Here's my problem: i can't get any audio out of Rosegarden.
1) Jack works perfectly with Ardour, so i don't think it's a jack
2) I've already used Rosegarden on Ubuntu 9.10, so i don't think it's a
distro or configuration problem: on a previous install of Ubuntu 9.10 on
the same computer, Rosegarden worked perfectly without any special
configuration. After formatting and reinstalling Ubuntu, Rosegarden
stopped outputting any audio.
3) When I play MIDI tracks, Rosegarden's Master output meter is showing
some activity, so it looks like the softsynths i am using (Hexter or
Fluidsynth DSSI) are working right.
4) Qjackctl's Connections window is showing the right connections
between Rosegarden's master outs and System's playback_1 and _2.
Anybody could please help me?
