Hi all
Sound work via expansion board for jack connector and HDMI via main bord and also via I2s work on orangepi zero 2w with the i2s0 pin, pi0, pi1, pi2, pi3 and pi4 for i2S
You Need to apply an overlay to activated it on the device tree and choose some clock with a script
I succeed to have sound with a Dac PCM5102A, with HDMI and jack connector and USB external device
