When using the ADV7619 i noticed the following issue:
When i plug the Apple TV into the port that is using the ADV7619 before it is powered the content that is outputted on the audio port is corrupted and unusable.
If i power up the ADV7619 first and then plug in the Apple TV there is no issue.
I am using ADI's provided software stack (we got that through NDA and SLA). All other sources seem to behave properly.
I'm using the latest Apple TV (4th generation) with the latest software 5.1
I believe the problem also appears with the 3rd generation Apple TV.
I noticed this thread but there wasn't a resolution posted:
