Adobe Premiere Pro - How to Make a 2K - 5.1 QuickTime using your Surround Sound Mix

Import the 5.1 Interleaved File into your Premiere Project

Select the file and import
Choose the Interleaved 5.1 .wav

Next need to check the sync in your final timeline.
Locate the final picture locked timeline in your project and make a copy of it by right clicking the timeline and choosing Duplicate

Load the copy of the timeline by double clicking it to load in the program monitor

Test your surround interleaved mix with the timeline you just loaded by dragging it into your picture locked timeline and check for sync.
Solo the track with the small 5.1 on it that is your mix.
Adjust by slipping the mix in the timeline if needed. You should not have to do anything if you didn't change your timeline after you exported for the mix.
If you did have to slip it to get it in sync note that number of frames you slipped the mix.
 
Once the mix is in sync with the video go on to the next step.
