The first message I got was "Failed to create the audio driver (jack).
Cannot continue without it.
In the messages was "Jack server not running?"
Which seemed clear enough!

When I choose the audio tag & tell it alsa I get

08:15:22.922 Qsynth1: Failed to create the audio driver (alsa). Cannot
continue without it.

Likewise in the Midi tab, the Midi Driver settings alsa_seq and alsa_raw
gave "Failed to create the MIDI driver (alsa-seq)" and  "Failed to
create the MIDI driver (alsa-raw)" and only setting MIDI driver oss gave
no error message.

Changing Audio Driver to OSS I finally got some (distorted) output.
Chaning it to jack (after running jackstart --driver=alsa) I got some
clean sounding piano notes, though with too much latency to be very
useful.

I've done that, but I guess my main problem is alsa not doing what it
should.

24-bit directly? Some command line option?
Thanks - it is great to actually hear some output at last!
