can someone please just tell me which blu-ray play to buy that will output DD5.1 to my playbar. My only goal is to watch 4K Blu-ray movies in 5.1. i know this issue has been addressed ad nauseam but it seems the more i read the more confused i become. i've also purchased a litany of switches or converters. but according to the app none of them seem to output 5.1. please help. i currently have a playstation 3. does it have the capability? thanks in advance.
