Headphones stopped working

Hi All,

Headphone jack of my MacBook Pro Retina (Mid 2014, OS X Yosemite 10.10.5) stopped working.

Speakers work alright, but all three headphones I tried are totally dead.

Before that I had installed CallNote app to make recordings of Skype sessions. Unhappy with the app I uninstelled it.

Can it be somehow connected?

Simple things like restarting didn't help.

I checked setting in Sound, and actually can't find Headphones option, only Speakers and the bloody CallNote, which is supposed to be uninstalled:)

Any ideas?

Thanks to everybody in any case
