I have same problem. I got no sound card, I use integrated soundprogram Realtek HD audio and other option is straight speaker settings. Reinstalled and updated both, but AoW: SM sounds donīt work. Have no issue with any other game or program sounds.
I use win 7 options without direct 3D in AoW: SM to make it work almost properly. Win 10 mode it wonīt start at all. Canīt find any other integrated program to deal with. I think Realtek was known before as Soundmax.
Oh this is for win 7, my problem is in win 10.
