In previous releases (when Fedora carried winepulse) this bug would have landed
solely in Fedora bugzilla.
However, given the fact the bug *only* gets triggered by wine (other alsa-pulse
applications such as flash-plugin do not exhibit this) and given the fact that
as far as I can see, Fedora uses more-or-less stock wine, I rather try here
first.

I restarted PA manually on two machines, one of Intel-HDA and the other with
Audigy 2, tried VLC and got the same results.
Just to verify that PA is indeed working, I played a short springrts game (oh,
life is indeed tough :)), and played a short flash video (non-HTML5).

Tried using winecfg to select another device (instead of default) - no go.

... Please, please, please don't break pulse.

Attached.
