Companions aren't bantering?

I just finished an 80+ hour playthrough. While I did hear some banter, it was VERY rare. I certainly noticed that my companions were dead silent for hours on end. When they did decide to banter, it was like a christmas present. I literally would stop what I was doing so that I could listen to it as it was as rare as finding the Loch Ness monster.

I figured that was "just the way it was". Now I am beginning to think that there is a problem with triggering. I wonder how often the companions are supposed to banter. For me it was probably once every few hours of gameplay. 

I also thought it had to do with the companions I ran with, so I tried switching things up but banter frequency was still very rare. Such a shame since a lot of work was done in writing and voice acting these things that some of us will not see/hear.
