windows 7 sound mixer

I have windows 7 OS on my laptop. The default audio output is the inbuilt speakers. I also have a wireless headphones set. When I connect to the headphones via bluetooth it is recognised and I can change its volume from the volume mixer.
But I am not able to control which programs play on which audio device; for example the browser sounds are always played on the the inbuilt speakers and not on the headphones. Is there a way to assign applications to play on certain audio devices ?

Can you make the headphones the "default playback device"? Go to the Control Panel/Hardware and Sounds and finally Sounds. In the Playback panel, if the headset is listed make it the default playback device. Then all the PC sounds will go to the headset.

hey thank you very much. that made it work.

Glad to help.
