Is there a red light coming from the AUDIO OUT port? If so, remove the 3.5 mm plug you use to connect the speakers to the Mac from the Mac's audio out port, and see, if there is a red light. If so, repeatedly plug and unplug the 3.5 mm connector until the light goes away, as the red light is the indicator of the digital, optical audio out being enabled, and sometimes it just gets stuck.

I read online and tried that....I was originally listening to my headphones and kept doing that however I never did see a red light...so that didn't work...any other ideas?

Check System Preferences > Sound > Output or OPTION/Alt click the sound/volume icon in the Menu Bar and tell us, what is listed and checked as Output Device.

Just did that and all it says is system preferences there is nothing to select other than that

Same problem here.
No red light ( spdif dont work ), no analog sound and no device.
Faulty logicboard ?
PSU, SMC reset and cleaning 3.5 output didn't work.

Could be a software issue, my recommendations:

1. Open another user account and see if the issue persists. If it does...

2. Backup your files and restore your OS. Most likely something corrupt. Before putting your data back, try plugging in a pair of headphones and see if it works.

3. If it persist, it is most likely a hardware issue.

Silly Question ~ MUTE

This is the input and output screen shots

Silly Question, but you DID notice that the system has been 'Muted'.. I hope.. and if NOT, then I will suggest 'hitting the Mute/F10 button' to see if anything magical happens..

Usually an Increase in Volume will disable the MUTE, but I cannot see why else it would appear as such here.. Good Luck!!
