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.
