* xduoo x3ii/x20: Better line out support * less granular volume settings (too many steps before) * Better handling of swiching sample rates * Log actual sample rate in debug menu Most credit goes to Roman Stolyarov Additional integration [re]work by myself Change-Id: I63af3740678cf2ed3170f61534e1029c81826bb6
