I ran into a problem when using my Bluetooth headphones on Windows 7. They support both the A2DP and the Hands-free profile, however it seems that only one of them can be active at a time.
On my other PC, Windows seamlessly switches to the hands-free when a call is received.
In the above image one can see that both profiles are connected, yet only one is active in sound settings.
When A2DP is manually disconnected, the headset profile becomes active.
Any help to how make both profiles switch seamlessly is appreciated.
EDIT: I found a situation how it should look when it works:
