Oppo DBP 93 - No sound out of Multi Channel Analog Outputs

[SK1972]

Good Day All

Any suggestions or advice on how to resolve this matter.

I believe it could a simple setting issue.

I need the output to work for SACD.

Note SACD signal cannot be transmitted via Toslink & Digital Co Axial due to copyright matters.

I welcome any feedback.
