My quick search revealed no 12.04 debs. re: xvidcap PPAs. The last one seems to be for 11.10 (Oneiric). It may be close enough to run. I will try booting 12.04 later and try it. you can DL the deb file and run dpkg on it to install. https://launchpad.net/ubuntu/precise/i386/xvidcap/1.1.7-0.2ubuntu12 Has a link to the deb file for i386, but there is a 64bit page there too. -- Len Ovens www.OvenWerks.net -- Len Ovens www.OvenWerks.net

Don't mind spending money. You don't mention what players are subject to this stopping. Since you have all your mp3 material already, why not try all of the half-dozen mp3 players available? I've always had good luck with mplayer, but there is vlc, and even ffmpeg (or avconv as it's being rebranded) can play mp3 files. I've always found .wav file playback to be more stable than mp3, and seeking behavior is better. The processor doesn't have to do much, at the cost of storing a bit more data (One hour costs 1 GB, roughly.)

JACK on PicUntu devices (mini-pcs)

by Perry Kivolowitz

JACK does not appear to run on this platform (yet). There will be hardware with audio I/O in the not too distant future. It would fantastic to have JACK there too.

[OT] Roland XP-30 for sale

by Julien Claassen

Hello everyone! Just a quick notice: I'm going to sell my Roland XP-30 for reasons of space and the good old mammon. Bit I'd first like to keep it "in the family". If someone is interested, please send me an e-mail off-list and we can talk shop. The instrument is in good condition, it's mostly been in the studio and I don't smoke in a studio. :-) Right, I'll be waiting until thursday, maybe friday. If I haven't heard anything by then, I'll get it up on ebay. Warmly yours and sorry for the OT Julien ---------------------------------------- http://juliencoder.de/nama/music.html

Aeolus 0.8.4, text mode, Ubuntu 12.10

by Kevin Utter

Hi all! I installed Aeolus through the Ubuntu distribution, but of course, I can't use the GUI. So far I can't get any sound from it, but there could be several reasons. I'm using the text mode, and it appears that it is working, unless its not actually controling the organ. Does anyone know if this version's text mode actually works? I can't access the MIDI settings as they're in the GUI. Can I modify those setting in the ./stops/aeolus/definition file? Or do I just need to run a different version for some reason? I'm making the jack connections for MIDI and audio, and I'm sending MIDI currently with VMPK. VMPK seems to be working according to amididump, and its connections show up in jack, so hopefully that's not the problem. Any suggestions would be appreciated. Thanks much. Kevin

CD ripping

by R Kimber

If I rip the same CD on two different occasions, would I be right to expect the two sets of tracks to have the same md5sum, or is ripping not that precise? I've been using rubyripper and have a difference between two attempts on the same CD, though rubyripper doesn't report any problems, and each chunk is matched twice for each rip. The CD drive is fairly new. - Richard. -- Richard Kimber Political Science Resources http://www.PoliticsResources.net/

The recommended way of using PA is by session. This allows more options and I think is more secure. To run system wide, PA has to be started at boot time. Normally, PA is set up to auto find and grab ports, but the config files in /etc/pulse have some commented out lines that might give some ideas on only connecting PA to one audio IF. I would first look at the online docs available for PA about running it system wide. Then put on your sysadmin hat and play. There are some man pages included as well that may help. You are going into places beyond what I have tried to do. You are likely to find more help on the pulse audio mailing list than here though. > Ah, yes. Thanks for pointing these out.

Or, is the profile what one creates with pavucontrol? look in /usr/share/pulseaudio/ and subdirectories. -- Len Ovens www.OvenWerks.net
