    No solution, but another data point.  I have two systems with
Alsa (0.5.10b generally), with the VIA686 codec, and on both of them
I can fairly consistently get a process hung inside an open call
in the Alsa driver (only with Wine).  For me, I don't lose my system, 
I simply have to reboot in order to recapture sound.

    I discussed this in substantial detail with Ulrich Weigand on
wine-devel,
and we came closer to understanding the problem, but we have
not resolved it.

    At any rate, I don't think that's enormously helpful, but
you should know that you're not alone.
