If anyone has run across the random gigantic audio static created in a sequence. The key to resolving this is to downgrade back to version 15.0. We've had three different editors within a week encounter this. Editing is fine and dandy and then one day, you open your project and beholllllld....static has been introduced into every audio clip within one or all sequences. You'll check the source file and it's nice and clean and you'll try dumping prefs, or creating new project and pasting the troubled sequence in it but don't bother....just downgrade.
We're sorry about the poor experience. We're working on a similar issue that has been addressed in one of our Beta builds. You may install the latest Beta build from the Creative Cloud Desktop app to check if it's working properly. Please refer to thislinkto know more about Creative Cloud Beta.
