Sound does not come from the Bluetooth headphone
Symptom: Sound does not come from the Bluetooth headset/headphone but comes from the local speaker
even though the headset/headphone is connected using Headset prole or AV prole.
Action: Do the following:
1. Exit the application that uses the sound device (for example, Windows Media Player).
2. Open the Control Panel by clicking Start Control Panel.
3. Click Hardware and Sound Sound.
4. Select the Playback tab.
5. If you are using Headset prole, select Bluetooth Hands-free Audio and click the Set Default button. If
you are using AV prole, select Stereo Audio and click the Set Default button.
6. Click OK to close the Sound window.
PIM items sent from the Windows 7 or the Windows Vista operating system cannot be received
correctly
Symptom: Personal Information Manager (PIM) items sent from the Windows 7 or the Windows Vista
operating system cannot be received correctly into the address book of any other Bluetooth-enabled device.
Action: The Windows 7 operating system and the Windows Vista operating system send PIM items in XML
format, but most Bluetooth-enabled devices handle PIM items in vCard format. If another Bluetooth-enabled
device can receive a le through Bluetooth, a PIM item sent from the Windows 7 operating system and the
Windows Vista operating system might be saved as a le with the extension .contact.
