I have to give up a recent "how stupid story" on myself.
My college age kids were in town and stayed over a weekend.
They went home and when I got home and turned the TV on, I had no sound.
I have a digital cable box connected to the TV, I cranked the volume to max, nothing,
I checked all the cables, no help.
I called my daughter, no answer, I called my son, no answer.
About 5 minutes later my daughter returned my call, I said did you do anything to the TV
I have no sound? She said, "Did you turn the sound up on the TV?" I grabbed the "TV"
remote and turned up the volume. Sheepishly, I said "ya that fixed it."
In my defense, I never use the TV remote, the cable box remote does all the functions including audio level.
One of my kids turned the "TV" volume to zero.
In another few minutes my son called, I told him the problem, his first response, "did you turn up the TV volume?"
I texted my daughter about an hour later and said, "stop laugh at your dad!"
