Hi Thomas.

Two things to try. One if you are using version 2016 and the other is just BIAB in general.

BiAB needs the audio file to have two bars of silence at the beginning. You can set this in RB as there is an offset button you would select. The tracks would then list as -2,-1,0,1,2 and so on.

With the current build of BIAB, imported audio has to be adjusted.
Open the audio editor, there is an icon on the main screen.

Rt click with your mouse on the audio file and select - the
Permanently apply Bar 1 offset to track by deleting or inserting silence.

Hope that helps. Also, I just made a post in the Recording, Mixing,Performance and Production Discussion Group about syncing audio with BIAB/RB generated tracks.
