FOSS gamedev and creative worlds

Since some time i don' get any sound from Minetest anymore. I downloaded a fresh version of Minetest but it still doesn't work. Maybe it's because i upgraded to Win8 but i got Minetest running on my Win8 Laptop too and there i get sound. Anyone knows what to do? (It's very stupid because i do Let's Plays)

Sry didn't see the other No Sound post.

Problem solved
