DVD burning issue, no audio...

I've recently bought a new laptop. It's an ASUS x54c. I have a bunch of videos on my external hard drive that I'm trying to burn to DVDs. I've used the Windows DVD Maker and also I've used Nero 7, which I've used both on my old computer and they both have worked fine, but both programs on this computer burn the video with no audio. I've tried uninstalling and reinstalling, I've tried updating the drivers, and I've tried also using an external DVD drive. In fact, the last time I tried it using Nero 7, I clicked on the preview button, before burning the disc, and the preview doesn't even have sound.
