I tried the above connection without success; silence. Am I expecting too much? Is there are method to make this work? I can try optical from Vizio TV to Oppo DAC section, but was hoping to reserve that Oppo input for another source (D-VHS).
I found the ARC connection with my own Oppo 103 rather iffy. After you are sure you are using the right TV connection (usually only 1 has ARC) and that the Oppo is enabled you may need to restart it a couple of times, or restart the TV.
