Your aplay handles already 24bit correctly. ICE1724 supports only 32bit natively (as most modern cards do), and hw:0 correctly does not accept any other format. That is why plughw converts your 24-bit format to 32bit - see the verbose output. For testing purposes make a 32bit file (sox -V in.wav -4 32.wav), and aplay -v -Dhw:0 32.wav will play fine.
