Bluetooth audio won't play through home stereo receiver

This isn't networking per se, maybe it falls under sharing. For some reason my HP Spectre 2-in-1 recently quit sending audio to my audio receiver, even though it and the receiver both show it being paired and connected. I've tried unpairing and reconnecting, but audio still goes through the built-in laptop speakers. My Windows phone connects and sends audio to the unit, so I think it's something to do with the HP. Thoughts?

Wow, those attachments came out messy, but you get the idea hopefully.

Does, perhaps, the volume control need to point to the Marantz?

Bingo! That was beyond simple, but I honestly didn't know that setting was there. Thanks!
