No Audio With Render

I’ve done nothing different than I have in the past. I edited the video, I rendered it, then uploaded to YouTube. No audio. I opened the file on my computer in Windows Media Player, and no audio. I’m using Vegas 9.0 and I can not even see the wmv file in Vegas, but can open my .vf file and the audio is there. This is a very simple video just over two minutes long. No music, only the audio recorded when I made the video. I’m trying to render it again, but for some reason, I don’t expect it to work. What is causing this?

Well, I rendered it, and uploaded to YouTube, and it worked this time. I did nothing different. I’m clueless as to why it didn’t work the first time, but at least it worked.
