[Rosegarden-user] How I fixed rosegarden's sync probs.

A little off topic, long and and rantish, but maybe this will enlighten a
few people on the list.

Quoth Mr McIntyre:

I would say half your hair-loss problems are due to your use of Ubuntu
Studio. I myself almost gave up on Linux about 4 weeks ago - more than 10
years evangelizing the thing - after a terrible run with Hardy. I decided
to upgrade to Kubuntu Intrepid + Ubuntu Studio. It was an unmitigated
disaster.

After finding out that there is no realtime kernel offered for Intrepid,
I started researching how to install an older rt kernel and came upon an
enlightening discourse where I discovered that the  kernels from Hardy
(2.6.26) are *seriously stuffed* as far as audio goes: crashes, xruns all
over, apps hanging that can't be killed, poor audio quality, MAJOR
problems with respect to Jack, etc. Added to that the fact that you STILL
have to manually hack files in /etc in order to actually get low latency
happening, I took one last deep Linux breath, decided to go back to
2.6.24.xx-rt, removed all the UbuntuStudio audio stuff, got rid of all
those horrible audio daemons (pulseaudio/esd/artsd), hacked away at some
config files  and recompiled a _select_few_ audio and video apps from
their respective svn/cvs/latest release, with the only exception being
ZynAddSubFX, the package for which is very nicely done.

The upshot is that I have a far more stable system which is, capable of
processing more complex audio setups than before. Rosegarden's infamous
synchronization between MIDI and audio is now dangerously close to good
(hint: leave the synchronization setting on "auto" and don't touch it -
ever). Apps have started working that didn't even run or segfaulted. It's
a good week or two out of your musical life, but rewarding when it all
comes together. I've recorded more in the last couple of hours than the
previous 3 months (not an exaggeration).

Advice:  avoid kernel 2.6.26 and avoid the Ubuntu Studio audio stuff
where possible. Sorry if that hurts anyone's feelings.
