Finally!  And thank you!
Now we just need Apple Music to work natively within Control4...

How is it possible that what seems to be a common problem does not have a common solution. All I am trying to do is have a receiver that powers a TV zone have the same audio timing as the rest of the control4 triad platform as this TV zone is in an open space with a bunch of other zones. So, in order to not here an echo there needs to be some correction. I think best answer is to put extra speakers in the ceiling that only work with the Triad platform and then just have the receiver as dedicated TV. therefore no delay and no part of the open concept living space without sound. Seems excessive, but it will solve it. Now, we just need to solve the subwoofer issue which is on the receiver but wanted for the audio zones as well. might just look for a sub with two line ins and run one from the matrix to the sub and the other from the AVR to the sub. 
again, my comment was around this is not a unique problem and based on responses to this, it clearly is an ongoing thing. just no clean answer to date. Lots of Band-Aids and trial and error. 
Everyone has been super helpful, really appreciate the feedback. I have tried a few of these suggestions (thank you to the community) but they don't seem to work for my application.

I wanted to follow up from our earlier post.  I've attached a couple of pictures of the way we do it.  We will always try to run the garage door opener wires back to the processor whenever possible.  If not, we locate the Z2io/secondary processor in a secure location.  The Lift master 893 Max does almost every garage door open lift master makes.  
We can then run a garage rail door sensor to either the main processor or the secondary processor to monitor if the door is open/close.  In the pictures below, we've tied the doors into the alarm system so we can monitor the doors through there.  
@RyanE I'd figured you'd appreciate the details.  

I'm surprised no one has done a Lua benchmark suite.   Unless the OS does per-thread throttling or something that prevents you from saturating CPU cores, I would think that would be helpful data versus trying to evaluate "snappiness."   I would not be surprised if the Core 5 has more compute power / system performance than CA-10.
