Please, please do submit a bug to pulseaudio.org. It is undeniably a bug in
either PA or alsa_plugins when restarting the PA server fixes sound.
I can't submit a bug report that would be taken seriously because I'm using the
outdated Ubuntu Intrepid and Lucid, though I've been liasing with the PA guys:
http://lists.freedesktop.org/archives/pulseaudio-discuss/2012-February/012834.html
But you're using the newest PA and plugins there is and still facing issues.
Well, perhaps I should go to the PA bug tracker and post your logs?!?

Then hopefully, there will be less PA issues in the Wine bugtracker.

This PA bug number 2:
>render.c:1204: hpctime 460 pcpos 466
>render.c:1209: padding 0 position 22500/22500 slept 450ms iteration 0
>render.c:1204: hpctime 584 pcpos 590
>render.c:1209: padding 10980 position 34020/34020 slept 550ms iteration 1
Within 124ms, PA pretends that the speaker position as reported by
snd_pcm_delay advanced by 249ms. That cannot be.
>render.c:1217: Test failed: Position delta 12960 not regular
Same here within 103ms.
>render.c:1209: padding 6720 position 152100/152100 slept 1250ms iteration 8
Here it pretends to be at 3.168 seconds within the stream after solely 1.327
seconds elapsed.  That is PA's buffering, not a speaker position.
Please attach the corresponding WINEDEBUG=+alsa,+tid,+timestamp log.

That's the one bug on the Wine side:
1. We need to perform tests to check whether CreateTimerQueueTimer's current
behaviour is correct. As observed in bug #28723, comment #126 and #130, unlike
timeSetEvent, it does not maintain a constant pace. Should it?
2. Depending on results, either fix TimerQueue or choose another time base.
