In Diablo 3 just create a new character and take up a diary in New Tristram. The voice that is reading from it is very quite while other sounds are normal.
I found a book inside a house called "Deckard Cain's Journal" that plays an audio clip. Is that what you're talking about?
It sounds fine for me. Can you check that your speaker configuration in winecfg is correct? What sound driver does winecfg say you're using?
