Hi everyone! Is there any supported hardware for DAB/DRM under Linux? A friend of mine is planning to have a media-server for his home and I try to help him as best I can.

Indeed. I forgot to mention that. Greets, Pieter

Hey, What is the best command line (or other) way to convert 24/48K to CD quality wiv files on linux? I can't seem to get ecasound to do the right stuff and I think sox is not 24 bit capable. Thanks b

No mic input after removing arts

by Mrugesh Karnik

Hi all, A while ago, being annoyed by arts interfering with skype, I decided to recompile my KDE without arts (I'm on Gentoo). Since then, my KDE does not emit any kind of sound for system notifications. The bigger issue is that my mic input simply does not `reach' any software. Anything said into the mic comes out from the speakers directly. The volume controls in kmix for the mic work correctly, however. How do I fix this? Oh, I haven't tried to use the mic anywhere outside KDE.. Thanks. -- ---------------------------------------- Mrugesh Karnik GPG Key 0xBA6F1DA8 Public key on http://wwwkeys.pgp.net ----------------------------------------

Ingen/Om as Jack Client?

by Sebastian

Hi, i've got a question, because I couldn't find anything in the documentation: Is it possible to run Ingen as Jack Client and if yes, how can I do that? I tried all the parameters and the GUI "ingenuity" (or similar) but either Ingen tries to connect to some unfamiliar servers or to start a jack-server itself (which doesn't work either). Are there other modular DSSI- and Jack-capable syntesizers besides Ingen (since AMS isn't DSSI-capable)? -- Best regards, Sebastian. web: linuxaudioblog.sternenhejim.de

Some Problems/Questions (about jack , qmidiarp and maybe other)

by luigi curzi

ciao/hello i use some applications on pc with a updated debian unstable to make some beautiful electronic (:-)) music. i don't have external midi controller or some instruments, i only use my pc. i have a creative audigy es. 1) what configuration can i use in jack for best performance? now i use this command line: /usr/bin/jackd -v -R -P70 -dalsa -dhw:0 -r48000 -p256 -n2 -P -s -zt with a latency of 10.7 ms; is it important latency in my case? 2) when i use vsthost with wineasio and some vsts i have some xruns and i can hear some poppings? is it a normal problem? 3) as midi arpeggiator i try to use qmidiarp (gpl but old, it is a dead project?) and hypercyclic (freeware, new and very good) but i can figure out how can use these softwares? precisely i don't know how link these programs with jack. excuse for my english. thanks in advice.

Re: [LAU] Looking for Portable Digital Recorder, on a budget

by The Other

I've recently received the Zoom H2 Handy Recorder and am very pleased with the recorder. So far I've been discovering its features and making the connections with my computer. As I posted recently, a very detailed review of the Zoom H2 can be found at: http://digitalmedia.oreilly.com/2007/09/13/review-zoom-h2-surround-recorder… And the Owner's manual can be downloaded in PDF format directly from Zoom at: http://www.zoom.co.jp/english/products/h2/ The H2 works with Windows XP, Windows Vista, and MacOSX 10.2 or later. There is an update to the H2's system file for Mac 10.5 (Leopard) at the Zoom site. I'm running a linux distribution, openSUSE 10.2 with a 2.6.x kernel. I am now happy to report that the H2 will recognize the H2 when it is plugged into a USB port. I was able to copy files from the H2 to computer and from computer to H2. I used Midnight Commander for the transfers. It wasn't necessary to use the BlueProton SDHC card reader to transfer files from the H2 to openSUSE 10.2 and back again. I'm using ALSA for the sound system/control on openSUSE 10.2. When I set the H2 to be a USB mic to the computer, my 'alsamixer' screen did not recognize the H2. Something about 'no elems'. Perhaps someone knows of a generic USB mic that alsamixer recognizes? But when I used 'arecord' from the command line with standard CD/wav settings, I was able to directly record to the computer. I hope to do some vocal recording soon. Regards, "The Other" Stephen Stubbs

Re: [LAU] Some Problems/Questions (about jack , qmidiarp and maybe other)

by Hermann Meyer

> can you provide an example of qmidiarp connection/use? > i don't know i can use it and make it sound. Okay, now I understand what you meen. You get a Midi in and Out put port in qjackconnect. Connect your Keyboard or vkeybd with QMidiArp Input Port, connect QMidiArp Output with your Synthy or WaveTable. You will see it work like a router an spliter. Now you can load the example demo.qma file . Play again your Keyboard and you will see for what you can use QMidiArp. You can write Pattern and play them with your keyboard. I dont know qmidiarp befor, its funy. But it's old and would't compile clean on my debian/sid. greetings hermann
