Problem with bluetooth headset

Can anyone solve this puzzle that i've tried few days without any results:

OS: WIN 7
headset: NOKIA BH-604
here is link for further information of headset if it helps:

software for communication: Skype

I can use my Nokia BH-604 bluetooth headset normally for listening music or playing etc. but when I start VoIP call with my friend and try to play, I hear only the call. I tried also to play my MP3s during calling my friend but all I heard was the call.

I solved the problem - at least somehow. Now I can hear all the sounds from headset speakers and mic is working too, but the quality of game audio is terrible. Normally the sound quality is really good with my headset when im just listening music or playing without any communication software.

All sounds works with bad quality when I choose "Bluetooth Hands-free audio" (headset icon / mono) for a main device from sound devices list. But I can communicate with my friend and listen the game sounds.

There is other device "Bluetooth audio renderer" (it's stereo - with headphone icon, not headset icon). If I choose this for main device, sound quality is perfect. But then I can't use Skype with my friend.

And I don't really want to use my speakers for sounds, mic gets ALL sounds from speakers while playing and it's not nice for my friends ears while playing.


I hope you guys can understand what I mean. English is not my native language - maybe you've noticed it
