Problem:Seems solid. A Haiku: Loose Optical Port Volume knob appeared to work Easily returned Volume control worked for the Headphones when I held the optical cable in "just the right spot." I tried with 2 separate optical cables (with the clear rubber protectors properly removed), both required wiggling to get the audio to work. It was easy to put back in the box. I returned it.
Solution:
Loose Connections. Worked briefly while I held the cables in place.
