Thank you for getting this resolved so quickly.
I can log in the game, but there is no sound. The audio sliders are all set to 100.
All of my hundreds of other games and applications have no problem with sound.
Edit:
I was wondering what the audio option box "Total sound" was, but it didn't seem like something with that name would be a level adjustment or toggle. When I checked the box, it didn't change anything so it was a mystery but confirmed my impression. Well, out of desperation I checked the box again, still nothing happened. While I was sitting there contemplating the situation, I noticed that there is a button at the bottom labelled "Apply". Try clicking on that, dummy! Sure enough, now there is sound! Whatever...
