Windows 7: Creative T12 Wireless auto-connect after reboot

Hello,
on one of notebooks I have Windows 7 Professional SP1 x64.
This laptop uses external speakers by bluetooth - Creative T12 wireless.

Notebook has Intel N2230 wifi/bt card.
I could pair devices, but i can't listen to anything on speakers using standard Windows BT drivers.
I installed intel drivers, paired devices again and now I can use it (start -> devices and printers -> creative t12 -> select "listen to music" on services box).

These speakers are selectes as default audio device in control panel, but after reboot Windows doesn't connect automatically with them. I always must use start -> devices, or click BT button on speakers.
On second notebook with Windows 8 system automatically connect with speakers on startup / reboot without any problems (also with intel bluetooth module).



How can I do it in Windows 7?
