MDR-NC31 & Skype Problem

[Bobeobi]

Hi! I found problem with my MDR headphones and Skype. The mic doesn't work in pair with Skype, only for 1 sec people can hear me. 
Microphone works well in voice calls, Whatsapp and others.
Also others headsets, such as Mh1c works perfectly with Skype.

Tried to disable SmartConnect, Unmark OK Google, switching to speaker during skype calls also inaffective.

Any ideas?

What if you disable Noise canceling ?

Tried - nothing. 

Also tried with Z1 & Skype - everything works.

But my Z2 - won't

Does it work with other headphones?

[Bobeobi]

Yes. works ok. Only Skype, but I figuered when you call Skype with loudspeaker and then connect MDR-headphones, then they will work as they should. That is software problem after 5.1.1
