Hey, as the the title says im having issues with surround sound playback on blu rays on the ps5. I have looked all over the internet people seem to have similar issues but their fix does not seem to work for me. So I have the PS5 connected to my LG43UH650V tv, then an ARC out to a Sony HT-RT3 5.1 system, The PS5 HDMI device type is set to AV amplifier the channels set to 5.1 audio format set to Dolby. This is where i have noticed the usual fix comes in going into the setting and changing the audio format to bitstream works for other people, if I change this from PCM i get no sound at all, i cannot work out what im doing wrong, PS5 games output in 5.1, i have a sky q box set up and it works fine, I had similar issues with the PS4 but was solved easily buy using an optical cable (no optical port on PS5). Any ideas or work around's would be welcome. My only other option would be to fork out for a 4k blu ray player with optical support.
