FYI, sound-unstable git tree test/hda-hp-mic branch contains the new patches. Pass model=fujitsu-jwse option, and all features will be enabled
I was able to test sound-unstable this evening (reporting a kernel version of 3.8.0-rc7+). I passed "model=fujitsu-jwse" as instructed. The "Headphone Mic" mode switch influences the headphone jack when it's configured as an input as I expect is the intent. The speaker still works and the speaker/headphone controls behave as expected. In short there appear to be no regressions in these respects.
Can you confirm that the speaker really need this patch to work ?

No. The speaker required this patch:

My point was that the latest code revision hasn't broken speaker and headphone behaviour compared to that which I tested a few days ago.
The patch you referenced appears related to the ability to manually control the mode of headphone pins. This was a separate issue.
Does the headphone Jack or Mic Jack support imedpance sense to differentiate the Jack type or not ?
To be honest I have no idea. I have no personal interest in leaving this decision up to automatic impedence sensing and so I have not looked into it. Even if the hardware was up to it it is important to retain the ability to manually configure the jack mode, knowing that it will not change modes automatically under any circumstances. Live performance situations are notorious for making automatic detectors do strange things at inopportune times.
How can one tell if impedence sense is supported?
The behaviour of this notebook and e8020 will be different from other notebook
In what way? Is this related to the impedence sensing?
Even if impedence sensing is supported I think it's important that we don't loose the ability to manually set jack modes.
No auto Mic selection because CD and non detectable dock line in
That doesn't bother me for the same reasons as above.
