Interesting, I decided I'd try that (turn off ACPI), but then I had
absolutely no sound. JACK saw the external sound card, but no sound came
from it. And the system didn't see the laptop's built-in Intel sound
hardware, either - so no sound there.

So it's back to ACPI on and 64msec latency. Probably the best I can get
without a RT kernel. When I tried this using the Music 2 beta DVD, which
runs a RT kernel, I got sound but any latency setting below 64msec
contributed overruns to the experience of playing Zyn.
