When you first boot up and it brings up the "play", "settings" and "view readme" I get sound there, but other than that, I get nothing.
No sounds in game at all, music, SFX, nothing.
Anyone have any ideas?
I let it do the auto detect and it found my sound card straight away, but it's just not working.
!EDIT!
Whoops, never mind, brother just told me that what the problem was.
I had it on digital output HD sound, and we kinda don't have that. Speaker sound is working :)

Ya I had same problem, seems default under device search will put it under HD output.
I changes it to just "primary sound driver" and that fixed it for me.

Thanks. I had the same problem and your post helped me. Pity it can't just start with "Primary sound driver".
