Sound goes to speakers, not bluetooth headphones

System is openSUSE 12.3 KDE 32-bit on a ThinkPad X-41. I have a Plugable USB-BT4LE Bluetooth 4.0 USB Adapter and EElectronics Air-Fi AF32 Stereo Bluetooth Wireless Headphones. The KDE bluetooth tools show the headset is paired and connected. However, when I play an audio file, the sound comes from the laptop speakers, not the headphones.

How do I direct the sound to the bluetooth headphones?

Thanks,
Howard
