Audio quality problem

Hey-ho.

I’m using a wav file in my movie, (this one to be exact http://www.thinkroadsafety.gov.uk/campaigns/drinkdrive/download/insurance.wav) and I’ve set it to stream so I can animate around it. I’ve been in to the publish settings and whacked everything up to maximum for audio streams as I normally do but it still exports really crackly for some reason. I’m able to get good quality out of it when it’s set to event (with the export settings on max again) but it does not stay in sync with my movie.

I’ve animated to streaming audio a few times and I’ve never noticed this problem before… could it be this wav file? Or am I going about this the wrong way? Thanks in advance.
