Sorry for delay, tried that, with no luck :L It is strange that the Heart of the Beast mod with the werewolf howl sound fx works in MO for me, and the others dont. Installing AOS manually, (Outside MO, in the Skyrim-Data folder) alongside Immersive sounds, works fine, which is kind of annoying changing in and out of MO, as I would rather have it all in one place, but hey could be worse right :)
