This case is a bit confusing. I have tried to look at the realted bug
reports this morning. (nothing seemed to have happened since
There are mentioned two patches for Wine that should fix some of the
problems, like the bad hard coded defaults on names for default
devices and volume controls. (here: pulseaudio.org/ticket/198 and
winehq.org/pipermail/wine-patches/2008-February/050561.html ). I
wonder if they are included now? (Really a question for people working
on the wine code)

What about Wines OSS and ESD output? If they work, it could be
recommended to try these if alsa output does not work.

Note that there are reported separate problems with DirectSound

Because Wine is not "just working" (or has been working badly
recently) it also deserves to be mentioned at the wiki at
pulseaudio.org (So I'll try to do that).
