Playing with v1.0.4e music off but sound on, I had now two times a problem where during the battle resolution no sound was played. The first time the game eventually crashed after e few battles, yesterday after some battles it moved on to the next phase.
I think both times it was the second movement resolution phase where this problem occured, didn't notice any sound problems in the first one. I think I have the streaming option selected, not sure whether it has an influence on the sounds or just the music.
