Bold 9650 -- audio controls not working on Moto s305 BT headphones

I can successfully pair my new Motorola s305 bluetooth headphones with my phone (Bold 9650 running 6.0.0.524) and play music in the media player. The volume controls on the headphones work fine, as does the phone button. However, the play/pause button and next/previous track buttons do not work. When the device paired it showed the A/V remote control with with a green checkmark meaning it should have worked. Is there a setting on the phone somewhere to enable remote control use I am missing or am I just SOL? Any help would be appreciated. Thank you.
