hey again i just picked up a bdp-s590 and connected it to my samsung 3d tv and it looks great and all but the only way i get sound is if i play it through the tv speakers..ive been using a samsung sound bar with speakers instead of my tv speakers cause it sounds better..and it works with my cable and my old bd player but for some reason i cant get it to work with the sony...do you have any ideas on how to solve this problem or do i just use my tvs speakers
