X90J, PS5 and old DVD 5.1 surround sound compatibility?


Novice Member
So my Sony 5.1 DVD (lol) surround sound player supports 5.1 via HDMI but only if playing DVD movies from the player itself. Otherwise it will only take an optical INPUT for 5.1 surround sound.

Obviously the PS5 has no optical output, so what are my options?

The TV I'm looking to buy is the X90J which I believe has optical output? In which case do I just plug the PS5 into the TV HDMI 2.1 port then plug an optical cable from back of the TV to the surround sound? I've heard this can cause issues on some TVs such as delayed audio, and it also means you have to watch TV in surround sound which isn't always appropriate especially late at night. I know you can get converters from optical audio to HDMI but none of them support HDMI 2.1 and 120hz.
