I'm new on this forum even if I have known AVS for a long time.
I don't have HDMI on my amp and my projector anymore because of an overvoltage in my flat. My PS4 is now plugged in optical on the amp, which is a Pioneer VSX-919.
I've only the two front speakers now and I've been wondering which is the best format. I understood that Linear PCM was the best via bitstream. The thing is that my amp seems to be less vibrant than lossy dts or dolby counterparts, which is kind of paradoxical for me.
For the information, I tried bitstream and bitstram mix on a bluray in this 2.1 setup with an optical cable, and I've been surprised that with linear PCM checked :
In bitstream, I just have the lossy dts or dolby decoding in the bluray menu.
In bitstream mix, I have the lossless DTS-HD or Dolby True HD put forward in the bluray menu.
For those who were wondering what the real difference was between bitstream and bistream mix,we may have the beginning of an answer in the 2.1 setup.
The only way to have lossless sound via optical out on bluray films then is to highlight Linear PCM in bitstream mix.
Am I right ? I wanted to be confirmed on this theory.
I just got an email from 2K recommending to change my audio settings on the PS4 from HDMI to Digital Out (OPTICAL) and disable DDS5.1, DTS5.1 and ACC (with Linear PCM checked), they said that would fix the issue. Unfortunately it didn't work, still getting the audio cutting out in matches. I guess I'll have to wait for Sony to drop the 1.7 update, maybe it'll fix this.
That's exactly what I did to improve my 2.1 setup via optical out. And the difference is real for the movies with a really more detailed and shining sound. I watched Jaws yesterday night which is in 7.1. The sound is far better than when DDS5.1, DTS 5.1 and AAC are checked. It's logic by the way given that all the informations which go to the satellite speakers directly go to the front speakers now.
And when I tried to change between linear pcm, bitstream direct or bitstream mix in the PS4 bluray menu once the film had started, there was no cut of the sound as it used to be when DDS5.1, DTS5.1 and AAC were checked (DTS was then on the screen of the amp even if PS4 bluray menu was showing DTS HD MA in this setup) and I thought at the time that the sound was not very punchy : the dialogs were not very clear and pared back (I'm a French who's watching the original versions, when you don't catch a word, it's easier to notice when the sound is not crystal clear concerning dialogs).
By the way, I left it in bitstream direct because I know it's just the way it should be. In this setup, my Pioneer amp shows me STEREO on its screen. The pure 7.1 DTS HD MA in Jaws is converted in pure stereo with the default linear pcm 44,1 Khz or 48 Khz (which are automatically checked in the sound and screen menu, optical out branch) from the PS4.
It's important for those who are just like me in a stereo setup in optical out to disable DDS5.1, DTS5.1 and AAC (with Linear PCM checked). I don't know for those who are hooked in HDMI but for Optical, that's the way it is and I'm very happy to have solved the problem. Try it, compare and you wouldn't want to come back to the defaulft PS4 setup which automatically enables DDS 5.1, DTS 5.1 and AAC in its sound and screen menu.
Does it work direct to the TV? Did anything else work when connected? If it's not the ps4 you will need to work with the cinema system it whatever.
I just upgrade my PS3 to PS4 and when I open my PS4 it only give me 720p and 2.1 PCM instead of 1080p + 7.1 PCM.
My old setup is PS3 > HDMI to HDMI Splitter then one HDMI cable go through my receiver(DA2400ES) and another one to my monitor with HDMI-DVI.
If I turn off my receiver i will get 1080p but no sound or turn off my splitter and i will get 7.1 PCM without video.
It was working perfect on my PS3 for like 3 years until today.

send anything but 2.0 channel audio over HDMI. Tried every possible combination / sound toggle / configuration (both console and bluray playback software)...no luck.
Was ready to send this PS4 back as I considered sending the "optical audio" over the HDMI a defect (and convinced their CS rep of this as well), but really suspected the console
was fine. So I dug into my bin o'cables and pulled out an optical cable. Connected it and now getting DD 5.1 and DTS fine which is fine with me for the time being.
Hope this helps anyone out there in the same boat I was.
