No optical signal output from HiFi Shield Plus

[davispoon]

ODROID C1+ with HiFi Shield Plus.

MPD: Audio Output Interface = ODROID-DAC. Can play music from the RCA output.
MPD: Audio Output Interface = ODROID-HDMI. No optical signal output from the Toslink jack.

Any idea? I need optical signal from the Toslink jack. Please help.

Maximum number of characters reached, so I can't directly post the debug in here.
I saved the debug in .txt and tried upload it as attachment.
No luck, got error message... The extension txt is not allowed.

What can I do? Please advice. Thanks.

This is the top part of debug. Hope it helps.
