Yes i do.
I have already tried it with both AddOns enabled and without, as well as a shader injector (also tried it with and without).
However after some more hunting I tried to link with an older version of mumble and the version 1.3.4 seems to be working without any problems.
So it looks like the new stable version 1.4.230 seems to be the problem with a bug (makes sense considering they rewrote the plugin framework), so if anyone has the same or similar problem; try to use an older version of mumble namely 1.3.4 works well.
