Ah, thanks a lot for your asoundrc file. I was on the right track with
my dmix setup, but I didn't think about the fact that the JACK loopback
side for simultaneous playback needed format and rate specifications. So
basically it goes dmix -> dsnoop for one direction and dsnoop -> dmix
for the other (in case that there are multiple applications that
simultaneously recording via the ALSA layer). Your setup doesn't cover
the last part, but I grant it's a pathological case since nothing comes
to mind (maybe Mumble and Skype simultaneously for whatever reason).
