My curiosity prevailed. It turns out that the
TV sound will play through the DVD/Radio/CD Home Theatre System.
All you have to do is select "AV IN" using the function either on the box or on the remote. Bad news is that it does not sound much better than the TV speakers
and you can't hear the rear pair if you are sitting in the slide.
Just as a reference, the system I am referring to is the no name bookshelf box
that is about 3" high and 14" wide. It has a USB and aux input on the front in the lower right side.
The recipe for perpetual ignorance is:
Be satisfied with your opinions
and content with your knowledge.
