Nexus 5x No audible notification while on a call

[mcgoss]

I have a Nexus 5x running Marshmallow. I have noticed that I get no audible notification of any other events, like calendar events, emails or Text messages while I am in a phone call. I have not found any way to enable this. I am not running Do not disturb so its not that. Are there any settings or add on software that will provide this function?
