Description: headphone doesnt work, but gets output when selecting speaker(not availible)

Headphone jack worked in the Past (last year around XMas...)
plugin of a Headphone does not produce any output (but headphone is selected correctly in the mixer)
switch to speaker (unavailible) activates headphone output [solution suggested for other pulseaudio problems...],
but this also activates the speaker outputs
Its impossible to silence the speaker and get only headphone output
in alsamixer the headphone volume does nothing but speaker changes both
