I turn my game sounds off while I am doing other things. I too have other programs open and have music playing on my PC while VV runs.

However, if I go back to VV to check on things, sometimes the sound comes back very briefly. It may just be the sound of the ocean or a 5 second clip of the music. But I have checked several times and I have the VV sounds and music turned off.

This also happens with FT, too.
