Thank you - you may well be correct about the dumbness - although I had
thought that realtime was enabled - perhaps the tech at the show moved
some values trying to fix the problem- The hdspConf had indeed been
moved from 96k to 48 - no idea how or why and this was certainly causing
problems. Thanks for the responses - it is running and i'll take it back
to the show - which unfortunately has no internet installed.

Hi list - i have an installation that's been running for a
week and has
suddenly failed.
Uses ubuntu 11.10 and a hdsp/multiface setup. What is
happening is Jack
is failing to start
There is a "D-BUS: JACK server could not be started" error
when QjackCtl
this is confusing and misleading and just incredibly dumb. but, moving
on ....

not too smart, but okay.

ok, so device acquisition logic is just completely optional ... fine.
moving on.

and there we have the "root" of your problem. first thing to try is to
start varying the parameters and see if anything makes a different
(period size being the obvious one, but also sample rate).
