I confirmed that aplay and plughw:0,1 work fine. Aplay and hw:0,1 don't work at all.

And that Xine is the culprit. Now to find out how to fix/work around Xine.

The older aplay you most likely use does not support 24bit properly. Install the latest alsa-utils from git and you will be fine.

Sorry for confusion. 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.
