This script and the behaviour it cause is for a default Debian install
and IMO this is idiocy. A default can be set by the kernel
configuration, what's bad with this? The most often cause for xruns for
the last month I read about, was a bad CPU frequency scaling.

I'm curios about the cause of "Jack vs. Alsa, PianoTeq demo: Alsa
wins!".

I experienced that as soon as jackd is involved, even if a media player
was ok with ALSA, I got xruns causing audible glitches, already without
CPU load, while there were never xruns or audible glitches as soon as
the CPU frequency scaling is set to performance, even for heavy resource
hungry audio productions. There might be two xruns when I start a
session, but no additional for the next 48 hours.

Ralf
