Attached is my savegame along w/ config & console files that has an intercept from one of my bases to a alien fighter. I've tried slowing the time down, I normally leave it at 20min setting when I've got intercepts going on, as well as zooming in from my current setting as well as turning sounds off - none of which has made a difference. I had a 2.4dev (somewhere in march build I believe) that didn't have this problem & I didn't have sound on the geoscape during intercepts but did have sounds on battlescape on that version. I deleted that version from my pc when I installed the official 2.4 release.
