I have "Source number of channels selected" and JRSS is enabled. I tried switching to 2 channel stereo and 2.1 as that is what I have, but it made no difference.
I found that switching from ASIO to Direct Sound fixes the problem. I have not had similar problems with any other movie.
One other thing, I'm not sure if I should start a new thread for this, but while playing around trying to fix this I found that the controls at the top of the screen would not reappear. You know how they disappear when you aren't doing anything so that you can enjoy the movie without looking that the control bar, but when you move the mouse they should reappear. The only fix has been to close the display view.
