Question Super frustrated trying to connect receiver to tv

Feb 1, 2024
I am looking for help in trying to connect my old Onkyo TX-SR605 to the new LG 50UR8000 TV I just got. The Onkyo doesn’t support eArc/ARC, but it does support optical. I have the cables, I just get really confused reading the Onkyo manual because it jumps around everywhere. Would really appreciate any help. Thank you!
