Does it loop during playback or when you do a render/preview?
In max 9 at least, it does not loop in playback, and you can set where the sound should start using the WAVSound.start = 100f
That will make it start at frame 100.
If you want to render it with no looping, then I guess there has to be a way where you can run a short script before it renders each frame. It could mute the sound completely at frame 0 and check for a specified range you give it and un-mute it where you need it. (that range could be the WAVSoundl.start and WAVSound.end range if you set that)
hmm. If not, Sound Trax would do it plus a lot more, at a price:

I could be very wrong about this, those ranges might only apply to playback :/
