I've had a long-standing issue that I can't get rid of and hopefully someone can help. Ever since iOS 9.3, the Sound Check feature has had issues with my music. With Sound Check enabled, music will start playing extremely loudly for about 5 seconds, then drop to it's normalized level; the same happens for older songs (70's), except they start really soft, but eventually rise to their normalized level 5 seconds in. At first I was able to fix this by having iVolume re-adjust all the volume tags in each song file, but with every single iOS update, the problem shows back up. The only solutions is a full restore. I want to try to force iTunes to go through it's "Determining playback volume..." process. Is there any way to force that to happen WITHOUT rebuilding my whole library, thus losing all my play counts that all my smart playlists are built off?
