Last google app bugs earphone functionalilty

after last update of google app, my earphone doesn't work. First, I thought that was earphone, so I changed it, but result was the same. So, after various test, I have found it's an option in google app that stops earphone voice (I can ear but my voice don't go).
Could someone test this bug? In practice you must select, in the menu of google / voice / setup OK GOOGLE / use OK GOOGLE from any screen and than you have to use earphone (no bluetooth ).

I have stock updated rom with no root.
