You can add "-E start" to handle this (see ecasound(1) man page for -E, it
allows you to pass set of initial commands to run, so designed
specifically to address this problem).

Add "-chcopy:1,2" (see ecasound(1) man page for this as well) and "-f:,2,
-o jack,system". This will copy left channel contents to the right, and output
a stereo stream to JACK.
