[linux-audio-user] Turning GTK+ Themes off in suse 9.1?

by Dan Mills

Hi All, Does anyone know how to switch GTK themes off in Suse 9.1. It seems to be picking them up from QT for some bizarre reason. This is annoying as I am using progress bars to implement level meters and it does NOT work well when GTK decides to render the things using expensive alpha blended pixmaps..... My pet louderbox project has gotten horribly expensive on this platform and I suspect that this is part of the reason. It normally ties up around 50% of a P4 2.8 but on this newly configured box it is sitting at about 90% - me confused. Thanks for any hints. Regards, Dan.

[linux-audio-user] Simple ALSA recording?

by Mikhail Ramendik

Hello, I sometimes do simple stereo recording. When I used OSS, I used Audacity to monitor the input levels (and tune them via the mixer), and then brec to record audio. But now I want to use ALSA. Which program can I use to monitor input levels, and which (possibly different) program can I use for simple, buffered, preferrably command-line recording? Ardour would probably be overkill. I'm not doing multitrack stuff or anything. And I really don't want to spend the time to set up JACK, especially since latency is not an issue at all. Yours, Mikhail Ramendik

[linux-audio-user] Fostex MR-8

by Wilbert Berendsen

Hi, I'm in the market for a simple mobile recording equipment, and the Fostex MR-8 looks nice to me. (http://www.fostexinternational.com/docs/products/mr8.shtml) Does anybody have experience with it under Linux? Esp: - the use of the USB with Linux (is it a normal mass storage device?) - is it possible to update the firmware from within Linux? (otherwise I'll have to have the shop do it for me) - is the contents of the flashcards usable when read with a card reader? thanks for any experiences, Wilbert -- Wilbert Berendsen (www.xs4all.nl/~wbsoft, www.kde.nl, www.kerklied.net) "Reporter: Mr. Gandhi, what do you think of western civilisation?

[linux-audio-user] ALSA OSS emulation?

by Mikhail Ramendik

Hello, I am trying to use the ALSA OSS emulation layer. But in both kernel and aoss versions, the same things happen. /dev/dsp works and is routed to hw:0,0 ; /dev/dsp0 , /dev/dsp1 etc. are just not available. This despite the fact that in the kernel emulation, I tried to set options so that /dev/dsp0 would be routed to hw:0,4 ; and in the aoss emulation, I defined a pcm named "dsp0". What can I do to enable /dev/dspN ? I don't want to be stuck with just hw:0,0 , as my spdif is on hw:0,4 . Yours, Mikhail Ramendik

[linux-audio-user] Finale+WIne not 100%

by Javier TM

Hi! following Mikhail Ramendik's advice, i put commdlg.* comdlg32.* commctl.* comctl32.* from a Windows 98 (second edition) machine where Finale 2002 was already installed (and works fine). I copied them into the \windows\system\ directory in wine's fake Windows drive. I put the following in wine's config: in the [Version] section "Windows" = "win98" in the [DllOverrides] section: "commdlg" = "native" "comdlg32" = "native" "commctl" = "native" "comctl32" = "native" == OK,but when i run Finale it shows the notes at the simple note edit bar, but it doesn't do the same with the score. I run it from the console, and debug shows the following: Unhandled exception: unimplemented function shell32.dll.DragQueryFileAorW called in 32-bit code (0x40a0f058). In 32-bit mode. 0x40a0f058 (SHELL32.DLL..data+0xd058 in shell32.dll.so): subl $4,%esp Any idea? Thanks!!! javier. -- Using Opera's revolutionary e-mail client: http://www.opera.com/m2/

[linux-audio-user] [ANN] QjackCtl 0.2.12 released!

by Rui Nuno Capela

Hi everyone, While lurking on CVS, here comes another step to this jack-audio-connection-kit Qt/GUI frontend: QjackCtl has been released: 0.2.12 is now public! Taken from the changelog: - Fixed some old and slow memory-leak due to redundand and repetitive call to jack_port_by_name() (discovered and solved, thanks to Jesse Chappell); some other free() and configure fixes were also applied. - Shiny display effect toggling has immediate feedback on setup dialog. - Added new usx2y driver support (EXPERIMENTAL). - New scaled connections/patchbay icons were added; meanwhile, all inline XPM icons were removed and brainlessly converted to PNG format. - New setup options as for the connections/patchbay view apprearence: larger icon sizes and font selection are now possible, to better ease manipulation on a touchscreen (feature requested for Lionstracs' Mediastation). - Connection line width follows icon size in discrete proportion. - "Other" setup options moved to a new dialog tab, "Misc"; new extreme item values, 32 and 16 frames, added to the drop-down list of the Frames/Buffer setting (as suggested by Mark Knetch). As usual, grab it from: http://qjackctl.sourceforge.net Cheers, and enjoy, rncbc aka Rui Nuno Capela

[linux-audio-user] [ANN] QSynth 0.2.2 released!

by Rui Nuno Capela

Hi everyone, After a great long time, lurking on CVS, here comes another step to this fluidsynth's Qt/GUI frontend: Qsynth has been released: 0.2.2 is now public! Taken from the changelog: - Minor configure fixes. - Meanwhile, XPM icon(s) were brainlessly converted to PNG format. - Engine panel settings are now properly saved on stop/restart. - Icons were added to the engine tab selector context menu. - Master gain front panel control gets rescaled and now ranges from 0..200, with midpoint at 100 (unit gain). - Added Mac OS X build instructions (README-OSX, by Ebrahim Mayat). - Soundfont bank offset option gets its trial time (EXPERIMENTAL); please note that fluidsynth 1.0.5 is needed to build on this feature, which is being properly detected and only enabled at configure time. - Output level peak meters are now featured as an option (EXPERIMENTAL), which must be explicitly enabled on setup for those to show up; in addition, overall GUI refresh cycle period has been reduced from 200 to 100 msec. - Top level sub-windows are now always raised and set with active focus when shown to visibility. As usual, grab it from: http://qsynth.sourceforge.net Cheers, and enjoy, -- rncbc aka Rui Nuno Capela rncbc(a)rncbc.org

[linux-audio-user] stereo to 2 devices with asoundrc ?

by Mikhail Ramendik

Hello, I have a task here that should be simple, but I could not guess the right .asoundrc configuration for it. I need to have a usual stereo pcm (no multichannel stuff) to which programs can output stereo sound. The sound should then get copied to two stereo devices (hw:0,0 and hw:0,4 , the analog and spdif outputs). The net is full of examples of virtual multicnannel cards, but not of this simple task. I tried to do something by expanding on existing examples, but this has failed. Please help... Yours, Mikhail Ramendik

[linux-audio-user] Tuning pdflush?

by Rick

Hi all, I recently switched to FC2 with the CCRMA 2.6.8 kernel. I was wondering if there is a way to tune pdflush in the 2.6 kernel like you could bdflush in the 2.4 kernel? I have seen advice on this list to set bdflush by adding *"echo* "10 64 0 0 2000 15000 90 5 0" > /proc/sys/vm/*bdflush" to the rc.local file, thus causing bdflush to write smaller chunks more often to disk instead of waiting for the "dirty buffer" to accumulate alot of stuff to write to disk all at once, possibly causing dropouts. Is there a way to do this with pdflush or is it even necessary with the 2.6 kernel? Thanks in advance. Rick B *
