5.1 pulseaudio - bluetooth - hdmi

Can someone explain how can we bind HDMI sound and bluetooth together?
What i whant to do is to use bluetooth to output center channel, and all the other channels remaining from 5.1 to be outputed on the HDMI.
It would be awesome to have it as a configuration in KODI, but intill then, just a pulseaudio example will do.
Thank you!!

This is possible. I had it done once to output on HDMI and Bluetooth headphones at the same time. But it requires some work and you have to read some docs to make it work the way you want it.
