David:

Has something happened to your fix?  

I have been installing it in various 11.10 systems, and it has been
working.  

The latest success, was installing it in an Ubuntu 11.10 system, using
the Gnome Classic desktop (which you can still download).  That desktop
has 20% to 30% less overhead than the Unity desktop, so it is an
improvement.  On my 933 megahertz machine, I would get occasional
under-runs.  

Unfortunately, they have taken away all of the things that made it easy
to use (no more panel icons, no more desktop icons, and especially NO
CUSTOMIZATION).  So it's still very bad.  

I decided to do all my music stuff under xubuntu, and installed xubuntu
11.10 (on my 933 megahertz machine).  

After downloading the MIDI/audio software I use, I included your PPA,
and installed updates from that.  

Unfortunately, when I ran it, I got many under-runs, and it seems like
it is no longer fixed.  

I noticed that it hadn't installed the development files, so I installed
that from your PPA - BIG MISTAKE!  

It took out JACK (which I depend upon), and even after removing the
fluidsynth dev version, I cannot get qjackctl to work at all, and I
don't know why.  

I've tried completely removing things, but still it doesn't work.  I was
able to re-install qjackctl, but it won't initialize any more.  I think
some libraries it needs have been removed, but I don't know which ones,
or how to restore them.  

It looks like I'm going to have to totally re-install the entire system,
starting over.  

I really wanted to use 11.10 with your fix, but if it doesn't stay
fixed, my only option is to install 11.04.

But if I hide my head in the sand, retreating to 11.04, then I end up
with Fluidsynth not working on 12.04, and my entire project is destined
for the dust-bin.  

Sincerely,
Aere Greenway
