start JACK first, then tell QSynth to use JACK as its output, then it
started and played once from Rosegarden. Next time I tried it, QSynth

unconnected."

If your soundcard is hda intel, there is a known problem, where crackling
occurs if the "Periods/Buffer is set to the default "2". The cure is to

Qjackctl's setup, settings, and change it to "3". Matthew Smith wrote:

There you go - so it can be done. Thanks Ron.
Think I'll stick to my external card though - better connectors,
headphone monitor, etc. (And hooked directly into a Soundcraft Compact
10 mixer.)
One day I might actually get the time to use all this - haven't even had
the chance build myself a non-crashing Rosegarden yet :-(
Hmm, my Rosegarden 1.7.0
installed from package in Debian Lenny/Sid
repositories, running with non-RT kernel on a Toshiba laptop also using
Intel HDA sound, doesn't crash.
