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 profile, select Bluetooth Hands-free Audio and click the Set Default button. If you are using AV profile, select Stereo Audio and click the Set Default button.

PIM items sent from the Windows 7 operating system cannot be received correctly

Symptom: Personal Information Manager (PIM) items sent from the Windows 7 operating system cannot be received correctly into the address book of any other Bluetooth-enabled device.

Action: The Windows 7 operating system sends PIM items in XML format, but most Bluetooth-enabled devices handle PIM items in vCard format. If another Bluetooth-enabled device can receive a file through Bluetooth, a PIM item sent from the Windows 7 operating system might be saved as a file with the extension contact.
