The previews usually use a lossy codec for audio, and the feature lossless. So there would have been a new handshake.

But there's also the possibility that something is misconfigured with the player sending audio that is not supported by your receiver. What receiver are you using?

Pioneer PDP-5020FD, Marantz SR6011
Axiom M5HP, VP160HP, QS8
Sony PS4, surround backs
