The iPod cannot be synced. An unknown error occurred (13019).
To try to solve this issue, try the following steps:
1. Open iTunes.
2. Select the iPhone under Devices on the left side.
3. Click the Music tab.
4. Under the Sync music option, choose Selected playlists.
5. Uncheck the Voice Memos playlist.
6. Click Apply
For me the problem was with music and I have to go through and figure out what song of playlist is corrupt.
