NanoPi NEO v1.2 analogue audio


I have nanopi neo and I want to get analogue audio to work.

'aplay -l' lists the soundcard (analouge and hdmi), so it seems that the
linux driver is loaded properly. Also the audio_used flag is turned on in
the fex script.bin

Turning of the 'audio0_used' in the fex file results in 'aplay -l' showing
no card anymore ... so this is ok.

But for some reason there's no sound output on lineout l/r.

I have tried official friendlyARM image and Armbian => Same situation.

I had a look to the H3 Datasheet and lineout l/r needs to be connected to
AA3 and Y3 but I can not verify this.

Any ideas?

Best regards,
