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.

Sure if the rate is changed (the source code suggests only the low-quality linear rate algorithm supports above-16bit format - operation convert, the other resampling algorithms convert using the operation convert_s16). Ice1724 supports all the general rates natively, the rate conversion in the plug plugin should not kick in for common audio formats. The only case I can think of would be switching Juli to external SPDIF-IN clock - the hw.rate_min = hw.rate_max = actual_rate and the automatic rate conversion could happen. I did not use the hw device in my tests since all the tested tracks would have to be 32-bit for the hw device to accept the format when played via my favorite aplay. My 2 cents guess is xine does the conversion.
