How to connect home theater to pc?

Question

HTPC

I have JBL Bar 5.1 and 9.1
There are two screens: a monitor and a TV;
I need to connect the soundbar so that it plays sound both when I use the monitor and when I use the TV.
So the question is: Through what (what cable) to connect the soundbar to the PC, so that there is 9.1 sound?

Answer 1

On good - through a receiver. And in the receiver optics. On the bad - to look for zvukovuhu with 9.1.
