Problem recording streaming audio...

With my previous PC, i was able to record audio streaming, with the new one, it does not work anymore… :cry:
In the devices selectable for recording, I can not find one that allows me to directly record what I hear in the headphones, because they refer to physical inputs (line or microphone).
The (onboard) sound card is recognized as a HDA Intel PCH ALC 1150.
Please, what can I do?
Thank you.

Here’s a thing from the manual.


This works on Ubuntu 16.04 but not on Debian Jessy, my daily used distro.
On Debian, pavucontrol does not save my setting, so after reboot I have to launch and configure pavucontrol again, and this is really boring.
Any suggestions?
