Ah - just tried uninstalling jack and reinstalling, and jackd2 now
seems to work pretty much as expected. Seems I had a few kxstudio
jackd libs knocking around that seemed to be interacting badly with
the default ubuntu stuff..

I've just done some quick testing of AVLinux vs.

performance of jackd is significantly worse on ubuntustudio..
On AVLinux, I can start up jack (0.121.3) with 32 frames, and CPU runs
around 3%. On Ubuntu (jackd 1.9.10), I am getting 30%+ with the same
settings.
Checking top, I am getting pulseaudio at 30% and jackdbus at 20%..
Killing pulseaudio, jackdbus goes down to 13%, but this is still
significantly worse than avlinux..
I'm wondering if it is due to differences in new vs. old jack, or if
there is something else I can tweak?
