Digital out is TOSLINK. https://en.wikipedia.org/wiki/TOSLINK

Most good audio gear still has it though it is very slowly disappearing.

Thank you. Totally get it now.

TOSLINK is dissapearing because it lacks support for high bitrate audio.  Most soundbars and home audio equipment uses HDMI ARC to get audio and control inputs from the TV.
