Default Awful Popcorn Noise On Google Hangouts Video Calls

I have regularly used Hangouts on my other devices and while the quality has never been great, it got the job done.
On the Z2 though, Hangouts is unfortunately completely unusable for video calls due to an awful and constant noise.

As soon as the call connects I hear what sounds like popcorn popping and this only increases with time or trying to talk.
Mic noise suppression makes no difference and neither does turning the mic off and in again as the noise comes straight back.

It's very disappointing that this great device is seemingly incapable of handling a simple video call, does anyone know of a solution?
