No, there is no need in open kernel or inception. It should work without any hacks. It just seems like current jack state in HAL was stick at "inserted" while audio state was like it's "ejected". Fix gets current value from HAL and it wes continiously trying to "eject" it. After manual run of "switcher headphone", it get in sync and started to work correctly. Excuse my english if the explanation is bad.

And I just received a report from one more user who get fix sticked at speaker state. Seems like this is serious problem. May be we will need to have two distinct icons for speaker and for headset in order to avoid unsyncing... Or make it switching between two states without checking current state from HAL.

Do you mean these 'magic' binary blobs? If you want to find other events, for example, for TV-Out, I will do this.
