[Bug 38313] broken surround sound in skyrim (and possibly games which do not have advanced sound settings)

https://bugs.winehq.org/show_bug.cgi?id=38313

--- Comment #6 from Yuki  ---
currently, I am not using any .asoundrc. The one I used would mix sound to a
4.1 setup, even if it was stereo only. I used it to see if this could work
around this wine bug, but it didn't.

Anyways, here's the terminal output. It's quite long, but the part which does
not have center sound comes at the end.
This is on a new wineprefix, only apps installed are steam and skyrim along
with it's dependencies. 
(It's also a modded skyrim game, but there's no difference in sound. the
missing front/back sound also happens for vanilla skyrim)

used wine version: 1.7.41 WoW64 setup (via emerge installed, gentoo x64)
