Stereo PCM on Blu Rays through PS4 Pro

Hello, I've been trying to watch Blu Rays on my PS4 Pro and it's been driving me nuts that every Blu Ray with DTS tracks transmit as Stereo PCM.

My System: Sonos Beam (1st Gen), Sub (Gen 2), two Sonos One (1st Gen), PS4 Pro, LG C1

I recently bought an LG C1, and annoyingly the TV doesn't decode DTS Audio, so I understand why I can't get DTS Audio; however, Stereo PCM makes Blu Rays a worse option than streaming. I have my PS4 Pro set to HDMI audio, and Bitrestream (Dolby). I have tried the LPCM option, Bitstream (Dolby), and Bitstream (DTS); none of them fix the issue. I've also clicked the start button within a Blu Ray and changed the Audio Format to Bitstream.

I have my C1 set to HDMi(Arc) for Sound Out, eARC enabled, Digital Sound Out to Auto, and HDMI Input to Bitstream. Ice tried Sound Out to PCM/Passthrough with no success. .

Am I just stuck with Stereo PCM or am I missing a step? Thanks for reading!

TLDR: PS4 Pro Blu Rays decode as Stereo PCM on LG C1

Was actually planning on upgrading to Sonos Arc once tax season starts. Once I do that I'll move the Beam Gen 1 to the bedroom. Is setting the PS4 to Bitstream (DTS) how it'll convert the audio to PCM?

I believe Audio Format (Priority) should be set to Linear PCM. Then as the film is playing, tap the Options button on the controller and set Audio Format to Linear PCM too.

If this doesn’t work, set the former setting to Bitstream (DTS) and the latter setting to Linear PCM.

I think I tried that combination before, and if I recall it didn't work. I'll try that again later today. I don't think Be Gen 1 decodes LPCM either because it isn't eARC.

Correct. Those PS4 settings are when you upgrade to the Arc or Beam (Gen 2).
