Hi Paul,
Thanks for your information. I will reply point by point as far as I
can and then tell you what my work around is.

Yes I did

That is true, there are no closure contact on my case, an Enermax
CS-800TA. However the C-Media Main setting control panel in the front
panel section shows the selected icon in bold and not shaded as it is
for the rear output connectors when the plug is absent. I assume that
this is done by ASUS to accomodate the lack of port sense switches on
most cases.
The diagram on page 5-11 of the manual seems to suggest that Smart Jack
settings are only used for the rear panel.

This is what I have tried.
BIOS set to Azalea Enabled and AAFP set to Azalia.
Checked headphone output at pins 1 & 3(port1 L/R) or at pins 5 & 9 (port
2L/R). No output in either case. I did check electrical continuity and
headphone performance so I know the obvious is not defective.
Then I reset the AAFP to AC97 and tried pins 5 & 9. Again no signal.
I had hoped to be able to have the earphones and the front speakers work
at the same time, but this doesn't happen. If on the rear panel, you
select earphone on one jack, say the black one, and select front
speakers on the lime jack, only the front speakers will work. If you
then unplug the front speakers, the headphone will work.
So it doesn't look like you can have both running at the same time even
though you can select them on the front panel.
Therefore my plan is to ignore the AAFP and run the front panel jacks
through to the back. I wanted to have on the front panel, a headphone
jack that would silence the front speakers when it was plugged in and
also a line input jack so that I could conveniently record from external
audio sources.
This does not seem to be viable approach, so I must resort to stone-age
analog switched jacks. I'll probably just use the front speaker
selection on the rear panel with a cable running from it though to a new
switched jack on the front panel.
The mic front panel jack will be wired through to the rear panel as well.
While I appreciate the cleverness of the Azalea system, sometimes these
things just seem to be too smart for their own good.

Yes I looked at this very useful document and appreciate the points you
make below.

Yes the ports are being remembered across reboots
