I've read a fair amount of threads on this site, but never really posted anything yet! I've had a living room setup for quite a while and recently just changed my settings around so that I have picked LPCM to get lossless / uncompressed audio and the best possible sound from my setup. Before I've always had it set so that I see the Dolby Digital 5.1 / HD or DTS 5.1 / HD lights show up on my receiver. I basically want to be sure my changes are okay and I'm getting the right output as I should be for my setup. It's crazy how many people in threads have said yes to LPCM then others saying to get their AV showing the DD/DTS/HD lights instead and go for that.
First of all, my setup:
AV: Sony STR-DH820
Speakers: Tannoy Mercury V4/V1/VC
Cable: Cambridge Audio Ultra 100/4mm Banana Plugs
Sub: BK XLS200 MK2-FF
So, the two devices I have changed settings for are my Playstation 3 Slim and Playstation 4. Both are hooked up via HDMI straight into the AV. It's my Playstation 4 I use the most now.
I use my Playstation 4 for Blu-rays, Netflix, Amazon Instant Video, DVDs and games.
Settings > Sound and Screen > Audio Output Settings
Primary Output Port = HDMI OUT (with Output 5.1ch Audio ticked)
Audio Format (Priority) = Linear PCM
Pressing Triangle during a Blu-ray shows "AVC DTS-HD MA 7.1ch 48kHz" on the Blu-ray menu.
Dual Shock 4 Options button > Settings
Audio Format is set to Linear PCM (Noise Reduction and Dynamic Range Control are Off).
This is now only used for games.
Video Settings > BD/DVD - Audio a Output Format (HDMI) > Linear PCM
Sound Settings > Audio Output Settings > HDMI > Automatic (picks up all supported formats of my AV)
Surround setting (Sound Field) set to HD-D.C.S. > Studio
HDMI Settings > Ctrl for HDMI set to Off and Audio out to AMP
Now with all the above settings, in menus, Blu-rays, games, Netflix etc the receiver always shows the following on the front panel display:
LPCM  KHz
Is this expected? And with the above settings, I will be getting the uncompressed lossless audio to my speakers?
Oh and Sky HD is connected using Optical and shows Dolby Digital 5.1 on HD channels on the AV and LPCM  KHz for non HD channels.
Any clarifications or advise would be much appreciated to ease my mind
I'm very picky about these things and always changing settings around and reading online, but just does my head in when I hear conflicting comments!
Thanks a lot all
