i want to connect 2 bluetooth headsets to my pc according to see video with headset for me and my friend.

Bluetooth does not offer to connect 2 Bluetooth headsets to one dongle then i imagine :

- to setup 2 bt dongles
- to pair each headsets to its own dongle
- to create with pulseaudio a virtual sink made of the 2 headsets

then i implement this . it works but there is a remaining problem.

if i restart pc then second dongle disappears in the list of devices in bluedevil.
i must unplug then plug the second dongle to retrieve all the setup of the second dongle.
