When using package search for tumbleweed:
https://software.opensuse.org/search?utf8=✓&baseproject=openSUSE%3AFactory&q=wine-staging-nine
the 1-click installer says wine-staging-nine is in the standard tumbleweed repo so I would go for it:
http://download.opensuse.org/tumbleweed/repo/oss/
I’m guessing you already have this repo added if you are using tumbleweed.
Not sure what is ESYNC though. Is this a package name?
Solved, Stagging4.6 does support it by default.
