Okido, it seems to work (it is however a rather strange sound but ok)

thanks for the fast reply!

Dear Fellow-Factorios,

I installed the steam - game, but have no in game music. I do have soundbites (e.g. mining sound etc).

I run an windows 8, 64x, specs are ok.
I have tried restarting my computer (I read this somewhere, after installing) but it does not change anything.

Can someone figure ...
