Mac Sierra FFIVX - Sound only works through headphones

Thank you for the response Clanmira,

Just for clarity, you have your Macbook connected to your Interface via a Thunderbolt cable and the Interface is connected to your Display via Firewire, correct? I'm assuming your Interface connects to a speaker system that is independent from your display? Are there any other components to your set up? Is it to provide and image or diagram to help explain the setup?

Is it possible to completely bypass the Interface? I understand that you may want to connect to a sound system, but is there a different way to set up everything? Maybe connect the Macbook directly to the display then connect the speakers to that same display?

Here is my setup. Like I said, everything else works when it comes to getting sound out of my computer through this system except this game.

Thank you for the diagram.

I have a few more questions. Is the iMac in your diagram an actual iMac or just a monitor. If it is another computer, are you plugging the headphones into that or the Macbook (when the sound actually works)? Are you able to plug the headphones into any of the devices (Macbook, display or interface) to get the sound to work? Or will it only work with the Macbook?
