The real issue is why the delay in the first place.
Let me describe what the FPP playing of the Sequence does: The audio comes on, the lights don't blink; then the lights appear to rapidly flash, in sequence with what was programed-- catching up with the audio; then all is sync'd between the audio and the lights and the rest of the sequence plays without any issue. Next sequence: same behavior.
Up on FalconChristmas, one guy had the same problem and put a 5 second "silence no lights" on front end on his sequence and the problem went away. BTW: When running the show on the Laptop, no problems. The 5 seconds "allows" the FPP to catchup without any lights blinking and sync up for the rest of the sequence. no one see's the funny behavior.
