Trying to have two audio outputs connect to a Roku TV, one connects by optical and the other is RCA

Hey, im attempting to connect a Sony MHC-V71 and a Vizio soundbar to my Roku TCL tv. The MHC-V71 connects by RCA and the soundbar connects only by optical, plugging in both to the tv does not work, only one audio output at a time. Is there a way to get around this?

Soundbar - Soundbar Vizio  S29020W

Stereo - MHC-V71
