I installed the EFI update that silences the SuperDrive during Wake. I still get the sound.

After installing the EFI update, you then have to download and install the SuperDrive update.
Get it

Oh really? I thought it was included in the EFI update.
Thanks anyway.
EDIT: Installed it, works so far.
