My audio system does not remember the choice of input when I turn it off it goes back to radio no matter what I listened to last. Settings under setup/audio common and radio are grayed out? Audio used to remember what I was playing last and those grayed out settings used to be available.

A common complaint with a not well-established fix.

Does the radio allow setting up a profile for each driver? If so, reset it or set one up.
