Hi Lin,
I have downgraded my system to 10.4 and was able to confirm that it doesn't
work perfectly either, though in a somehow "better" way. "dmesg | grep
think" gives the line you just mentioned. In 10.4 the behavior is:
headphone / mute button / sound
not plugged in / off / speaker
not plugged in / on / none
plugged in / off / both headphone and speaker
plugged in / on / headphone only
Another observation that may be useful: There is a light under the mute
button indicating state of muting. In 10.4 the light goes on and off as
muting gets turned on and off. However in 10.10 the light gets locked to the
state before Ubuntu boots; but even muting was on before Ubuntu boots
(therefore the light is always on within Ubuntu), muting still has no
effect.
