I have than box checked, and I also have several voice memos that have synced just fine but my most recent memos will not sync. They are playable on my phone but are not syncing into iTunes... help!
Let me guess - only voice memos recorded before July show up? I have the same problem - no new memos can be detected by iTunes. They are visible and playable on the iPhone, but there's no way of syncing them, even though all earlier memos sync fine (and sync repeatedly, so that I have the annoyance of lots of duplicate memos when I sync).
