Why is the sound not playing when Im try to listen to FB videos?

I recently just bought my Boom 2 and I was listening to music and when I tried to play a video on Facebook but nothing could be heard. It did pause my music and I checked to see if the volume was down but it was not. I disconnected through Bluetooth and then I could hear the video fine through my phone. I connected it again through Bluetooth and no sound. I checked my Facebook setting for volume and that part was fine. So I checked YouTube as well as other apps that I watch videos on and I could hear it through the speaker. Is there anyone who could help me fix this or let me know if it does not work for FB so that I can know and just not connected with it while on FB? Thanks in Advance
