Well, I guess this is a left-over from my experimenting with the 
unpatched alsa output module. And your distribution applies the 
non-upstream "pulseaudio output" patch.

So, please add this registry entry to reproduce the test result:

[HKEY_CURRENT_USER\Software\Wine\Drivers]
"Audio"="alsa"

regedit alsa.reg

But it still boils down to a low-latency stream.
