Default [Q] ATV1200 Composite Out

I have a Genitech ATV1200 and just installed the test build of the MX_Linux abd everything is working fine but i'd like to be able to use the component or composite output of the box sine this box is hooked up to an old television, I was able to do this when i was using the original firmware with Android but now with MX _linux it only output to HDMI.

Is there a way to activate the composite or component out connector on the box with a mx_linux firmware ?

Thanks all for your help.
