Hi, There are some rumors about the lack of need for an RT patch with new kernel, after 2.6.26.xx for making (realtime) music on GNU/Linux. What is true about this? Thanks in advance, \r

disadvantages of a realtime kernel

by Grammostola Rosea

... Some rumors say [quote]The realtime preemption patches are not only unstable, they are available for far less platforms. So, why hassle around and make a realtime kernel available in the repositories if Debian can work on making other security and stability related issues better?[/quote] Is a realtime kernel less stable? Are they available for far less platforms? Do do support the same hardware as the normal kernels does? Any other disadvantages? Thanks in advance, \r

Re: [LAU] RT patch not needed for new kernels (?)

> i'd like to update this machine to intrepid before any attempts of update, i STRONGLY recommend you to boot from any live cd and tar your working system somewhere to be able to roll things back in case you'll found intrepid's performance absolutely inacceptable. chances are that it will run slow as hell. that's what happened to me, and google says it happens to plenty of folks for some totally obscure reasons. -- sex, bike, open source!

The Drummer's Gigsaw (or the Drummer's Puzzle)

by Philippe Hezaine

Hi all, Here is the first draft of the new project (in fact based on the old Drummer's Free Art), of course more than perfectible: http://philippe.hezaine.free.fr/spip.php?article48 Unfortunately, at the present time it is in French but for the Lilyponder's it will be a bit familiar. And for the ones who don't play with Lily, inside you'll find the finished Merengue, let's guess what? ... with velocities! It's features are: text-based, each instrument in its own track, whatever time signature you want, and you will be able to write polyrytmmic patterns ( but there is not template yet ) I have posted the same question on Lilypond-fr, sorry for the cross-posting: I'm wondering if i can put it under a GPL license, keeping in mind that the future works will only be a succession of patterns include in short pieces. (as for the Drummer's Free Art.) At the present time it's under a Free Art License. Have fun. PS. Is someone can tell me what is the best in English? The Drummer's Gigsaw or the Drummer's Puzzle? -- Phil.

Re: [LAU] The perfect distro for linux audio...

by cunnilinux himself

just a few random thoughts. * the best distro i have seen myself _IS_ jacklab. unfortunately, it's outdated at the moment, and not available for 64-bit architectures, but it's still closest to the "perfect" (imho). * to speak about ubuntu studio - gnome sucks. too much gnome crap is definitely not a way to gain simplicity & performance. * any distro WILL be imperfect for linux audio, since it WILL also be trying to be good for generic desktop use at the same time, thus it WILL suffer from performance penalties & waste precious memory / cpu / disk i/o resources. * (imo) PERFECT linux system for audio should do AUDIO jobs very well, and all those unnecessary options to turn it to another 1024 things SHOULD be removed. as for me, i'm building the whole system myself, enabling all optimizations for my hardware & omitting anything i'm not going to deal with. but i know that way is inacceptable for the vast majority of linux users... -- sex, bike, open source!

Question on multichannel audio on Inspiron 1525 [Ubuntu 8.10]

by Peter O'Doherty

Hi, I know this is quite a longshot as it is so specific to Ubuntu 8.10 on a Dell Inspiron 1525 and the (few?) people using it..! Anyway, here goes... I would like to use the two headphone jacks + the mic jack as outputs to create a 6 channel output (3 x stereo). So in qjackctl or patchage I guess I will need to patch it like this: audio out_1 & out_2 to system playback_1 & playback_2 (going to 1st headphone jack); audio out_3 & out_4 to system playback_3 & playback_4 (going to 2nd headphone jack); audio out_5 & out_6 to system playback_5 & playback_6 (going to mic jack). My problem is that I am already a few too many steps ahead of myself! To start off with I can't even get the 2nd headphone jack working, let alone set the mic up to send a signal. I've looked at the help "Second Headphone Jack Does Not Work" but it concerns 7.10 and is not relevant to me: http://linux.dell.com/wiki/index.php..._Does_Not_Work <http://linux.dell.com/wiki/index.php/Ubuntu_7.10/Issues/Second_Headphone_Ja…> Can anyone help me at least get started with setting the 2nd headphone jack up and getting independent audio to it? At least then I'll have 4 outs to start with... Thanks a lot, Peter

playing one channel mono mp3's with audacious

by Atte André Jensen

Hi It seems that audacious can't play a mp3-file that only contains a single channel. Is there a way to achieve this? If not possible, can people recommend a player that can handle single channel mp3 files, preferably something that doesn't scan my disc, connects me to youtube, tags files, moves things into separate folders, thinks in terms of playlists, and syncronizes with my iPod or junk like that. Just a lean player that can be called from the command-line and preferrably is available through ubuntu's repos... -- Atte http://atte.dk http://modlys.dk

UA25 and xruns

by Dave Phillips

Greetings, I received my UA25 yesterday. The system recognizes it immediately, and audio I/O appears to be working fine. The MIDI ports show up in QJackCtl's ALSA connections panel, but I haven't tested them. Nice unit, but there's one big trouble with it: I get a lot of xruns from JACK. I've Googled for solutions, tried every suggested setting, got no joy. The only setting that works without xruns at all yields a latency of more than 30 ms (-p 512 -n 4 -r 44100). If I lower the period size to 256 I can get the latency down to 23.2 ms and suffer only an occasional xrun. Btw, the rtirq script doesn't seem to help this unit. I thought this device would get lower latency than the on-board soundchip, but the HDA chipset runs at ~17 ms latency with no xruns at all. Am I missing something ? The UA25's Advanced switch is on, the sample rate is set correctly. Any further suggestions ? Best, dp
