I wanted to connect a Bluetooth headset and Bluetooth speakers. Both devices have been paired by Bluetooth driver without problems. I could connect each. But: its OK on the helmet. no sound on the speakers. I remove the headphones and then I get the sound on the speakers. I re-paired with the headphones and then I get good sound on headphones (after disconnecting the course speakers). Apparently the connection order of importance for the woindows 7 audio function accepts to work with both devices once they connected bluetooth.
