Is it possible to extend the cable for the digital optical link used to connect playbar to a tv? I will have my playbar sitting on a hutch and the tv is mounted on the wall to a full motion rack. I want the cable to go down behind the hutch, into the wall and up where it comes out behind the tv. This will allow the tv to still move freely and wont require me to also mount the bulky playbar under with the tv. Will this work? Will any sound quality or lip sync delay suffer?
