Oh, I just noticed, there's a Launchpad report for the same/very similar
bug here:
https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/960124
which has some discussion that may be interesting (apparently the extra
mic pin exists because the 'headphone' output can actually handle
headsets, or something). This bug seems possibly to be discussing a
newer model of the Z (Z13), but it certainly looks very similar.
