- I had this EXACT same issue -
MY FIX:
I FIXED this problem by simply checking the "Manually manage music and vidoes" (under iTunes>iPhone>Summary> Options > "Manually manage music and videos") and Re-Syncing.
My Stats:
iPhone 5 with iOS 7.0.3
Current version of iTunes as of 3/17/2014 - (St. Patrick's Day!!! 😎) which is: 11.1.5
Under Options I have the boxes "Sync with this iPhone over Wi-Fi" (even though I did NOT do this - I used the cable) and "Sync only checked songs and videos"
Also ALL of the other boxes inside the tabs Info -thru- Photos were un-checked.
My Attempts:
Killing ALL Apple/iTunes processes
Restarting PC
Uninstalling then reinstalling iTunes
Hard/soft resets of the iPhone (normally, just to update, I have to factory reset and then restore from Back Up, because I have the iTunes curse, but NOT this time)
Also tried killing all background apps, and turning auto-lock to never
^However, when I got this to work, apps WERE running in the background, but auto-lock was on never
Using multiple usb cords - I used 3 different lightning usb cables
^When I got this working I was currently using the 3rd cable.
^^The first and original cable came with MY iPhone which I got around September of last year, and the other 2 cables came with iPhones purchased later on - ALL were iPhone 5.
All of these attempts were made MANY times in MANY different orders
Conclusion:
All I did was seriously check the "Manually manage music and videos" box, and it worked.
Some songs got deleted (but with iCloud, they were easily re-downloaded (did not even lose their places in the Music app) - I do not know the cause of this other than the deleted songs were purchased on the aforementioned iPhone 5)
All my Photos, videos, iBooks, Tones, TV shows, etc. are managed manually anyway.
Someone please tell me if this is rubbish or if it worked - thanks! 😎
