[Tullia] “Not sure what you meant by needing to update AE and quicktime after making the switches change…”
Your audio issues sounded very similar to issues that users used to have. That gave me the impression that you were not using more recent versions of AE and QT. You can try upgrading AE to 5.5.1.
