Raspberry pi 5 with latest volumio os and R-PI DAC board no optical audio output

Hi all,

Just want to know anyone using the same R-PI DAC board as me? This DAC board not able have the optical audio output, is that any configuration need to change to support the optical audio output.

the RCA and 3.5mm audio interface is working fine.

I tried all setting I known but still no result.
