Vice caché on BLACK EDITION: desync sound

I am cameraman / editor in audio visual, so I had to take a GoPro.
Then the GP3 BE is actually an excellent camera, on that there is nothing to say, I will put 5 STARS on the video game.
Certe low autonomy of one hour, but given the mignaturisation this is normal.

As against the Black Edition suffers from an extraordinary bug.
After a moment the files are out of sync with the sound (the sound can have up to 2 sec ahead).
It has nothing to do with the power of the computer or TV.
This is a major bug unresolved by gopro (make the forum). For now, a solution that would work would be to format this card via Windows, whenever the rushes were empty.

But on a 64GB card, if the gopro decides to desync from 10GB, and you do not board with you, you have to type to you the rest of your vacation out of sync, and 2 days post sync on software mounting. HELL.
This greatly affects the note I put on GOPRO.
As soon as the 4 comes out, I quickly resell the 3.
