Hi vanniko63,

You may assign either one of these two optical inputs to any input except the tuner as it is fixed. You would go to into the setup => input/output assign => Digital audio then simply assign it to any input you want. Keep in mind that your computer is the one that is providing the signal so it is up to the computer to provide it as the receiver is going to take whatever signal and decode it accordingly.

Thank you.
