The log I attached already contained additional traces I added, not found in
the original wine source (maybe I should submit them as regular patches):

trace:dsound:DSOUND_MixInBuffer buf_mixpos=46690/48001 sec_mixpos=21448/44100
trace:dsound:DSOUND_MixInBuffer buf_mixpos=47984/48001 sec_mixpos=22042/44100
trace:dsound:DSOUND_MixInBuffer buf_mixpos=48000/48001 sec_mixpos=22050/44100

nAlign is missing, I'll add that (when I'll be back from holidays).

What always puzzled me: is 48001 a sane value for the size? I understand where
it comes from (rounding issues when calculating / inverting buffer sizes for
resampling from 44100<->48000), but I wonder whether such an odd buffer size
might participate in causing the bug (I.e. it may break the boundary/end of
buffer detection)?
