[Alsa-user] debugging no-sound with alsa + jackd + timidity (rosegarden4)

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 454-5900

Having never attempted anything like this before ...  I'm hoping to
run timidity with rosegarden-4, and everything seemed to be going
really smoothly, with just one small problem ...

there is no sound output

$ timidity -iA -Oj
TiMidity starting in ALSA server mode
Opening sequencer port: 128:0 128:1 128:2 128:3

$ cat /proc/asound/cards
0 [AudioPCI       ]: ENS1371 - Ensoniq AudioPCI
                     Ensoniq AudioPCI ENS1371 at 0xdf00, irq 10

$ aconnect -i -o
client 0: 'System' [type=kernel]
    0 'Timer           '
    1 'Announce        '
client 62: 'Midi Through' [type=kernel]
    0 'Midi Through Port-0'
client 64: 'ES1371' [type=kernel]
    0 'ES1371          '
client 128: 'TiMidity' [type=user]
    0 'TiMidity port 0 '
    1 'TiMidity port 1 '
    2 'TiMidity port 2 '
    3 'TiMidity port 3 '

rosegarden gives a status of MIDI OK and shows creating devices
for the Timidity playback and uses the following jackd command line

    /usr/bin/jackd -d alsa -d hw -r 44100 -p 2048 -n 2

when I play a midi file, there are no errors, no warnings, and no
sound.

am I missing a step?  Any advice, debugging tips, refs to appropriate
docs or whatever are greatly appreciated.

should it help explain things, here's my aadebug:
