Audio peaks when uploaded to YouTube!

I hope 'peaks' is the right word.


When I render my videos in Sony Vegas, the output video sounds just fine. After being processed by YouTube, however, the audio peaks! It sounds all staticy and terrible... This has never happened to me before! I tried rendering it again, though -- but this time without surround sound, which I had been using. Works just fine in stereo.

What can I do to prevent it from peaking when using surround sound in my videos? Does YouTube simply not accept it? Cuz I could have sworn I have seen some videos with surround sound... I wonder what settings they use?

If you really need surround in the final product, use an LtRt codec like ProLogic.
