I just started getting this error message when syncing my iPhone 4, shortly after upgrading to iTunes 10 (not sure if that's the cause or not).
I've tried the following, to no avail:
- Unchecking "Sync Music", syncing, then rechecking it.
- Unchecking "Include music videos"
- Unchecking "Include voice memos"
- Deleting all of my voice memos from iTunes.
- Deleting everything I've added to the iTunes Library in the last week (not a ton, but still got rid of it just in case)
What's sort of odd is that unchecking and rechecking "Sync Music" seems to do
something but it still doesn't work:
Before unchecking it, I get the "unknown error" message right away when I try to sync.
After unchecking, hitting Sync, rechecking and hitting Sync again, it does filter through all 961 songs in my library (and takes a few minutes), giving the impression that it's working.
Ultimately, the same "unknown error" message pops up again... no matter what I do.
Does anybody have any other ideas?
