First command didn't play any sound but it at least worked and created a
connection but still only connected to the left channel only. The second
command didn't work at all.

$ gst-launch-0.10 alsasrc ! audio/x-raw-int,channels=1 ! audioconvert !
audioresample ! jackaudiosink

----------------------
$ gst-launch-0.10 jackaudiosrc ! audio/x-raw-int,channels=1 ! audioconvert !
WARNING: erroneous pipeline: link without sink element
----------------------

jack connection list (filtered) while the first command is running (as you see
the right channel has no input connection):

$ jack_lsp -c 'system:playback'
system:playback_1
   gst-launch-0.10:out_jackaudiosink0_1
system:playback_2
