Layers not synced with audio playback

Hello, I'm currently in a show running content on V561. Presets triggered manually with mouse.
2 @ 1920x1080 for Left and Right
3 @ 1920x1080 for blended center screen
Layer 1 - SL,
Layer 2 - SR
Layer 3 - Center Right
Layer 4 - Use Layer 3, Center
Layer 5 - Use Layer 3, Center Left
I have 3 files for each screen so only the center file has audio.
I'm not usually playing audio from Catalyst, but am for this gig.
Even with all layers in play mode 70, I still have issues with them playing in sync.
I've been able to fire via timecode, and that seems to help.
Is there something I'm missing?

what's your setup
you need a 50 or 60Hz system depending from where you are
it's syncing but you have refresh rate problems

Try sync id, (layer 1 - center, id=1. layer 2+3 sync to id 1), and lock refresh rate in catalyst control window.

your monitor screens needs to support 50Hz aswell
lock refresh rate to the 2nd output
somehow I get more stable performance/refresh rate problem with everything set to audio playback instead of sync ID
but all if this is very experimental
