Try this: Add a blank layer, put a sound on it, set it to stream and infinite loop and lower the volume of the sound so it isn't heard. The timeline will constantly sync with that layer, so the timing on any sound effects you've added in will match up the way it should.
That's what we do and it always works.

and add that clip in and delet the rest

Yeah, if it fails me again that's probably my next solution. Thanks!
