No Analog (PCM) audio on Ugoos AM6B +

Hi,

I just installed Coreelec on my new Ugoos AM6B+. All audio works except Analog PCM via the AV out socket which is silent.

Is this a known issue? Any fix? The problem is there both with the latest v19 and v20 builds of Coreelec.

This problem was reported a while ago.

Thanks so much if anybody can help get this fixed!
