Thanks for posting this article. It's allowed me to start using Jack and Rosegarden again.
Last November 20th or so (it's why I went totally silent, Oleg), an update came down from Fedora 11 (I was also using Planet CCRMA repositories for audio). I only use the stable repositories and I consequently trust all updates that come down from either Fedora or Planet CCRMA.
That trust appears to have been misplaced.
For no readily apparent reason, I couldn't start Jack anymore. Time was extremely short for me. I tried the suggested fixes in the Jack error log output, but it didn't solve the problem. I next tried Fedore 12 and must have gotten the same update, since Jack wouldn't start with the same error messages as I got under Fedora 11. I've gone from then until Sunday, March 14th, without Jack, Ardour, and Rosegarden.
On Sunday I installed Arch Linux. No problems, except for searching the Wiki Forum to find out the port number needed to get my network printer server recognized so I could print under Arch Linux. I got that fixed yesterday.
I'm now running:
without PulseAudio (oh what joy!)
ALSA version 1.0.22, release 1 (if I've read that correctly from the PKGBUILD script)
Jack version 0.116.2, release 1
qJackCtl version 0.3.6, release 1
Ardour version 2.8.7, release 1
Rosegarden version 10.02, release 1
Audacity version 1.3.11beta, release 1
The other thing I like about Arch Linux is that it doesn't automatically check for updates, and it doesn't try to push updates on you. Now that I have a system running the way I want, I can leave this system as is for the next 10 years if I wish and there won't be any broken programs due to buggy updates. Oh what joy, again!
For What It's Worth,
Stephen.
