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.
Perhaps the Xine problem is caused by the passthrough mode. E.g. in mplayer the hwac3/hwdts output decoders for passthrough run in 16bit only, but they work actively with the non-audio format. You can check xine/xinelib code, the alsa output should not be that difficult to analyze.
