Unless I'm misunderstanding you, you can choose a channel output from the settings.
Be it 2.0/5.1/7.1 and so forth.
those settings appear when connected to a AV Receiver
No not at all, I get that. I'm just wondering whether it sends out height data or if the height effect is just recreated by modifying the existing 2.1-7.1 channels. The other replies here saying that DTS:X/Atmos isn't implmented/relevant in games seems to indicate you won't get any real height data though.
So for instance, disregarding the 3D audio, if you have a 7.1.2 receiver with real in-ceiling speakers connected to a PS5 I think it just has to use its own in-receiver processing (DTS Neural:X or the confusingly named "Dolby Surround" upmixing solutions) to get audio into the real ceiling speakers.
So I'm wondering if when you use, for example, a 5.1 soundbar (3.1 bar with two rear speakers) but with the new 3D audio turned on, will the audio signal sent out contain extra height channel information generated by the Tempest audio system from the original audio output from the game that the soundbar can use to aid its own internal 3D audio processing or will it just send out a 5.1 signal with frequency modifications.
I'm thinking the latter now I've heard from others. Its probably just not how game audio output works, as kyliethicc says below, ie never contains height data. I'm just wondering if it does because I did tests with Sonys Vertical Surrouns 3D spatial audio system on its soundbars and the only content that actually sounded like it had height channels was the audio sources which already had height channels, even if I didnt have the physical speakers to output it.
Hope that all makes sense.
Yeah its all just pointless DTS/Dolby encoding by the console on a system level. Has nothing to do with the game.
My understanding of it this:
Console can send the game audio out as PCM or as DTS / Dolby.
PCM means no work for TV/AVR... Done, simple.
Using DTS/Dolby means the TV/AVR has to decode that signal... Why bother?
Kinda a waste of time given the source content wasn't mastered in either one. We'd basically just be asking the console to say, encode a DTS signal for the receiver to then decode again. Kinda pointless double work for no real gain. I just use PCM for games on my PS4. Sounds great. Only downside is my AVR's little blue light doesn't light up (since its not decoding.) Oh well lol.
Its a constant source of pointless pain that I can't get the decoding logos when using PCM/LPCM lol, as you say its just pointless decoding though. I hear no difference in mix/quality/whatever between LPCM output and DTS-HD from VLC (Which is easier to test than comparing on PS5).
Off Topic: This came up while I was searching just now and I forgot about it. I think its why my 1080p blurays have been looking like toasted shit compared to VLC/mpv on the PC (I swapped back and forth on the same frame of the disc in the PS5 and an ISO of it on PC and it was night and day different in terms of image quality, which baffled me), so just a headsup for others to turn this awful crap off when watching good quality content:
