Hello everyone,
I remember some time back there were complaints on this list about the
linux-rt kernel in Ubuntu Jaunty not being up-to-par for audio work.
What were some of those complaints, and has the issue been resolved?

It does not work for me: 2.6.28-8-rt on a hyper threading PC causes high
load (IOwait) on one (virtual) CPU, and the overall CPU performance is
about 30% of the standard kernel. Real time behaviour is not at all
better than the standard kernel (more xruns even with low CPU load).
Maybe this is specific to my PC (what I doubt, it is the same for two
different PCs which work fine otherwise).

Hi,
In ubuntu jaunty, i use a plain vanilla kernel + rt patch, and it
works very fine (rare xrun)
here my .deb packages for ubuntu jaunty: http://msound.org/tmp/kernel/

I second that. I'm using becks's kernel for a while now on three

Another thing I add to a jaunty installation is recompiling the
libasound2-plugins package to include the alsa jack plugin (can't
understand why they leave that out)

Probably because they don't realise the usefulness and have been given
so much grief for stuffing up the pulse audio system in the past that
they have lost interest in the final step
i.e Jack + Pulse ootb.
JACK + Pulse ootb seems to be a pretty big issue at the moment for *all*
the distros except for CCRMA where Fernando has whipped up a short term
compromise until the dust settles with jack2 dbus support..

Hi Josh,
Well, I've certainly had my fair share of issues with Jaunty:
http://www.linuxjournal.com/content/judgement-day-studio-dave-tests-ubuntu-…
Like Emiliano I've replaced the Jaunty-supplied rt kernel with a custom
one, I think it was recommended on one of the Ubuntu forums. And as you
can read in my article, that was only one of the problems I encountered
with Jaunty. However, I must also note that I've been using that system
more often, and I'm pretty happy with it these days (not too happy about
the GNOME desktop though, I still haven't replaced it).
I've not kept up with development of Jaunty or UStudio, sorry, so you'll
have to look in the forums and/or archives to see what's new kernel-wise.
Best,
dp

I recently decided I wanted the rt kernel (on ubuntu) because I wanted
to improve performance of 'recording' rosegarden+fluydSynth in Ardour.
I went the apt-get install way and I got a working 2.6.28-3-rt. The
advantage was that I got the nvidia drivers working 'out of the box'. I
had compiled a patched kernel but then X (nvidia?) was not working. Not
sure if wifi is working as at the moment I'm using cabled network (that
was also an issue with rt in the past)
Audio-wise it seems to work well (near to null xruns). I had to very
ugly system freezes, one at boot one while working with audio stuff. But
havn't tested extensively.
Kind regards,
Lorenzo.
