Allo Piano 2.1 modes selection in volumio

Hello I recently purchased an Allo Piano 2.1 but can’t seem to activate the subwoofer mode, specifically I’m hoping to set the Dual Mono mode for better sound quality. Is the option supposed to be found in volumio? It’s not showing up on my latest version 2.692.

Do I need to install any allo piano firmware to access it? I’m currently using a macbook pro and not too sure how to go about it.

Appreciate all the help I can get. Thank you!

This was fixed in public release v2.806.
