[LAU] Problem with sound on Rosegarden

Hi, I'm running Rosegarden 10.02 on Ubuntu Lucid and am having problems with audio output. I am not using external midi hardware so am reliant on software synths. The steps I've taken are: Run qjackctl, run Qsynth (which has been loaded with Unison soundfonts). In Rosegarden I've selected General Midi Device from the Playback parameters and 1. Acoustic Grand Piano from the Instrument parameters. When I load a midi file (created by Lilypond) it plays with no audio although the level meters on the track do indicate it's getting some kind of signal. What am I missing? And, does Qsynth need to be running at all?
