: First of all, I can't remember, but there may not be any 16-bit sounds in
: Rubicon, so try unchecking the 16-bit sound preference (IMO, Bungie should
: have set it up so that 8-bit sounds are automatically substituted when the
: 16-bit versions are absent, but there's no reason we can't do that in AO).
: If that doesn't work, make sure that the Rubicon Sound File is present,
: and that it has a proper file type.
I did some quick checking, and you were right: there are no 16-bit sounds in the Rubicon sound file. Hopefully, unchecking the preference should be all that's necessary.
