You can always, when sending PCM, use an upmixer (DSU, DTS Neural:X or Auro 3D) in the processor/reciever to upmix the 7.1 PCM stream to use all the speakers. Even the height speakers.

The part about BD secondary audio being set to on is throwing me. In the manual for my UB820 and a Dolby home guide they both state that to get full Atmos and DTS X, both should be set to bitstream and the secondary audio set to off. They both state this setting on players is for an alternative audio track on the disc if some of your equipment doesn’t support the primary audio track. Not that this setting allows for a separate overhead mix to play for full Atmos or DTS X. Some clarification on this would help, thank you.

I’ve been having HORRIBKE audio delay with my OG PS4 and Den-in AVR-x7200wa. It’s most noticeable with GT7. Of course I’m using H-DMI and not optical. I decided to switch it to PCM from Dolby, and the delay during shifting, going over rumble strips or kerbs. Contact with walls or other cars results in about 1/4 of a second delay!!!! Switching to PCM corrected the delay. However, tone is different and I have to readjust the output of all 11 speaker for this particular input. GT7 has stereo or “7.1 surround. I don’t know if it is DTS or Dolby or Sony’s own code. I’m guessing it’s a SONY format. For some reason, both DTS and Dolby are causing a horrible delay which makes the audio from the PS4 to be ahead of the AVR output. I cannot use the audio delay on the TV or AVR. It makes the delay worse.

The audio on the disc is already compressed think of that or else the audio file be way to big. LPCM is called uncompressed because it dose nothing to the audio file it dosnt compress it. Bitstream dose compress the audio to be transferred over HDMI or Optical if your listing to the non HD audio format. Then the audio equipment revives the stream uncompresses it and decodes it.
