1. HKLMSOFTWAREWidcommBtConfigServices 005Enabled - Change value to 1. 2. HKLMDriversBuiltInWaveDevDll - Change value to BtCeIf.dll
Reset device, Run bluetooth manager and connect to headset.. partner. right(hold) click and connect When it gets connected, you will hear a beep from the headset like you are getting a call. Answer. AFter that, all the sound will be routed to the headset.
