No Audio from Headphones

I'e been looking all over the place for this. I recently switched to Resolve from Avid (I was actually looking for some hardware when I found it) and for most part have been pleased with it. I'm thinking of getting the full version in July or August.
I have a weird problem. Sometimes I edit on my laptop while hanging out with my family. I want to listen through headphones so as not to bother them- but I can't. It keeps playing through the speakers. I've looked all over, and found a lot of post about no audio at all, but none on this problem. Any ideas?
