How come you make the conclusion that this is limited to one specific
channel? To my understanding there are multiple channels where this
problem occurs.

The best to start solving this problem is to try to figure out what
happens with the recordings that are correct but still cause desync
problems. This has been suggested already by many readers. Since it
seems that only few people have access to the firmware source code the
debugging is quite limited..
