I have now done so, and got the same symptoms: no sound through the headphones
(except for a single "pop" during boot, which I assume to be related to
hardware initialization). Still no 'Jack Detect' switch either.
For completeness I'll mention that I tried with both settings of the
'Independent HP' switch. No headphone output in either case. Not even
if I explicitly select "Analog Headphones" as the output connector in
Sound Preferences (which mutes the rear speaker output).
