It appears that this breaks other software such as skype[1], and the
workaround would be to actually raise the latency. Quoting from the
link:

====
Applications can ask PulseAudio for the latency that they wish to have
(the amount of time between writing out a sample and it being played
out the speaker/headphones/whatever).

Skype seemed to have some weird buggy math that only kicked in at low
latencies (20-25ms or less) that caused the problem you saw. Setting
PULSE_LATENCY_MSEC forces the requested latency (60 is pretty safe
across most setups), making sure this bug in Skype is not triggered.
====

Rather than change the default, perhaps wine can set
PULSE_LATENCY_MSEC? Applications that are buggy with too high or too
low latencies will probably exist always. I don't know what should we
do in this case.
