It is incorrect. Release date is Dec 2018.

aplay -D hw:1,0 /storage/music/44.wav -v

it doesnt play because ice1724 is waiting for 32bit data (although file is 16bit)

But if you change to "plughw" (aplay -D plughw:1,0 /storage/music/44.wav -v), the sound appears. If you change nothing in asound.conf, the sound is 48000 Hz constantly, independently of the file being played.

This is normal. ICE1724 only supports 32 bit format and the default alsa configuration (default:0 pcm) uses the dmix plugin with a fixed 48kHz rate - this is identical to how it works on other Linux distributions.

You either need to access the hw: device in 32bit or use plughw so it can auto-convert other formats to 32bit.

so long,

Hias
