Center channel on Klipsch wireless wisa system not working.

[scorptrigger]

I'm having issues getting my center channel to work. It started as an intermittent issue but now it's constant. I have swapped the Klipsch wireless receiver several times. Recently Swapped to an Axiim Link receiver. Swapped the center channel speaker 3 times and I always have the same issue! Any ideas? I used this system for 2 years without issues and I have multiple speakers that I can swap into the center channel.

Thanks in advance, this is driving me crazy!
