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

Christian2607 Thanks for manual!

 

after  aplay -c 2 -D plughw -f S24_LE -r 48000 /dev/urandom

 

I see only format: S32_LE (not 24 bit) it is normal?

 

I can't set 24bit mode.

 

Sorry, all right. aplay convert 24b to 32b, mpd working is normal, output = 24b!
