I hope someone can help me with this odd problem. My setup is as follows:
Sony vegas pro 9 (64 bit version)
Windows vista 64 bit
My sound works fine in vegas while im editing and my music tracks that I add to my movies play along happily. But when I render my movie and play the output file, there is no sound. Nothing. I have tried toggling between the different audio options "windows media audo 9.0" etc but nothing seems to work.
Im guessing there is perhaps a codec which I haven't installed but then why does the sound play from within vegas but not when playing the final movie file? I've also tried playing the output files on other pc's with windows xp which does the same thing.
I would ideally like to not have to use some lesser used codec with my movies so that the majority of people who watch them can play them without problems.
