In the Bugreporter you can read that you can't use ALAC files created with Rip with the sharing feature of iTunes. Maybe it will be fixed, maybe not.
But it is also important to "repair" the old files already in your iTunes collection. One way to do this is the following:
Code: Select all
for f in *.m4a; do ffmpeg -acodec copy -i "$f" "x_${f%.m4a}.m4a"; done
It creates new files with x_ in the beginning. I'm still working on a automatic way to delete the old files and replace them with the new ones without the need for reimporting them into iTunes.
You need ffmpeg for this and you need to keep in mind, that the cover art is not copied into the new file.
