Jack can only use a single device (hw:1,0). it cannot use 2 separate stereodevices as one 4 channel device.
However...see here for one possible answer (using alsa multi plugin)
http://www.alsa-project.org/alsa-doc/alsa-lib/pcm_plugins.html
Look for section "Plugin: Multiple streams to One"
also this
http://alsa.opensrc.org/index.php/.asoundrc#Joining_devices_to_make_multichannel
I modified this .asoundrc to join 2 devices instead of 2 subdevices. Seems to work (couldn't test properly yet). Thanks a lot for the hint. I'll post more info tomorrow (almost 4am here, gotta get some sleep).
