i've searched many times, never really found a solution, or even the cause, of my problem
there are certain FMVs that are completely without sound, or cut out halfway through. some examples are
the near beginning fmv in which the reactor explodes (no sound whatsoever)
the soon acompanying scene in which they blow up the rubble to get through (gotta love Wedge's little run around with fire
).
there are many other in which the sound cuts out either at the beginning or halfway through.
i can live with this, but im just curious as to if there was ever a fix, solution, or reason, found for this.
