Has anybody been able to fully utilize this sound card using ALSA? I've been able to set up analog recording. But during playback apparently the ALSA mixer does not have all of the volume controls necessary. The card, as you may or may not know, has an external "break-out-box" with just about all of the internal sound card's inputs and outputs (very convenient btw). I'm able to control the left and right channels using the master volume control, but the card also has rear, center, and subwoofer channels as separate outputs. I believe I've found the volume controls for all of those except the subwoofer channel. I've tried every volume knob but the subwoofer never registers a signal. If anybody out there has this sound card and has been able to use the subwoofer channel under Linux I would appreciate some help. Thanks, Rolando.

These symbols are exported from the sound-core-module, which you have to load. Do a "depmod -a" as root to update your modules-dependency files. Then load your driver again with "modprobe usbua100". This should load all required drivers. If not, you have to list all dependencies of usbua100 explicitly in /etc/modules.conf (man modules.conf). > I'm a bit stumped here because I don't understand how the .o file can be > prduced if there are un-resolved sysmbols. An Object file is produced by the assembler, not the linker. If you link a prog, the linker puts together the o-files if he can resolve all symbols; in case of a kernel-module insmod/modprobe look if all symbols are resolved. > I also notice I have no audio facilites listed in the Mandrake Control > Centre. Does this machine believe it has no audio, and could somebody > please elaborate if at all possible? No sound-core -> No usbua100 -> no audio facilites ... Regards, Norbert

[linux-audio-user] m-audio quattro + alsa

by Dave Griffiths

Hi all, I'm using an m-audio quattro usb soundcard with my laptop using alsa 0.9.2. I'm experiencing the audio device periodically shutting down - I have to unplug and plug in the usb cable a few times before it comes back up. It is better than it was - I was getting system freezes with a previous version of alsa, so it sounds like the driver might be the culprit. I just wondered if anyone else has experienced this problem, and might have found a solution. It only occurs every hour or so of use, it's quite intermittent. cheers, dave

[linux-audio-user] SB Live?

by Mikhail Ramendik

Hello people, I am thinking of getting a Sound Blaster Live. But I want to be sure that there are Linux drivers supporting its Sound Font hardware synth and its S/P DIF digital output. So, are there such drivers and of so - which ones? The alsa-project.org page on SB Live says "MIDI on SB live drive not working properly". Does this mean that Sound Font sytnth will NOT work on SB Live? -- Best regards, Mikhail mailto:mr@ramendik.ru

[linux-audio-user] Crackling sound

by Moeflon

How come I get "cracks" in my sound when using spiralloop? When recording the output, there are no cracks in the wav-file... It seems to me the cracks are produced in some way by HD-read/write-operations. Is this correct? Howto get rid of them? Thx.

[linux-audio-user] freqtweak crashes...

by Michal Seta

hi all, I just got the newest freqtweak and it consistently crashes upon loading a preset. It does not matter whether the preset has been saved with some previous version or current. here's gdb output: Program received signal SIGSEGV, Segmentation fault. [Switching to Thread 32771 (LWP 1381)] FTspectralManip::processDelay (this=0x8151798, procpath=0x8151730, data=0x8161870) at FTspectralManip.cpp:820 820 *rdest = data[i] + (*rcurr)*feedback; IS anyone else experiencing this? I wouldn't be surprised if it was only me. ciao ./MiS

[linux-audio-user] [ANN] galan-0.3.0-test2 released

by torbenh＠gmx.de

galan-0.3.0-test2 is released. galan is a modular synthesizer featuring subpatches, event processing logic and more. LADSPA is supported. you can build your own synthesizer interface, placing controls where you want them. I have ported the features added to the galan-0.2 branch up to the 0.3 branch. - Lib directory is in place. - liblrdf support. - feedbacksafe delay added which enables you to have plugins in the feedback path like in ams. opengl does not work. i have some troubles with the gtkglarea 1.99.0... this caused me not to implement multiple jack output ports... i have now given up on opengl and will add the multi outputs/inputs next. if you want opengl use galan-0.2... 0.2.15 will be released soon, when the sheet library is updated and reorganized. -- torben Hohn http://galan.sourceforge.net -- The graphical Audio language

[linux-audio-user] Laptop Stereo Recording Problem

by Rajdeep Pradhan

HI sounding bees, I use my laptop(linux) to record speech with stereo microphones. The problem is on playing sound back using "cat filename >/dev/dsp", the output from left speaker is much louder than the right speaker. The sample file is recorded using "cat /dev/dsp> filename". I tried the gain settings in aumix, but the problem persisted. The mp3 songs sounds good with xine. Any suggestions?

[linux-audio-user] HELP: good sound card

by Joerg Anders

Hi all! I have ISA sound card AWE 64 with 24 MB RAM extention. This way I can load the sound font "8mbgmsfx.sf2". This is the one and only MIDI sound for my ears. All other techniques for instance software synthesis with TiMidity++ sounds terrible to me, as if the orchestra plays in a stock pot. Now I want to buy a new computer. Unfortunatley, most boards don't offer a ISA slot, only PCI slots. Therfore my question: Does anybody has experience with PCI cards on Linux? Perhaps somebody uses this (or an similary) sound font with some PCI sound card. (?) If so, please send me a recommendation! Note! The PCM sound is of no interest to me. It doen't matter whether it noises(or so ...). I'm only interested in good sound synthesis. Thank you in advance! -- J.Anders, Chemnitz, GERMANY (ja(a)informatik.tu-chemnitz.de)
