Let it run for an hour, punched in the code, and the radio came right on.

BUT... there's no sound. This car has been sitting for just under a year, and is now back in action.

About six months ago, I turned the radio on, and at first I got no sound. Then after a minute or two it came on, but it was at a very low volume (even when turned up on the head unit).

Any ideas here?

When I turn the radio off, I hear it click through the speakers, BTW.
