Hey guys, sorry if this has been asked multiple times but I’m a bit of a noob when it comes to this kind of stuff. I have a PS4 + OLED55BXPTA + ARC. 
 TV audio output is set to pass through and the PS4 is set to Bitstream (Dolby) but when Blu-ray audio plays, even if the track is 5.1, the app shows at as being Multichannel LPCM 7.1.

 

Is this normal? Or am I missing something? 
 

cheers 


Steve.

If you are playing a disc with a DTS-HD Master Audio or DTS:X soundtrack, multichannel PCM is good. But if it is a disc with a Dolby TrueHD or Dolby Atmos soundtrack, the Arc should not be playing as multichannel PCM but as Dolby TrueHD or Dolby Atmos.

What are your TV’s audio settings set to?

As I understand it, this is good. LPCM is uncompressed data, and you’re getting the 7.1 channels of data you want.
