Okay so the short of it is that I had DTS and DD5.1 working flawlessly with my PS4 Pro and my (ageing) Sony HT-SS1100 5.1 speaker setup for the past few years. I also use the amp with my Sony 4K UHD player via the co-axial output and my Xbox One X via the second optical out (VIDEO).
PS4 Pro connected to Sony amp via Optical Out (SAT).
Because the PS5 lacks an optical out port I have had to reconsider how the amp is setup for 5.1 surround sound. Luckily my LG B9 has an optical out port which I have never considered using until now (to be honest I forgot it was even there).
I have now connected the Sony amp to the TV via the optical cable (using SAT as by the PS4 Pro) and, obviously, my PS4 Pro is connected to the TV via HDMI.
In the PS4 Pro's Audio Settings I have set the sound output from Optical Out to HDMI since the optical cable is no longer connected to the console and instead the audio is being fed via the HDMI port. The Audio Type is set to DD5.1 (I also tried DTS but it is exactly the same).
On the TV, in the Sound settings, I have enabled the Internal Speaker + Optical audio output option (allowing the use of the TV sound and the amp for convenience) and set the Audio Type for HDMI 2 (which my PS4 Pro is connected to) to Bitstream.
However, when I watch a movie, say, Star Wars: Rise of Skywalker on Disney+ on my PS4 Pro the Sony amp shows the audio as PCM 48 MHz and only uses three channels. It is also really quiet.
Why am I not getting DD5.1 from my amp?
The PS4 Pro is outputting DD5.1 to the TV and the TV is set to Bitstream (not PCM) but I cannot get anything other than very quiet stereo sound.
What I am doing wrong?
