Joe,
Sorry, have been busy lately. Today, I tried what you have mentioned currently the laptop speakers are the Default Device and the Bluetooth Headset is the Default Communications Device. I cannot select/change this, other than swapping between them. I find that it has to be the Default Device, otherwise there will be no sound in the headset. The "Set Default" button is greyed out when the Bluetooth Headphones is selected. As far as the Services tab, the following is checked: Audio Sink, Handsfree Telephony, Remote Control, Remotely Controllable Device. The following is not checked: Headset. Now, if I check Headset, is does not seem to make a difference. Otherwise the problem still persists.
