Connecting a old sony 5.1 home theater to PC

Nov 25, 2018
Is there a way I could connect my PC( asus z170 pro gaming motherboard) to Sony 5.1 home theater (DAV-DZ270). There is no SPDIF output in the player. I connected it to my PC via aux cable and getting a stereo output. Is there any possibility that i can get a true 5.1 output.:/ Thanks in advance.
