Lost audio

I've lost my multi-cam editing audio. It was there the first time I started
editing. Worked like a charm, now it's gone. The audio is in all of my
sequences, in Audio One track, it's linked to the video in all sequences, but i
don't hear anything when i go to multicam editing. i can edit with just the
video and when I play back my edited sequence the audio is there, but I can't
hear it when I'm editing.... HELP what do I need to check. I must have changed
something inadvertantly, but I don't know what. It make no difference if I check
follow video or not.

Chris I'm new to multi-cam editing also, and just ran across this problem. Not
to worry, I figured it out, even though the book doesn't have anything to say
about it NOWHERE!

Wow...this is a huge help to me, also. I was stumped and I could not figure out
why I couldn't hear the audio.
