More TV accessories
Since I am a kind and loving husband, I continue to search for ways to shield Mary from uninteresting football games (sometimes she doesn't even seem interested in interesting ones).
The television we had on the boat had an audio-out jack that did not shutoff the tv speakers. I could leave a set of wireless headphones jacked in and turn the tv speakers on or off as desired.
Both of my Vizios, and new ones I looked at in the stores, turn off the tv speakers when I plug into the audio-out jack. This is fine if I can get to the jack but means I can't plug the wireless headset base unit in and just use it when I have to be quiet. 
Determined to conquer my own tv set, I investigated the other connections back there. Sure enough, there is another way. I invested in an optical SPDIF to RCA Digital to Analog adapter and optical SPDIF (Toslink) cable.

and an optical cable.

I'm back to the setup I liked. I can turn the tv speakers on and off within the tv's setup (I really think I can just mute, I think the Optical link expects the attached audio equipment to handle volume). The wireless headphones let my watch without creating a disturbance and on rare occasion pick up the slack that my hearing aids leave. 
love it when a plan comes together ...
