Sound-recording going out in the bluetooth headphone

Audacity Help Forum GNU/Linux
1

I work under Linux (Ubuntu 14.04 LTS)
I would like to manage to register(record) with Audacity for Linux the sound of my computer going out in my bluetooth helmet(headphones) without other slightest background noise.
How do you do it precisely with Audacity?

Thank you for your help(assistant)
