Windows 7: Bluetooth headset connected but no audio

Hi!

I connected bluetooth headset to my computer and they were working well. Today I connected headset and tried to use it but nothing work.

I can see bluetooth on Sound Devices (as default) and also levels that go up and down when I play something but no audio on headset.

I tried also to connect headset to my phone and they are working. Microfone of headset is also working on computer and phone.



Why this problem??? I haven't changed anything!
