Hello, Because my sound card is gone for two weeks or so I need anew one. I have following equipment: multimedia Workstation where I like to install the new Audiosystem I need entries for: 1. Tape-Deck 2. Record-Player (which support Schellack) 3. VHS-Recorder 5. Studio Microphone 6. Studio-Mix-Table (8 channels stereo and 4 mono) and one Output for the Amplifier ( 5.1 ??? ) But in the same time I like to connect the soundcards from my three other Workstations to the System too. michelle1 my main Workstation michelle2 my second Workstation devel-woody my Devel-Station My problem is, that I have not enough place in my Multimedia Workstation (PCI, ISA, IRQ) why I like to use USB. Now I have found the 'Yamaha Audio System DP-U50' and a completset 'Yanaha System TSS1' for the USB-Port. Does ALSA support such system ? Or is there a better solution ? Are there some (I know ther are) "Proffessionels" which can help me to find the right stuff ? Greetings Michelle -- Registered Linux-User #280138 with the Linux Counter, http://counter.li.org/
