How to play music from a browser through a non-primary (secondary) sound card?

Question

In contact with

OS: windows 7 home edition.
I need to listen to music from VKontakte on the sound system built into the motherboard.
And logitech bluetooth headphones to remain the main means of playback.
Now I'm downloading music to the screw and listening to the VLC player (in which you can specify the playback tool). The problem is that I don't want to download. I want to play directly from the cloud. How?

Answer 1

How do you listen to music that goes into your headphones?

Answer 2

I don't listen to music with headphones. Headphones for skype, for youtube.
There are several people in the office. I want music on the speakers through the built-in sound system.
Music does not distract colleagues.
Skype and YouTube from the main browser (Chrome) can be distracting. That's why I use headphones.
