Hey guys, I'm running ubuntu gutsy and the latest version of qjackctl in the repo is version 0.2.2. The latest release is 0.3.2 and I'm looking to get the latest jack too so I'm upgrading everything. Anyways, the requirements to compile Qjackctl are g++ , qt4-core (libqt4-core 4.3 package in repo), qt4-gui (libqt4-gui in repo) and qt4-xml (which apparently is a module included in libqt4-core). So, apparently, I've downloaded all the reqs but when I run ./configure, I get this error checking whether gcc accepts -g... yes checking for gcc option to accept ISO C89... none needed checking how to run the C preprocessor... gcc -E checking for g++... g++ checking whether we are using the GNU C++ compiler... yes checking whether g++ accepts -g... yes checking how to run the C++ preprocessor... g++ -E checking for grep that handles long lines and -e... /bin/grep checking for egrep... /bin/grep -E checking whether gcc needs -traditional... no checking for Qt library version >= 4.1... no; Qt 4.1 or greater is required Anybody know how I can fix this? I'm worried about installing the latest version of Jackd if I can't control it via qjackctl Thanks

Want to compile/install LinuxSampler in UbuntuStudio - help?

by dfro＠umich.edu

I have UbuntuStudio Gutsy installed on an Intel-based computer. I want to try LinuxSampler, but because of some wording in the software's GPL, UbuntuStudio removed it from the distro. They actually seem to have only half removed it. Qsampler, libgig, and liblscp are still installed with the distro. I don't see any purpose for including them, since they require LinuxSampler, correct? My problem is that I want to remove these 3 packages and do a clean compile/install of LS and all its dependencies, but synaptic says it will remove the ubuntustudio-audio package. I do not want to remove this, because I am sure a lot of .deb packages have this as a dependency. So, how do I proceed? Any thoughts? Thanks, dfro

problems with headsets under Gutsy and PClinuxOS.

by Christian Einfeldt

hi I am stumped with a problem using my microphones for recording my voice under GNU Linux. I have two headsets: 1) a plantronics headset with a mic, and 2) a Labtec single earphone with a mic. Both headsets work under the copy of Microsoft Windows XP that I keep for testing, but neither works on two systems that I have with Gutsy Ubuntu and one system that has PClinuxOS 2007. I have tried lots of different stuff, and most of it is just flailing around. Per the suggestion on this page, on my Gutsy system: http://ubuntuforums.org/showthread.php?t=710155&highlight=plantronics I ran $ alsamixer and it gave me the output that is linked here, but not sure if it is helpful or not: http://picasaweb.google.com/lh/viewPhoto?uname=digitaltippingpoint&aid=5183… I then ran this command, which seems to make me think that the system is seeing the headset: cje@rb:~$ cat /proc/asound/cards 0 [SB ]: HDA-Intel - HDA ATI SB HDA ATI SB at 0xfe024000 irq 17 1 [Headset ]: USB-Audio - Plantronics Headset Plantronics Plantronics Headset at usb-0000:00:13.1-2, full speed cje@rb:~$ But I am not getting any sound or recording with the plantronics headset, although I can get sound but no recording with the Labtec headset. I also went here, https://answers.launchpad.net/ubuntu/+source/gnome-media/+question/20753 and I tried to follow these steps, but I was unable to achieve step 8, which is set Channel Mode to 2ch. I was only give a choice of 6ch or 8ch. Any and all suggestions very much welcome! Thanks in advance for any help --- Christian Einfeldt --- At last I found a response that works for me! 1. In the upper right hand side of the screen there is an icon for audio (Next to date and time). 2. Right click the Audio icon and choose Open Volume Control. 3. From the Edit menu choose Preferences. 4. Make sure there are checks next to the following items: Headphone PCM Line-In CD Microphone Mic Boost PC Speaker Capture Channel Mode Input Source 5. Close the Preferences window. 6. Go back to the Volume Control Window 7. Click the Options tab 8. Set Channel Mode to 2ch 9. Set input source to Mic (not Front Mic) 10. Click the Recording tab 11. Click the mic icon for the capture slider to unmute the mic (there should no longer be a red x there). You can adjust the volume of your mic by using the sliders. 12. Close the Volume Control window. Now when you use Skype you will have audio when you talk. -- Christian Einfeldt, Producer, The Digital Tipping Point

Re: [LAU] [Consortium] OpenExpo 2008 in Karlsruhe

I think this is a very good opportunity to showcase some of the latest milestones in the linux audio realm. Do we have anyone in the vicinity who might be able to help in manning the booth?

converting mp4

by David Forsyth

Hiya I downloaded some free language lessons that are mpeg4 files (extension .mp4) so far I have found nothing that will play them, nor convert them. I have sox and lame, neither knows this format. Audacity just exits. I'll need to convert them to MP3 so my daughter can play them and do the lessons. FC6 + PlanetCCRMA any advice? -- David http://iwr.ru.ac.za/~iwdf/ If you receive email saying "Send this to everyone you know", PLEASE pretend you don't know me.

Burning lots of CDs

by Bob van der Poel

I'm getting to point where I need to burn a bunch of my new audio CD. Does anyone happen to have an application which will run 2 or 3 burners at the same time? I'd just have to pull a burner from a 2nd computer and install in my tower and cut my twiddle-my-thumbs time in half ... well, that's the theory. Right now I'm using k3b, and it works flawless for everything I throw at it. But, I don't think it supports multiple burners. And while on the subject ... are the ink jet CD printers worth getting just to do a 50 or 100 discs or should I just stick with the tried and true sticky labels I normally print on my laser? I really do hate inkjets, if for no other reason than the high cost of ink! Thanks. -- Bob van der Poel ** Wynndel, British Columbia, CANADA ** EMAIL: bob(a)mellowood.ca WWW: http://www.mellowood.ca

batch processing loops ?

by Dave Phillips

Greetings, I have a bunch of loops and I want to change their tempo from 120 to 115. I know how to do this with Rosegarden, for example, but I have a lot of these loops and it would be tedious to process them one at a time. Is there an app (preferably a console app) that can batch process my loops as I want ? Best, dp
