This is also needed for EAC3 playback, if configured. It can be moved inside the
#if defined below.

Fixed, though slightly reworked the checks because clang doesn't like having
cmd_line unused w/EAC3 disabled, and also didn't like defining cmd_line inside
the case statement w/o an inner scope. Thanks!
