It's essentially unchanged, before and after the patch, with aplay(*)
and xbmc, except for 'momentary freq' which varies of course, but stays
in the neighbourhood of 192k

Would a graph of the momentary freq trend for a minute of playback be
useful at all?
[*]: I'd like to take back the comment I made in an earlier email
claiming that only xbmc without that patch would play 24/192 correctly.
As a matter of fact, aplay works fine without the patch, and fails the
same way with it, kind of a good news I guess. In addition to more
recent versions of xbmc, the one command line utility that never plays
back 24/192 correctly, with our without the patch is 'play' from the sox
package.
