Although I'm rendering to QuickTime, my final format is Flash Video, and I need to hear it, of course, and ensure it'll work for the client, too.
Upshot: Go to Audio MIDI Setup program, and make sure the audio output being used is set to 44.1KHz sample rate....
I think this happens because I use a laptop, and sometimes plug in an external audio interface. OSX gets confused, I guess, and changes my settings without telling me....

Flash video and no sound on OSX
One of the newer technologies on the web are the flash video players used by Google Video and YouTube.
Every once in a while though, on Mac OS X it can happen that these Flash video players don’t have sound anymore.
It is pretty hard to figure out why, and the solution is quite random, but on macosxhints I found a comment mentioning that it could be a sampling rate problem:
1. open /Applications/Utilities/Audio MIDI Setup
2. check the properties for Built In Output.
3. It might be set to 96KHz. Change it to 44KHz and audio in Flash will return immediately.
Now, I don’t know what software it is messing up that setting, but I am glad it can be fixed.
