DeckLink 4K as general Audio Output Centos 7

Hi,

is there a way to output all sound from Centos 7 via the DeckLink 4K Extreme 12G?
The same way as I can do in OSX and Windows.

I only have the "Dummy Audio" output selectable in the "Sound" settings of the Centos 7..

It's the Resolve Centos 7 distro.
Audio via Resolve works flawlessly..
I installed latest DesktopVideo version.

Thank you for your help!

cheers
