Dual audio for Wetek and Generic Build

Hello,

I want to ask about dual audio output. I see that there is a unofficial update for this: Index of /LibreELEC-DualAudio

I notice that with oficial Libreelec build for Raspberry Pi, I could select both audio outputs (analog and HDMI) and it works.

Is it possible to add this in Wetek Play and Generic builds?

I want to use HDMI for TV and the analog to send sound to the rest of the house.

Best regards.
