Mac Mini and AVR

Looking into a Roon setup and have a basic question about using a MacMini as a core and connecting it to a home AVR. The Mini seems to have only the mini jack or HDMI to transmit the digital signal to the AVR to be converted to annalog. What is the recommended connection between a Mini and an AVR? Do we loose any sound quality using a Mini verses a dedicated ROON server from a partner that has a built in DAC?
