Pirate Audio - LCD in both Speaker & Lineout does not work

I recently bought it and using it with Raspberry 3B+ / Volumio latest version.
Sound is relevantly working but display is not working even though I follow your instructions as below.

Please copy right CLI command below to properly activate LCP in both items.
