DTS overlay to activate I2S DAC 5102a on Armbian Buster 5.4.43

armbian-add-overlay sun50i-h5-i2s0-out.dts

If you don't have headers armbian-config (software->headers)

 

Manual install whithout headers

mkdir /boot/overlay-user/
dtc -I dts -O dtb sun50i-h5-i2s0-out-no-header.dts -o /boot/overlay-user/sun50i-h5-i2s0-out.dtbo

add user_overlays=sun50i-h5-i2s0-out to /boot/armbianEnv.txt
