What type of audio is it?

Try "open copy in" instead and see if that works.

In this project I have used two cameras. One of them captures in AVI and the other one in MPEG. In Vegas when I try to use the audio editor for AVI files it works, for MPEG files it does not, but I tried as you suggested to open a copy of the file it worked.

Probably the audio from the MPEG camera is AC3 and Sound Forge won't open that. When you "open copy", Vegas renders out a .wav version for Sound Forge to use.
