This afternoon, before we went to the pool, I finished loading files back into the file cabinet and broke down the bankers boxes to go back into the box they came out of.
After dinner, Gretchen had asked me to push the TV and the stereo cabinet in the family room back to where they belonged. Before doing that, I wanted to wire up the surround sound. With a couple of optical cables from the basement and some help from Gretchen, that's done now.
Now we can send sound from the TV (optionally) to the surround speakers. And it's in sync. :)
I guess I was right.
