Hello people,

How well is the jack sense feature in modern soundcards supported in the 
kernel ? I opened up a few driver sources like hda-intel and found the 
word 'jack sense' in some files, but i could not find it being used anywhere.

Are there standard interfaces in kmix or equivalent software that use the jack 
sense feature ? If not, wouldn't it be nice to have a standard interface to 
expose this feature so that kmix and others could make use of in a device 
independent way ?

If yes, I would be more than happy to contribute to its development.

Please clarify.
