And you should. I did the same test and the metronome is on the left.Check
the connections with "jack_lsp -c" (and you cables :)).
Anyway, the whole syntax is 'jack_auto,client'. It causes ecasound to
register a set of JACK ports and connect those to the ports of 'client'.
You can change the number of ports/channels registered with ecasound -f
option:
# register just one channel
ecasound -f:32,1,44100 -i jack_auto,metro -o alsa,default
# register 10 channels
ecasound -f:32,10,44100 -i jack_auto,metro -o alsa,default
By default the format is "-f:16,2,44100" (you can change this by editing
~/.ecasound/ecasoundrc), so ecasound registers two ports. As 'metro' only
has one port, only the first one is connected to ecasound.
PS If you leave the "_auto" out, ecasound just registers its ports,
but doesn't make any connections.
